摘要：

We　report　on　high　power　nanosecond-pulsed　polarization　maintaining　(PM)　master　oscillator　power　amplifier　(MOPA)　system　seeded　by　a　semiconductor　laser　diode　at　2　pm　incorporating　arbitrary　pulse-shaping　technique.　By　pre-compensating　the　effects　of　gain　saturation　of　the　power　amplifier,　we　obtain　the　right-angled　trapezium,　rectangular,　＇M＇-shaped　and　＇h＇-shaped　pulses　in　240　W　average　power　level　with　240　μJ　pulse　energy,　respectively.　©　2016　OSA.
