我们在国内首先研制成功波长为800nm附近布拉格反射镜型半导体可饱和吸收镜。用布拉格反射镜型半导体可饱和吸收镜作为自启动装置,我们实现了氩离子激光器泵浦的钛宝石激光器被动连续锁模,获得了连续锁模脉冲序列,重复频率在100 MHz到200 MHz。
We first developed in the country with a wavelength of 800nm near Bragg reflector type semiconductor saturable absorption mirror. Using a Bragg mirror-type saturable absorption mirror as a self-starting device, we achieved a passive mode-locked mode with a Ti-sapphire laser pumped by an argon-ion laser and obtained a continuously mode-locked pulse sequence with a repetition rate of 100 MHz to 200 MHz.
