Abstract

We demonstrate 1.54 W of laser emission at 905 nm from a fully fiber-based polarization-maintained master oscillator power amplifier (MOPA). The laser system comprises a directly modulated Fabry-Perot laser diode emitting at 905 nm, which is subsequently amplified by a three-stage pre-amplifier and a main amplifier. The system achieved an output energy of 0.15 mJ at a repetition frequency of 10 kHz with a pulse width of 20 ns.
