Pulse-Shaping of Nanosecond Broadband KrF Laser
Pulse-shaping of nanosecond broadband KrF laser is studied in this paper. Short pulse is obtained through the stimulated Brillouin scattering (SBS) pulse compression, and then the pulse-shaping is realized by using the pulses-stacking. According to the amplification of stacking-pulses in KrF laser amplifier, KrF laser amplifier has great influence on the shape of stacking-pulse. Through adjusting the shape of stacking-pulse, the anticipated shaped pulse can be gained after amplification. The energy of shaped-pulse reaches 50mJ after once amplification, and reaches 300mJ after twice amplifications. The theoretical analysis agrees well with the experimental results. The results show that the combined scheme of pulse-stacking and the amplification of amplifier have strong ability of pulse-shaping.
