Solid-State Lasers Mode-Locked by Linear and Nonlinear Frequency Shiftf-phase modulation,. nonlinear optical Kerr effect. and self-focusing.. An extremely short pulses have been achieved due to the femtosecond response of these third-order nonlinearities. It was shown that the start of ultra-short pulse generation may be provided by external disturbances of a laser sy

Parametric Nonlinear Mirror in Actively Mode-Locked Nd:YAG Laser with Negative Feedback Controld-state lasers. The intracavity second harmonic generation (SHG) nonlinear mirror (NLM). is one of such devices which has been intensively investigated as a mode- locker both for pulsed. and cw lasers.. A stable NLM operation providing the reliable formation or shortening of light pulses takes place

Hidden Mechanism for Mode Locking Solid-State Lasers by Use of a Slow Off-Resonant Saturable Absorbeelf-starting 34fs pulses in a Ti:sapphire laser. as well as 90fs pulses in a diode pumped Cr:LiSAF laser.. These experimental findings can hardly be explained by the common theoretical understanding of passive mode locking in solid-state lasers which requires a fast saturable loss for stable pulse g

OCTO

Tunable UV Picosecond Pulse Generation Using Fast Spectral Evolution of Low-Q Short Dye Laser Oscill. In recent years numerous approaches have been made to generate UV ultrashort pulses, including sum or difference-frequency mixing in nonlinear optic crystals and noble gases, third-harmonic generation in noble gases and anti-stock Raman shifting.. The existing commercially available UV ultrashort
