Paper Abstract

We demonstrate environmental test results of a compact high-power master oscillator (MO) power amplifier (PA) laser module emitting near 1064 nm. The module is micro-integrated on a footprint of 50 × 10mm2, features an output power of 1 W, an intrinsic linewidth of 3.6 kHz, and a FWHM linewidth of 100 kHz. Results of lifetime tests and vibrational tests will be presented. Furthermore, we introduce tuning characteristics of a distributed Bragg reflector laser that can be used as a master oscillator. 2 nm of fast tuneability is realized by placing on-chip heaters close to the Bragg grating.
