Femtosecond passively mode-locked Ti:Al sub 2 O sub 3 laser with a nonlinear external cavity
Technical Report
·
OSTI ID:7004597
Nonlinear-optical feedback that uses an external coupled cavity is a powerful technique for enhancing the performance of mode-locked lasers. Ultrashort pulses are generated in a Titanium:Aluminum Oxide laser by using a coupled nonlinear external cavity. The external cavity uses self-phase modulation in an optical fiber to achieve passive mode locking without the need for synchronous pumping or acousto-optic modulation. A stable train of chirped 1.4-psec pulses is generated. After dispersive compensation, pulses as short as 200 fsec are obtained.
