多波长单腔型自锁模飞秒钛宝石激光器的运转特性

OPERATING CHARACTERISTICS OF MULTI-WAVELENGTHSELF-MODE-LOCKED FEMTOSECOND Ti:SAPPHIRE LASER WITH A SINGLE CAVITY

在自锁模飞秒钛宝石激光器运转状态不变的条件下，仅仅改变所加光阑，便可获得三波长或双波长的飞秒光脉冲运转．在此基础上，我们比较了这两种运转状态下激光器输出脉冲的脉宽，啁啾、中心波长间距和输出功率的差异．给出了在不同条件下运转时的双波长激光器的输出特性．讨论了多波长运转时的一些规律．

Three-wavelength or dual-wavelength self-mode-locked Ti:sapphire laser can be obtained by introducing different diaphragm in the cavity at the same conditions of the operating states of the self-mode-locked laser.The output characteristics of the three-wavelength and the dual-wavelength operations are checked,these characteristics include pulse width,chirp,output power,and the central wavelength separation. This paper also reports the output parameters of the dual-wavelength Ti:sapphire laser which works in different conditions. Finally,some regulars are discussed for themulti-wavelength operating states.
