Characteristics of Transversely Diode-Pumped Nd:YAG Laser with Cr:YAG Passive Q-Switch within Wide Temperature Range

https://doi.org/10.47612/0514-7506-2023-90-2-143-148

Abstract

The dependence of the initial transmission S0 of passive Q-switch based on Cr4+:YAG crystal on temperature T has been experimentally investigated. It has been shown that the initial transmission is increased from 16.3 to 24.0 % with temperature changes from –40 to +60°С. The resulting curve S0(Т) is approximated by a straight line with a slope ratio of 0.076 %/degree. At a constant pumping level, the energy of the generated pulses E of the Nd:YAG laser decreases from 100 to 90 mJ, and the pulse duration t increases from 9.3 to 12.0 ns with an increase in the T value in a given interval. The numerical calculations of the E(T) and τ(T) curves agree with the experimental data. The results obtained make it possible to more accurately predict the results of the temperature tests of compact diode-pumped neodymium lasers.
