小型飞秒激光脉冲放大器

A compact femtosecond regenerative laser amplifier

在放大器谐振腔内插入一对棱镜 ,使飞秒脉冲信号边放大 ,边展宽。既防止了强光的自聚焦效应 ,又减小了整个放大器占用空间。输出光再经过另一对棱镜压缩 ,得到的脉宽小于 10 0fs,重复率 10kHz,平均功率达到0 .2W。

A compact all-solid-state Ti∶sapphire regenerative laser amplifier without pre-pulse stretching has been developed. Laser pulses are stretched two times every round trip by a pair of prisms inside the cavity. The re-compressed 100fs pulses at 10kHz repetition rates are generated . The average output power is more than 0.2W.
