Abstract

We present a method of the generation of sub-100 ps pulses with an all-semiconductor master oscillator–power amplifier (MOPA) system, consisting of a three section distributed Bragg reflector (DBR) laser as MO and a two section tapered PA. The pulses generated by the gain-switched DBR laser are first shortened by the ridge-waveguide input section of the PA acting as a saturable absorber and then amplified by the tapered gain region section. We generate laser pulses with a minimum duration of 35 ps and a peak power of more than 65 W. The spectral width is less than 0.25 nm around a center wavelength of 1063 nm.
