Studies on the Compression of Electrooptical Q-switched Cr∶LiSAF Laser Pulse Width by SBS Phase Conjugator
【摘要】 在抽运能量一定的条件下 ,采用强聚焦短焦距透镜提高焦点处的光功率密度 ,将Cr∶LiSAF电光调Q激光器的输出脉冲聚焦于装有CS2 介质的受激布里渊散射 (SBS)池中 ,实现了宽线宽、多横模Cr∶LiSAF激光脉冲的后向SBS ,并观察到对激光脉宽的有效压缩。
【Abstract】 Under the condition of given pump laser energy, using a lens with short focal length to focus the Cr∶LiSAF electrooptical Q- switched laser pulses into CS 2 SBS-cell, the backward SBS scattering of broad-band and multi-transverse-mode Cr∶LiSAF laser pulses is realized, and the effective pulse width′s compression is observed.
