Influence of Temperature on Nd:YAG/V:YAG Compact Laser Generation at 1444 nm
Original language description
Compact Q-switched diode-pumped laser, emitting radiation at eye-safe wavelength 1444 nm, was studied. This laser was based on composite crystal consisting of 4 mm long Nd:YAG active medium diffusion bonded with 1 mm long V:YAG saturable absorber. The laser resonator mirrors were directly deposited onto the composite crystal surfaces. The output coupler with reflectivity 94 % for the generated wavelength 1444 nm was placed on the V3 + -doped part. Temperature dependence of giant pulse energy and lengthwas studied independently on pumping pulses duty cycle. It was found that for constant duty cycle 1 % and for crystal holder temperature rise from 8.2 up to 43.2 C the pulse width dropped from 31 to 5.1 ns and pulse energy rose from 17 to 57 uJ. From a mathematical model of passively Q-switched laser it follows that this behaviour can be explained by temperature caused increase of ground-state absorption and ground-state to excited-state absorption ratio of V:YAG saturable absorber.
