Self-starting mode-locked femtosecond Ti: sapphire laser using saturable Bragg reflector(SBR)
利用SBR实现自启动锁模钛宝石飞秒激光脉冲的产生

Stable self-starting mode-locking states in a compact Ti: sapphire laser incorporating a home-made SBR with low loss double quantum-well and low temperature and surface state hybrid absorber are investigated experimentally. The three mode-locking states, i.e. the passive mode-locking with a saturable absorber, the solition mode-locking and the Kerr-lens mode-locking have been successfully demonstrated. In this laser, chirped mirrors are used for dispersion compensation, and the 18 fs pulses are produced from the Kerr-lens mode-locking at 4.5W pump power, and output power is 150mW.
