Synchronously pumped, femtosecond dye laser insensitive to cavity-length variations of up to 15 microm.
A synchronously pumped, hybridly mode-locked, antiresonant-ring dye laser that is insensitive to cavity-length variations of up to 15 microm is described. At a cavity length that is 70-80 microm shorter than the synchronous cavity length this laser generates stable pulses as short as 55 fsec, with a pulse width of 65 fsec being typical (assuming a sech(2) pulse shape). No evidence for colliding-pulse mode-locking effects is observed.
