一种可用受激布里渊效应选脉冲的自滤波被动锁模激光器

Generation of Single M-L Pulse from a Novel Passively Mode-locked SFUR Laser Using SBS

本文用特殊设计的、能自准直输出激光束、满足空间自滤波条件的小孔光柱，实现了被动脉冲锁模Nd：YAG激光器的自滤波振荡。销模脉冲序列能量～70mJ，序列中只包含3～4个脉冲，脉冲宽度为≤40ps，光束发散角＜1mrad。用CCl4溶液受激布里渊后向散射阈值效应，成功地实现了用全被动方法获得锁模单脉冲输出。

A novel unstable resonator configuration with a special designed self-filteringAperture, loaded with Nd:YAG, was used for generating passively mode-locked picosecondPulses. Typical figures are:～70mJ pulses energy output, total 3 pulses in the ML Pulse train,≤40ps pulse duration, and＜1mrad divergence beam. Single mode-locked pulse has been obtained by stimulated BRILLOUIN scatting in CCl4 solution.
