Abstract

Using a single-stage all-semiconductor master oscillator-power amplifier system, consisting of a Q-switched distributed Bragg reflector laser as master oscillator and a tapered power amplifier, we generate laser pulses with a length of 80 ps and a peak power of 50 W. The spectral width is less than 1 nm around a center wavelength of 1066 nm. The background of the amplified spontaneous emission is significantly reduced due to a pulsed, instead of continuous-wave operation of the amplifier. The current pulses have a width of approximately 10 ns and a repetition frequency of 1.25 MHz.
