Diode Pumped Yb-lasers Q-switched by V:YAG Saturable Absorber

Popis výsledku v původním jazyce

V:YAG saturable absorber, developed mainly for 1.3 ?m lasers Q-switching, was used as a passive Q-switch for the 1.03 ?m Yb-doped YAG (10% Yb/Y, 3mm long) and LuAG (15% Yb/Lu, 1mm long) lasers. Longitudinally diode pumped gain medium together with the V:YAG crystal were placed inside the 22mm long hemispherical laser cavity. For Yb-doped crystal excitation fibre-coupled (fibre core diameter 100 ?m) laser diode (max power amplitude 20W, emission wavelength 968 nm) was used. The laser diode was operatingin a pulsed regime (repetition rate 10 Hz, pumping pulse width 2 ms) to reduce parasitic thermal effects inside the gain medium. Stable Q-switching was obtained for laser output coupler reflectivity 70% and V:YAG initial transmission 70% at Yb laser emission wavelength. For the both tested active media the parameters of the generated giant pulses were similar. Pulses with duration of 2.5 ns (FWHM), energy about 0.3 mJ, and peak power up to 120kW were generated. The maximal Q-switched pul
