【Abstract】 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.更多还原
