摘要

采用3mm长的钛宝石短棒和改进的非对称Z型折叠腔结构进行自锁模实验

采用石英棱镜对作为腔内色散补偿元件

在氩离子激光器输出5W泵浦下

实现低阈值泵浦自锁模运转。在腔内不加任何调制元件的情况下实现软光阑锁模

获得最短脉冲15fs

光谱宽度80nm

输出平均功率400mW.同时以此钛宝石激光器作为振荡器采用12mm长的钻宝石棒进行飞秒啁啾脉冲再生放大实验

获得重复率5kHz

单脉冲能量166ttJ的结果

放大脉冲光谱宽度为26nm.

Abstract

Making Self Mode Locking experiment using the 3 mrn Ti:sapphire short rod and the improved asymmetric Z shape folding configuration

with quartz prisms as dispersion compensation element

we achieve low threshold self Mode Locking operation with 5 W pumping Argon power and soft-aperture mode Locking without any modulating element. The pulse duration is 15 fs with 80 ntn spectrum bandwidth. The X00 mW average power is obtained. Using the SML Ti:sapphire laser as oscillator

the Ti:sapphire ferntosecond chirping pulse regenerative amplification is done. The amplified pulse repetition is 5 kHz

the single pulse energy is 165J.The 26 nm bandwidth supporting 26 fs is obtained.
