Pulse shortening in a Nd:glass laser by gain reshaping and soliton formation.
We demonstrate that intracavity filtering and soliton formation in actively mode-locked lasers can lead to pulse shortening by as much as a factor of 30. Pulses as short as 310 fs have been generated from a Nd:glass laser that is mode locked only by an acousto-optic modulator.
