Seed Laser Module
3S Photonics has unveiled a 500-mW continuous-wave version of its 1064-nm seed laser module for fibre lasers. Providing a peak operating current of up to 1.7 A with 1-μs/500-kHz pulses, it operates from 1050 to 1070 nm, delivers short-pulse operation of 5 to 500 ns and offers a heat sink temperature up to 50 °C. Housed in a low-profile hermetically sealed 14-pin butterfly package, the system includes an internal thermoelectric cooler, a thermistor and a back-facet monitor photodiode. It also features a polarization-maintaining single-mode fibre pigtail and is RoHS-compliant.
