摘要
A pulse semiconductor laser modulated by arbitrary shaping electrical waveform is produced and the generated optical pulse can be taken as the seed resource for high-power laser facilities.Based on ultrawide band microwave device and microstrip line transmission delay application, an all-solid-state circuit for generating arbitrary modulation pulse to modulate the semiconductor laser is fabricated. For improving the semiconductor laser power, the output laser pulse is sent into erbium-doped fiber master oscillator power amplifier architecture for amplification. In the experiment, the output laser pulse can be arbitrarily adjusted at 1547.9 nm center wavelength, less than 10 ns duration, lower than 100 kHz repetition rate, and 330 ps time domain adjustment.
