760-1083 nm; Typ. Linewidth 0.6 MHz; Output Power 6-150 mW CW; Threshold Current ≤70 mA; Slope Efficiency 0.7 W/A; Side Mode Suppression Ratio ≥30 dBToptica eagleyard’s DFB series of distributed feedback (DFB) laser diodes features a built-in wavelength-selective grating stabilizing the wavelength. The DFB series’ entire resonator consists of a periodic structure. Thus, the devices operate on a single resonator mode emitting quasi-monochromatic radiation with a very small line width and low phase noise. The lasers can have very low-intensity noise because of the lack of mode partition noise. Due to the Gaussian mode the output is diffraction-limited.The choice of a distributed feedback design instead of a similar distributed Bragg grating (DBR) structure enables even a broader smooth tuning range around the operational point without the risk of experiencing spectral issues known as mode-hops, as these are given by design of a DBR diode, making the latter less suitable for the needs of atom spectroscopy.Special variants are available – two versions are intended to be used as seed lasers for pulsed fiber lasers, while other variants aim at oxygen detection as the emission wavelength of these laser diodes match with the strong absorption lines of oxygen at 760 nm and 764 nm while wavelength tuning around one of these absorption lines is possible.Further variants are especially suitable for spectroscopy with mode‐hop free operation and small linewidth guaranteed at the specified target wavelength for spectroscopic applications – these laser diodes are reaching the target wavelength by temperature tuning and allow wavelength tuning around this target wavelength.External backreflections may disturb the spectrum of these laser diodes, so the use of butterfly (BFW01) or TOC03 packages and effective optical isolation is recommended for spectroscopic applications requiring absolutely mode‐hop‐free tuning. Finally, special tunable variants with integrated optical isolators are available, enabling a wide mode‐hop free tuning range given by the specified operating temperature range and the specified power range.Key Features:Single Frequency ModeHigh Side Mode Suppression > 50 dBNarrow Linewidth <1 MHzPulse Width 1 to 50 nsPeak Power up to 500 mWRepetition Rate up to 1 MHzSMSR >35 dBProductWavelengthOutput PowerSpecificsDFB-0760-00012-1500-BFY12-0005760 nm12 mWoxygen detection, spectroscopy, metrologyDFB-0760-00040-1500-BFW01-0005760 nm40 mWoxygen detection with collimatorDFB-0760-00040-1500-TOV01-0005760 nm40 mWoxygen detection VCSEL replacementDFB-0760-00040-1500-TOC03-0005760 nm40 mWoxygen detectionDFB-0780-00020-1500-BFY12-0005780 nm20 mWoxygen detection,spectroscopy: Rb D2DFB-0780-00040-1500-BFY02-0000780 nm40 mWbasic variant with PM fiberDFB-0780-00040-1500-BFY02-0002780 nm40 mWtunable with PM fiberDFB-0780-00040-1500-BFW11-0005780 nm40 mWspectroscopy: Rb D2 with isolator and collimatorDFB-0780-00080-1500-TOV01-0005780 nm80 mWspectroscopy: Rb D2DFB-0780-00080-1500-BFW01-0002780 nm80 mWtunable with collimatorDFB-0780-00080-1500-BFW01-0005780 nm80 mWspectroscopy: Rb D2 with collimatorDFB-0780-00080-1500-TOC03-0000780 nm80 mWbasic variantDFB-0780-00080-1500-TOC03-0002780 nm80 mWtunableDFB-0780-00080-1500-TOC03-0005780 nm80 mWspectroscopy: Rb D2DFB-0785-00040-1500-BFY02-0000785 nm40 mWbasic variant with PM fiberDFB-0785-00040-1500-BFY02-0002785 nm40 mWtunable with PM fiberDFB-0785-00100-1500-TOV01-0000785 nm100 mWbasic variantDFB-0795-00015-1500-BFY12-0005795 nm15 mWspectroscopy: Rb D1 lineDFB-0795-00040-1500-BFW11-0005795 nm40 mWspectroscopy: Rb D1 with isolator and collimatorDFB-0795-00080-1500-BFW01-0005795 nm80 mWspectroscopy: Rb D1 with collimatorDFB-0852-00015-1500-BFY12-0005852 nm15 mWspectroscopy: Cs D2 DFB-0852-00050-1500-BFY02-0000852 nm50 mWbasic variant with PM fiberDFB-0852-00050-1500-BFY02-0002852 nm50 mWtunable with PM fiberDFB-0852-00100-1500-BFW01-0002852 nm100 mWtunable with collimatorDFB-0852-00100-1500-BFW01-0005852 nm100 mWspectroscopy: CS D2 with collimatorDFB-0852-00150-1500-TOC03-0000852 nm150 mWbasic variantDFB-0852-00150-1500-TOC03-0002852 nm150 mWtunableDFB-0852-00150-1500-TOC03-0005852 nm150 mWspectroscopy: Cs D2DFB-0895-00050-1500-TOV01-0005895 nm50 mWspectroscopy: Cs D1DFB-0935-00080-1500-TOC03-0004935 nm80 mWspectroscopy: YbDFB-1030-00500-1500-BFY02-00101030 nm500 mWseed laser (pulsed mode) with PM fiberDFB-1064-00025-1500-BFY12-00021064 nm25 mWtunable with isolator and PM fiberDFB-1064-00040-1500-BFY02-00001064 nm40 mWbasic variant with PM fiberDFB-1064-00040-1500-BFY02-00021064 nm40 mWtunable with PM fiberDFB-1064-00080-1500-TOC03-00001064 nm80 mWbasic variantDFB-1064-00080-1500-TOC03-00021064 nm80 mWtunableDFB-1064-00500-1500-BFY02-00101064 nm500 mWseed laser (pulsed mode) with PM fiberDFB-1083-00025-1500-BFY12-00021083 nm25 mWtunable with isolator and PM fiberDFB-1083-00080-1500-TOC03-00021083 nm80 mW Applications: Interferometry, Laser Doppler Velocimetry and Vibrometry; Cold Atoms; Optically Pumped Atom Clocks; Quantum Optics; THz Generation, Raman Spectroscopy; Cs- ,Rb- , K- Spectroscopy; Seed Laser for LIDAR SystemsPlease note that TOPTICA eagleyard products are not availble from us in Denmark, Finland, Iceland, Norway, and Sweden.

Catalog series OP-6721 VIPA etalons are available with dimensions of 22.0 x 24.0 mm and 18 x 18 mm aperture. Free spectral range (FSR) values are 15 GHz (0.5/cm), 30 GHz (1/cm) and 60 GHz (2/cm), each available with nine different finesse values from 56 to 100, resulting in nine different wavelength ranges from 415 to 1700 nm. Wavelength range, thickness, finesse, FSR and other design details of OP-6721 and OP-7553 series VIPAs are also available based on customer requirements. For the OP-6271 series, a dedicated protective aluminium mount is available that enables mounting the VIPA in a standard 50.8 mm (2”) diameter optic holder – its price includes cementing of the VIPA to the mount at the supplier. A VIPA (Virtually Imaged Phase Array) is a special type of Fabry-Perot etalon with a built-in transmission window so the beam can sneak in past the first reflector and effectively commence the multiple reflections and constructive and destructive interference from inside the etalon. By changing the first reflector to a full 100% high reflector, the beam can only exit in transmission, this effectively creates an etalon with ~100% transmission. VIPAs are made with three distinct coatings, carefully selected to match the wavelength range of interest: One surface of a VIPA has an anti-reflection coated section adjacent to a high reflector. The opposite surface is coated with a partially transmitting mirror. Light is introduced into the VIPA at a small angle on the AR coated area. The VIPA is tilted so that the portion reflected from the partial reflector is fully incident on the high reflectance zone of the input surface. A single input beam is converted to a series of parallel output beams of gradually decreasing intensity. These beams will constructively interfere at an angle that depends on the wavelength. Placing a lens between the VIPA and an array detector (CCD or similar) allows recording of a spectrum of the input light. Each subsequent beam has a precise increase in phase and fixed lateral displacement, hence “phase array”. LightMachinery is the world leader in high-accuracy VIPA fabrication, and VIPAs are at the core of many of LightMachinery’s spectrometers. Several parameters define the performance of a VIPA. The first is its optical thickness (OPD) – the free spectral range (FSR) is approximately c/OPD. Analogous to a regular etalon, the angular dispersion of the VIPA output will repeat every time the input frequency (or wavelength) increases by 1 FSR. The second important parameter is the reflectance of the output mirror. In principle, a higher reflectance mirror will increase the resolving power of the VIPA. Light Machinery has optimized the partial reflectivity for each wavelength range to maximize finesse; finesse greater than 100 has been achieved for VIS/NIR applications. In other words, it will be possible to distinguish wavelengths separated by 1/100th of the FSR. The third important parameter is the internal angle of the light traveling through the VIPA. Smaller angles increase the angular dispersion, and a narrower transition between the antireflection coating and the high reflector enables a smaller angle. LightMachinery’s VIPAs have a transition width of only 2 to 3 µm, which enables operation of the VIPA at a very small angle. This reduction in angle improves resolution and contrast compared to what was previously possible. Sometimes you need something special – if you are looking for a customized VIPA etalon that exactly meets your specific requirements (e.g. different substrate materials like Silicon, etc.), please get in touch with the AMS Technologies etalon experts. Our supplier LightMachinery is extremely experienced with specifying, designing and manufacturing custom etalons using the company’s patented fluid jet polishing (FJP) technology. We are looking forward to discussing your customized etalon solution! Fluid jet polishing (FJP) systems use a fine stream of slurry to accurately remove nanometers of material from an optical surface. Many years of refining this computer controlled polishing technology have enabled LightMachinery to use FJP for the adjustment of the shape and flatness of optical components such as etalon mirrors to within a few nanometers as well as the production of very thin components such as wafers and thin etalons that are impossible to accurately polish using conventional technology.
