Self-Q-switched diode-end-pumped Cr,Nd:YAG laser with polarized output.
Passive Q switching of solid-state lasers is usually accomplished with organic dyes or color centers as the saturable absorber. Dyes, however, have poor thermal stability and tend to degrade rapidly. To operate in cw-pumped lasers, dyes require a circulation system. Color centers, such as the color-center LiF crystal, -3 exhibit a fading phenomenon that may limit the period of reliable operatio...
متن کاملSelf-starting self-mode-locked femtosecond diode-pumped Cr:LiSAF laser.
We describe a diode-pumped Kerr-lens mode-locked Cr(3+):LiSrAlF(6) laser that produces 50 mW of 70-fs pulses in the 820-890-nm range when pumped by two red diodes of 400 mW each. By using a lower-transmission output coupler we have demonstrated for the first time to our knowledge a self-starting regime with an output power of 10 mW and 55-fs pulses.
متن کاملA Passively Q-Switched, CW-Pumped Fe:ZnSe Laser
We report the demonstration of high-average-power passively Q-switched laser oscillation from Fe2+ ions in zinc selenide. A semiconductor saturable absorber mirror was used as a passive Q-switch element. Using a 60% R outcoupler, the pump-limited output power was 515 mW. The spectral center of the laser was 4045 nm. The pulse repetition frequency (PRF) at maximum power was ∼850 kHz with a corre...
متن کاملPassively Q-switched diode-pumped Cr:YAG/Nd:GdVO4 monolithic microchip laser
the realization of high repetition rate passively Q-switched monolithic microlaser is a challenge since a decade. To achieve this goal, we report here on the first passively Q-switched diode-pumped microchip laser based on the association of a Nd:GdVO4 crystal and a Cr:YAG saturable absorber. The monolithic design consists of 1 mm long 1% doped Nd:GdVO4 optically contacted on a 0.4 mm long Cr:Y...
متن کاملPassively Q-switched diode-pumped Er:YAG solid-state laser.
We demonstrated laser operation of a passively Q-switched diode-pumped Er:YAG solid-state laser emitting at 1645 or 1617 nm depending on the initial transmission of the Cr:ZnSe saturable absorber. The crystal emitted up to 10 W at 1645 nm and up to 8 W at 1617 nm in CW mode while pumped with 65 W of incident pump power at 1533 nm. In passive Q-switched mode with 40 W of incident power, a Cr:ZnS...
