Abstract
We report a Yb-doped all-fiber laser system generating burst-mode pulses with high energy and high peak power at GHz intra-burst repetition rate. To acquire the uniform burst envelope, a double-pre-compensation structure with an arbitrary waveform laser diode driver and an AOM is utilized for the first time. The synchronous pumping is utilized to the system to reduce the burst repetition rate to 100 Hz and suppress the amplified spontaneous emission (ASE) effect. By adjusting gain of every stage, the uniform envelopes with different output energies can be easily obtained. The intra-burst repetition rate can be tuned from 0.5 to 10 GHz actively modulated by an electro-optic modulator. Optimized by timing control of 8 channels of analog signal and amplified by 7 stages of Yb-doped fiber amplifier,
