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．
The design principle of a new cross-mode-locked multi-wavelength Ti: sapphire femtosecond laser is reported. The laser can simultaneously produce two or three columns of femtosecond pulses. The dual-wavelength pulsed tunings with durations as short as 25 fs are tuned between 755 and 848 nm, with a synchronization accuracy of about 10 fs. Three-wavelength pulse duration of less than 100fs, the center wavelength were 755nm, 800nm and 830nm.
