摘　　要：报道了一台自启动、长时间稳定、低功率泵浦的自锁模Ｔｉ：蓝宝石激光器和它的高效连续运转的实验结果．实验中观测到５３ｎｍ的光谱带宽（ＦＷＨＭ）．此谱宽可支持１３ｆｓ的激光脉冲．受自相光仪测量仪器的限制．测得的脉宽为２４．６ｆｓ．实际脉冲脉宽可能小于２０ｆｓ．此激光器在自启动锁模、低功率泵浦时．脉宽小于５０ｆｓ．激光器在连续运行时获得０．２Ｗ的泵浦阈值．３５％的斜率效率和１．１Ｗ的激光输出（４Ｗ泵浦）．A self-starting, stable ultrashort-pulsed Ti:sapphire laser with low pump power was demonstrated without additional materials or slit. The laser Produced stable pulses of 24.6 fs. A bandwidth of 53 nm was observed which would correspond to less than 13 fs according to an ideal value of 0.315 for time-bandwidth Product. Pumping threshold of CW operation was 0.2 W, and the output power was up to 1.1 W with an efficiency of 35%.
