Product information "TETRA DPSS Lasers"
Four wavelengths: 532 nm, 555 nm, 579 nm, 606 nm; pulse-by-pulse switchable with 2 kHz; Pulse Energy 20 µJ; Pulse Length <5 ns
The diode-pumped solid-state laser TETRA emits very short laser pulses (< 5 ns) of high energy (up to 20 µJ) with four wavelengths in the visible range, which are particularly suitable for multispectral photoacoustic imaging. Using sophisticated technology, the TETRA laser can switch from pulse to pulse between these four wavelengths with a very high pulse repetition frequency of 2 kHz.
Utilizing the Raman effect and the light of a 532 nm pump laser, the TETRA laser additionally generates the wavelengths 555 nm, 579 nm and 606 nm. A tunable optical filter separates the four wavelengths and routes one wavelength at a time to the optical output of the unit at a switching frequency of up to 2 kHz. This makes TETRA about ten times faster than tunable lasers based on OPOs (Optical Parametric Oscillators) – typical frequencies of such OPO systems range from 100 Hz to 200 Hz – while also being considerably more cost-effective.
The wavelengths emitted by TETRA are well matched to the absorption curves of many blood components, making the laser particularly suitable for photoacoustic tomography in biomedicine. We have equipped TETRA with a number of features to meet the requirements of medical safety standards for use in clinical environments. For instance a fast, fault-tolerant shutter at the laser output interrupts the beam in the event of a fault in the shortest possible time in order to avoid any hazards to a patient.

Automated, Mid-span; Window Strip Length 2-150 mm; Fiber Coating Diameter ≤1,000 µm; Fiber Cladding 125-400 µm; Pulling Speed 20-100 mm/min The AutoStrip II is designed for fast, chemical free window stripping of optical fibers. Utilizing SAE Technologies’ patented “Burst Technology™”, this system accomplishes the often difficult task of window stripping fibers with acrylate coating diameters up to 1,000 µm. The AutoStrip II automated, mid-span window stripping unit meets the need for variable window strip lengths at high strength and ultra cleanliness. The proven Burst Technology™ method instantly vaporizes the fiber coating. The result is a clean, stripped fiber at substantially higher strength than any mechanical stripping method. The fiber is free of debris at 400x magnification. Equipped with a built-in, high-force fiber tensile tester, the AutoStrip II system can pull the fiber up to 20 N (235 kpsi). To ensure high quality, repeatability and high production yield, all critical processes and parameters such as stripping distance, burst temperature, burst speed, and strength test are controlled automatically by a built-in microprocessor. The AutoStrip II can be used as a stand-alone unit or integrated into different sub-systems. The use of chemicals for high-strength fiber stripping is now a thing of the past! Key Features: Chemical-Free (No Cleaning or Stripping Chemicals Required) Easy, Low-maintenance Bench-top Design Fast Cycle Time & High First-pass Yield Accommodates Acrylate Coating Fiber Diameters up to 600 μm (Custom Nozzles up to 1,000 μm) Variable Window Strip Lengths From 2 up to 150 mm Fiber Cladding: 125 to 400 μm Fiber Strength: Typical >35 N on 125 μm Fiber Fiber Cleanliness: Free of Debris at 400x Magnification Built-in High-force Linear Tensile Tester, Tensile Strength: 0 to 20 N Pulling Speed: 20 to 100 mm/min, Hold Time: 0 to 5 s Power Supply: 115 to 230 V AC Compressed Air: External Compressor, 95 psi - 5 SCFM Flow PC Interface: RS232C Software-adjustable Parameters Automated Fiber Clamps Built-in Graphical LCD Control Storage of up to 10 Programs Dimensions: 465 x 315 x 225 mm Application: Automated, Mid-span Window Stripping of Optical Fibers With Acrylate Coating Diameters up to 1,000 µm

1700-1750 nm; Output Energy ≤50 µJ; Repetition Rate ≤10 kHz; Pulse Width 2-5 ns; Pump Laser and OPO in Single Rugged Housing Our 170P0-1-50-S MID-IR tunable OPO (optical parametric oscillator) source combines pump laser and OPO in a single, rugged housing and generates laser pulses in the mid-infrared (MID-IR) range around 1700 nm – the applications for such wavelengths are mainly in the field of photoacoustic imaging, in addition to gas chromatography and other analysis tasks. The OPO’s wavelength can be tuned in an extended range from 1700 nm to 1750 nm. Other wavelength ranges (e.g. 1500 nm to 2000 nm) are available on demand. Using an electro-optical Q-switch, very short pulses with typical pulse widths of 2 ns to 5 ns are generated. If different wavelengths, repetition rates, pulse energies or pulse widths is what you are looking for, the laser experts at Elforlight (an AMS Company) are happy to specify, design and manufacture your customized OPO solution.
