We have generated picosecond optical pulses with a peak power greater than 300W at 1 GHz repetition at a blue-violet wavelength using a GaInN-based master oscillator power amplifier. The optical pulses were generated by a mode-locked laser diode incorporating the flared waveguide structure for the increased active region volume to obtain higher output power. The pulses were effectively amplified by the semiconductor optical amplifier with reduced optical confinement factor to high peak power.
