1W semiconductor based laser module with a narrow linewidth emitting near 1064nm

We demonstrate 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 x 10mm2. The oscillator is a distributed Bragg reflector laser optimized for narrow linewidth operation. The amplifier consists of a ridge waveguide entry and a tapered section. The module features stable single-mode narrow linewidth emission at an output power of 1W and can be tuned mode-hop free by 450GHz.
