Abstract: A semiconductor seed laser was designed for master optical parameter amplifier（MOPA）. A high-speed and high-current driving module and an arbitrary waveform generator were developed. A semiconductor pulse seed laser, whose peak power is more than 200 mW, pulse width is from 1.5ns to 1μs, and pulse frequency is adjustable from 1kHz to 1MHz, was obtained by using a 1.064μm QW-DFB high-power diode laser.
