Title

Femtosecond pulses from the novel solid-state laser source Cr : LiSGaF

Abstract

Efficient high-power TEM00 cw laser operation of Cr : LiSGaF laser at Kr+-laser pumping is demonstrated. Results of spectroscopic and laser performance analysis, taking into account upconversion and excited-state absorbtion, are presented and used for the optimization of this laser yielding more than 900 mW output power. Different setups for Kerr-lens mode locking, aiming at two goals simultaneously - high output power and short pulse duration - are analyzed and tested. The most simple KLM mode-locked Cr : LiSGaF laser could be realized, containing no intracavity prisms. This laser produced stable, near-transform-limited 44-fs pulses with an output power of 200 mW, tunable between 833 and 857 nm. Low-loss Gires - Tournois (GT) structured dielectric mirrors were used for dispersion control. The preference of such GT-type mirrors over chirped mirrors is discussed in detail. The shortest near-transform-limited pulses achieved so far in a GT-mirror dispersion-controlled resonator are 37 fs. Copyright © 1997 by MANK Hayka/Interperiodica Publishing.
