説明

We demonstrated reflect-type pulse shaping of high-power femtosecond pulses from a Ti: sapphire regenerativeamplification system that generates 4.0-μJ pulses of less than 70-fs pulsewidth at a 250-kHz repetition ratewith an average power of 1.0W. The PAL-SLM (Parallel Aligned nematic Liquid crystal Spatial Light Modulator) contained in our pulse shaping apparatus was evaluated and was able to modulate high peak powerpulses up to 2.4×107W. As a result, the pulse shaping system was used to generate high-power double pulses, as was confirmed by FROG (Frequency Resolved Optical Gating).
