波长脉宽可调的ps钛宝石自锁模激光器

Wavelength and Pulse Duration Tunable ps Self Mode Locked Ti:Sapphire Laser

利用Ｇｉｒｅｓ－Ｔｏｕｒｎｏｉｓ干涉仪提供负群速度色散补偿钛宝石棒产生的正色散，以获得稳定的ｐｓ自锁模脉冲。腔内插入双折射滤光片实现波长调谐。这种用Ｇ－Ｔ干涉仪代替全反镜的ｐｓ钛宝石自锁模激光器具有插入损耗小，脉宽可调。

We use Gires Tournois interferometer as a means of providing negative GVD to compensate positive GVD of Ti:sapphire rod. Stable ps self mode locked pulse has been obtained. Birefrigent filter is used in the cavity to realized wavelength tunable. This kind of ps self mode locked Ti:sapphire laser which uses G T interferometer as a high reflective mirror is of low insertion loss, pulse duration and wavelength tunable.
