摘要
报道了一种新的交叉锁模多波长钛宝石飞秒激光器的设计原理．该激光器能够同步产生两列或三列飞秒光脉冲．持续期短到２５ｆｓ的双波长脉冲调谐在７５５—８４８ｎｍ之间，同步精度约１０ｆｓ．三波长脉冲持续期小于１００ｆｓ，中心波长分别为７５５ｎｍ，８００ｎｍ及８３０ｎｍ．
We report on a novel design of a multi-wavelength Ti:sapphire femtosecond laser using a cross-mode-locking technique. This laser can synchronously generate two or three train of femtosecond pulses. The two-wavelength pulses have durations as short as 25fs tunable between 755nm to 848nm, and their synchronization precision is approximately 10fs. The three wave-length pulses of sub-100fs duration are generated at central wave lengths 755nm, 800nm and 830nm, respectively.
