Abstract: (1848 Views)
In this paper, increasing the laser induced damage threshold of Nd:glass by 10.6 µm CO2 laser is investigated. For this purpose, Nd:glass samples were irradiated with different laser parameters. Then, transmission and differential absorption spectra of samples before and after the irradiation were compared. Next, a 1064 nm Q-switched oscillator-amplifier Nd:YAG laser system with single longitudinal mode TEM00 pulses was used for the damage threshold experiment. By optimizing CO2 laser irradiation parameters, damage threshold for an irradiated sample was increased about 3.10 times. The results of this study are very important, considering that Nd: glass is used as an active medium and amplifier in high-power lasers.
