Abstract: (146 Views)
In this paper, the thick thermal lens approximation is evaluated for a CTH:YAG laser with a standard telescopic resonator. An accurate relation between the thermal lensing parameter and lens-like media factor is proposed. Telescope adjustments were studied based on the practical values of the focal length of the thermal lens. The fundamental mode volume is determined regarding the Hermit-Gaussian theory, and the influence of the defocus parameter is examined. The study emphasizes the importance of considering both the fundamental mode volume and the distance to the stability boundary when selecting the optimal defocusing parameter. A merit factor was introduced that provides a comprehensive approach to selecting the most suitable defocus parameter for the system.
