A multi-wavelength tunable self-mode-locked Ti:sapphire laser has beenconstructed that synchronously gcncratcs femtosecond pulse trains at two independentwavelength regions or three. Pulses as short as 48 fs with a 70 mW average output powerand a central tvavelength separation adjustable between 26 nm and 49 nm have beenproduced by using correspondent apertures or slits. This laser can be tuned from 750 nm to 830 nm.
