采用半导体饱和吸收反射镜的低阈值自启动飞秒掺钛蓝宝石激光器
Self-Starting Femtosecond Ti:Sapphire Laser with Low-Threshold Pump
摘要
报道了采用紧聚焦的谐振腔设计并结合半导体可饱和吸收反射镜所研制的低阈值自启动克尔透镜掺钛蓝宝石激光器.在采用透过率为3%和12%输出耦合镜的情况下,分别获得了阈值低至390 mW和600 mW的稳定锁模脉冲输出.结果表明:对于12%的输出耦合,在1.2 w抽运时能够产生17fs的最短脉宽,对应的光谱宽度为47 nm,输出平均功率为114 mW.
Abstract
A low-threshold self-starting Kerr-lens mode-locked Ti:sapphire laser was demonstrated by use of a tight focusing cavity design and a semiconductor saturable-absorber mirror (SESAM). With a 3% and a 12% output couplers, mode-locking thresholds as low as 390 mW and 600 mW weve achieved, respectively. Stable femtosecond laser pulses with average power of 114 mW were generated for pump power at 1.2 W, which correspond to a typical duration of 17 fs and bandwidth of 47 nm.
