摘　　要：用多块ＢＢＯ晶体对钛宝石激光进行宽带三倍频，比通常的两块晶体的方法效率上有所提高，实验研究了三倍频光的时间和空间特性，并从理论上分析了这种方法在激光带宽和效率等方面的优点，为ＩＣＦ提高一种新的三倍频技术。Third harmonic generation of broad-band Ti:sapphire laser was obtained with multicystal, this equipment can improved the efficiency and the accept bandwidth. The efficiency curve, the temporal, and the spatial graph of the THG have been shown. The result was analysised with the broad-band nonlinear equation. The accept bandwidth and the leave-off angle were also studied.
