A theoretical method was proposed to compensate the burst envelope distortion in a solid-state master-oscillator power-amplifier (MOPA) system operating in burst mode at an intra-burst repetition rate of 40 MHz. Arbitrary envelope shapes were achieved at inter-burst repetition rate of 100 kHz with 40 pulses in the burst, showing excellent agreement with the calculated ones. This is the first demonstration of arbitrary burst envelope without an adaptive feedback loop in a solid-state laser system. The maximum pulse energy of 100 μJ was achieved at inter-burst repetition rate of 40 kHz, with 10 pulses in the burst.
