Tunable Fe:Cr:ZnMgSe Gain-switched Mid-IR Laser Operating at Room Temperature

Popis výsledku v původním jazyce

The goal of this work was to design and investigate the gain switched new Fe,Cr:ZnMgSe laser operating at the room temperature. The pumping was provided by the electro-optically Q-switched Er:YAG laser with the oscillation wavelength of 2.937 ?m which matching the absorption line of the Fe,Cr:ZnMgSe crystal. The Q-switched operation was obtained by the Brewster angle cut LiNbO3 Pockels cell placed between the rear mirror and the laser active medium. The output radiation parameters were: the energy of 10mJ, pulse duration of 120 ns, and repetition rate 1 Hz. The pump radiation was directed into the Fe,Cr:ZnMgSe crystal placed inside the 16 mm long hemi-spherical cavity formed by the dichroic pumping mirror (T = 86 % at 2.94 ?m and R = 100% for 4 - 5 ?m) and the output coupler with the reflectance R = 95 % at 4 - 5 ?m and radius of curvature r = 500 mm. The maximum output Fe,Cr:ZnMgSe laser energy was 160 ?J corresponding the slope efficiency 4 % (with respect to absorbed energy). The g
