Receptacle Style; 180 to 2000 nm; Coupling Efficiency >60% to >80%; Backreflection -14 to -60 dB; Power Handling >1 to >100 W In OZ Optics' HPUC series of receptacle style, non-contact style laser to fiber couplers, an air gap exists between the fiber and the lens. This design is more flexible, allowing a wide range of lens types and focal lengths to be used. The distance between the fiber and the lens can be adjusted to compensate the changes in the source wavelengths or to intentionally defocus the laser beam to prevent arcing in high power laser to multimode fiber applications. Couplers using GRIN lenses, achromats, aspheres, fused silica, plano-convex, and biconvex lenses have all been made utilizing this design. Non-contact style couplers can handle input powers of up to 100 W CW, and even higher energies from pulsed sources. They are best suited for applications where either the input energy is higher than 400 mW, or when more than one wavelength is to be coupled into the fiber, or for input beams that have unusually large beam diameters or divergence angles. They also have superior polarization maintaining capabilities compared to physical contact style couplers. However because of the air gap between the fiber and the lens, the backreflection level for the endface of the fiber is about -14 dB. This can be reduced to -40 dB to -60 dB by slant polishing both fiber ends to deflect the backreflected signal. There is a significant variation in the endface geometries of angled PC (APC) connectors. This effects the spacing between the endface of the fiber and the lens. To minimize this variation, OZ Optics offers an angled flat (AFC) connector. This connector features a beveled endface where the fiber itself is angled but the ferrule tip is flat. This geometry provides optimum repeatability between connections. For users of SMA connectors, please note that standard SMA connectors and receptacles are constructed to rather loose tolerances, leading to poor repeatability. For core diameters of 100 µm or smaller, we recommend using SMA connectors with Zirconia ferrules and receptacles with Zirconia sleeves. This will give maximum repeatability. Better still, consider using FC connectors instead.

Fiber Type Single Mode, Multi Mode Step & Graded Index; Input Core Diameter 100 to 600 µm; Output Core Diameter 50 to 200 µm; Numerical Aperture 0.12, 0.26; Wavelength 180 to 2400 nm; Sheathing PVC, Stainless SteelFiberguide’s AFT/SFT series of optical tapers are used for mode mixing, lowering optical power density in high power applications, and converting numerical aperture (NA) in optical power delivery applications. Optical tapers can either be tower drawn, where the length is several meters, or they can be produced using bench-top equipment, making the length a few inches. In both cases, these optical tapers are continuous pieces of fiber, they are not spliced. Tapered optical fibers can be made either by fusing a short tapered section onto a longer fixed diameter fiber or by very carefully controlling the drawing process to produce a single continuous fiber with an integral tapered section. For its AFT/SFT series, Fiberguide uses the latter process since it results in superior fiber strength, alignment precision and optical power transmission. Tapered optical fibers cause optical mode mixing that tends to homogenize spatial power distribution. A larger input core diameter can prevent input damage and allow a smaller diameter pigtail for convenience in adapting to a wide range of optical applications. Tapered optical fibers can be used as a passive optical component to alter the input and / or output divergence (N.A.) with regard to an optical fiber, as a high power coupler for laser energy, as this will spread the energy over a larger area, or simply as a device to relax tolerances in an optical system. To ensure maximum efficiency of light transmission, the numerical aperture (N.A.) of the light entering the taper input should be 0.22 divided by the taper ratio. As an example, assume the input core diameter of the taper is 400 µm and the output core is 200 µm (2:1 taper ratio), then the N.A. of the light entering the taper will be 0.22/2 = 0.11.Additionally, the fibers can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.

Wavelength 450-200 nm; Pigtail Type SM, PM; Rise / Fall Time 6-100 ns; Operating Frequency 40-300 MHz; Fiber-coupled acousto-optic modulators (FCAOM) offer a robust solution for amplitude modulation of fiber lasers, allowing direct control of the timing, intensity, and temporal shape of the laser output. Gooch & Housego’s (G&H) Fiber-Q® modulators offer high extinction ratio, low insertion loss and excellent stability in both polarization maintaining (PM) and non-PM formats at modulation frequencies up to 80 MHz for visible and infrared wavelengths. Built for reliability, the Fiber-Q® series of products features a rugged hermetic design in a compact, low-profile package, ideal for ease of integration into all-fiber and OEM systems, including medical laser systems.Each Fiber-Q® acousto-optic modulator requires an RF driver to generate the RF signal creating the acoustic wave within the embedded AO crystal. Modulation of the beam through the Fiber-Q will depend upon the frequency and intensity of the applied RF signal. Contact our sales team to identify the best RF driver for your specific application, taking into consideration the type of modulation required (digital or analog) as well as any specific pulse shaping needs.A fiber-coupled acousto-optic modulator (FCAOM) can directly control the temporal characteristics of the active output from a fiber laser, offering a wider variety of pulse shapes. As a byproduct of the acousto-optic effect, light passing through the first order diffraction mode of a fiber-coupled modulator also experiences a frequency shift and beam deflection. This allows the Fiber-Q® products to be used for more than just modulation, resulting in applications outside the laser such as optical heterodyne interferometry. G&H’s fiber optic acousto-optic modulators are designed for low insertion loss, high extinction ratio and excellent return loss. Typical optical performance for the Fiber-Q® series includes: Insertion loss: as low as 2 dB, depending on model Extinction ratio: 50 dB Return loss: 40 dB Polarization extinction ratio: 20 dB (for polarization-maintaining models) G&H has developed the first devices for visible wavelengths from 397 nm to 780 nm to meet the needs of sensing and quantum technology applications. The fast switch rate Fiber-Q® devices enable efficient, high speed optical pulse picking at infrared wavelengths for all-fiber laser systems. Most devices are also offered in 3-port configurations.Applications: Industrial Lasers; Sensing; Scientific Research; Telecommunication; Quantum Technology; Optical Heterodyne Interferometry; Microscopy; Flow Cytometry Series Product Code Wavelength Pigtail Type Rise / Fall Time Operating Frequency Downloads Fiber-Q 1060 nm 150 MHz Non-Hermetic Fiber-Coupled AOM S-M150-0.4C2G-3-F2S 1060 nm SM 30 ns 150 MHz Datasheet Datasheet Datasheet Driver Fiber-Q 1060 nm 200 MHz Non-Hermetic Fiber-Coupled AOM S-M200-0.1C2G-3-F2P 1060 nm SM 10 ns 200 MHz Datasheet  Driver   Driver  Driver Fiber-Q 450 nm 200 MHz S-M200-0.4C2A-3-F2P, S-M200-0.4C2A-3-F2S 450 nm PM, SM 25 ns 200 MHz Datasheet  Driver   Driver  Driver  Fiber-Q 532 nm 200 MHz S-M200-0.4C2C-3-F2P, S-M200-0.4C2C-3-F2S 532 nm PM, SM 25 ns 200 MHz Datasheet  Driver  Driver     Fiber-Q 633 nm 200 MHz Fiber Coupled AOM S-M200-0.4C2E-3-F2P, S-M200-0.4C2E-3-F2S 633 nm PM, SM 25 ns 200 MHz Datasheet  Driver   Driver    Fiber-Q PM 1550 nm, 40 MHz (AMTIR) T-M040-0.5C8J-3-F2P 1550 nm PM 100 ns 40 MHz Datasheet  Driver  Driver  Driver  Fiber-Q 1550 nm 40 MHz (AMTIR) T-M040-0.5C8J-3-F2S 1550 nm SM 100 ns 40 MHz Datasheet Datasheet Datasheet Driver  Fiber-Q PM 2000 nm 80 MHz Hermetic Fiber Coupled AOM T-M080-0.3C2Z-3-F2P 2000 nm PM 100 ns 80 MHz Datasheet  Driver      Fiber-Q 2000 nm 80 MHz Hermetic Fiber Coupled AOM T-M080-0.3C2Z-3-F2S 2000 nm SM 100 ns 80 MHz Datasheet  Driver     Fiber-Q PM 1550nm 80MHz Hermetic Fiber-Coupled AOM T-M080-0.4C2J-3-F2P 1550 nm PM 35 ns 80 MHz Datasheet  Driver     Fiber-Q 1550 nm 80 MHz Hermetic Fiber Coupled AOM T-M080-0.4C2J-3-F2S 1550 nm SM 35 ns 80 MHz Datasheet  Driver     PM Fiber-Q Polarization Maintaining 1550 nm Hermetic Fiber Coupled Acousto-Optic Modulator, 80 MHz (Low Power Consumption) T-M080-0.5C8J-3-F2P 1550 nm PM 100 ns 80 MHz Datasheet  Driver      Fiber-Q 1550 nm Hermetic Fiber Coupled Acousto-Optic Modulator, 80 MHz (Low Power Consumption) T-M080-0.5C8J-3-F2S 1550 nm PM 100 ns 80 MHz Datasheet  Driver      Fiber-Q PM 1550 nm 110 MHz Hermetic Fiber Coupled AOM T-M110-0.2C2J-3-F2P 1550 nm PM 25 ns 110 MHz Datasheet Driver       Fiber-Q 1550 nm 110 MHz Hermetic Fiber Coupled AOM T-M110-0.2C2J-3-F2S 1550 nm SM 25 ns 110 MHz Datasheet  Driver      Fiber-Q PM 1060 nm 150 MHz Hermetic Fiber Coupled AOM T-M150-0.4C2G-3-F2P 1060 nm PM 30 ns 150 MHz Datasheet  Driver     Fiber-Q 1060 nm 150 MHz Hermetic Fiber-Coupled AOM T-M150-0.4C2G-3-F2S 1060 nm SM 30 ns 150 MHz Datasheet  Driver     Fiber-Q, 780 nm, 150 MHz Fiber Coupled AOM T-M150-0.5C2W-3-F2P, T-M150-0.5C2W-3-F2S 780 nm PM, SM 50 ns 150 MHz Datasheet  Driver     Fiber-Q PM 1060 nm 200 MHz Hermetic Fiber Coupled AOM T-M200-0.1C2G-3-F2P 1030 - 1090 nm PM 10 ns 200 MHz Datasheet  Driver Driver     Fiber-Q 1060 nm 200 MHz Fiber Coupled AOM T-M200-0.1C2G-3-F2S 1060 nm SM 10 ns 200 MHz Datasheet  Driver  Driver  Driver  Fiber-Q PM 1550 nm 200 MHz Hermetic Fiber-Coupled AOM T-M200-0.1C2J-3-F2P 1550 nm PM 10 ns 200 MHz Datasheet  Driver Driver     Fiber-Q 1550 nm 200 MHz Hermetic Fiber-Coupled AOM T-M200-0.1C2J-3-F2S 1550 nm SM 10 ns 200 MHz Datasheet  Driver Driver     Fiber-Q 2000 nm (2µm) 250 MHz Fiber Coupled AOM T-M250-0.3C16Z-3-F2P 2000 nm PM 20 ns 250 MHz Datasheet  Driver      Fiber-Q 1060 nm 300 MHz Hermetic Fiber Coupled AOM T-M300-0.1C2G-3-F2P, T-M300-0.1C2G-3-F2S 1060 nm PM, SM 6 ns 300 MHz Datasheet  Driver      Fiber-Q 1550 nm Fiber Coupled Acousto-Optic Modulator T-M300-0.1C16J-3-F2P 1550 nm PM 6 ns 300 MHz Datasheet Driver

Fiber Type Step Index MM, Other; Wavelength 190 to 2400 nm; Sheathing Stainless Steel Monocoil (Bare or PVC Coated); Termination High Power SMA, High Power FD-80Fiberguide’s end capped high power fiber optic assemblies allow the user to achieve higher coupled power into a fiber core by reducing the power density at the air/ silica interface, commonly the point of laser damage. End cap diameters and lengths are offered for select numerical apertures and fiber core sizes but can be easily customized for a variety of fiber types and specialized applications. End capped high power assemblies allow for much higher transmitted powers by reducing the power density to a level below the damage threshold. Their shaped endcap tips can be tailored to specific laser launch conditions and applications. Fiberguide’s proprietary laser polishing process minimizes surface imperfections and maximizes power handling. High Power SMA and D-80 compatible connector options offer superior thermal management while minimizing connector stress for NA conservation. With their epoxy-free cantilevered nose design (available in select versions), Fiberguide’s end capped high power assemblies allow thermal energy to safely dissipate and thus minimize laser and heat damage to surrounding materials Fiberguide offers end capped high power assemblies for a broad range of step index multi mode fibers, including AFS/AFM/AFH/SFS/SFM/SFH all silica optical fiber, AFSH/SFSH hard polymer coat fiber, APC/SPC polymer clad fiber, APCH/SPCH hard clad fiber, AFR/SFR Uniclad™ high power fiber or Solarguide™ solarization resistant fiber. For end capping other fiber types like AGI/ASI anhydrous graded index multi mode fiber or single mode fiber, please get in touch with AMS Technologies’ fiber optic team and discuss the requirements of your solution! For high temperature applications, some fiber types can be aluminium or gold coated on request. Additionally, all fiber types can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.
