Gain Switched Fe:ZnMgSe Laser Oscillation under Cryogenic Temperature

Popis výsledku v původním jazyce

The spectroscopic and laser properties of bulk Bridgman-grown Fe,Cr:Zn1-xMgxSe single crystals with the various concentrations of Mg (x = 0.19; x = 0.27; x = 0.38) were investigated in a wide temperature range. Pumping was provided by a 2.94 um Q-switched Er:YAG laser with a maximal energy of 15 mJ in 120 ns pulse and repetition rate 1 Hz. Q-switched operation was achieved by the Brewster angle cut LiNbO3 Pockels cell placed between the rear mirror and the Er:YAG laser active medium. Pump radiation wasdirected into the Fe:ZnMgSe crystal placed inside the LN cooled dewar. The 55 mm long plane-concave cavity was formed by a dichroic pumping mirror (T = 92 % @ 2.94 um and R = 100 % @ 4 - 5 um) and an output coupler (R = 95 % @ 4.5 um, r = 200 mm). A strong dependence of output pulse energy on temperature was observed for all samples. The maximum output Fe,Cr:Zn1- xMgxSe laser energy was 230 uJ and 180 uJ (for Mg concentration x = 0.19 and x = 0.38, respectively) for gain switched operati
