摘　　要：利用国内生长的低损耗双量子阱结构的可饱和布拉格反射器在掺钛蓝宝石激光器中实现了可饱和吸收体被动锁模、孤子锁模和KLM锁模状态的自启动稳定运转.当抽运功率为4.5W时,用啁啾镜进行色散补偿,获得了18fs的KLM锁模脉冲,输出功率为150mW.Stable self-starting mode-locking states in a compact Ti： quantum-well and low temperature and surface state hybrid sapphire laser incorporating a home-made SBR with low loss double 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.
