| Abstract: | Based on the Hartman-Shack sensor, laser beam analyzer and resonator theory, a real-time measuring method for thermal lens focus of solid-state lasers was devised in the case of operating. This method is simple, convenient and practical. Thermal lens focus of rod laser end-pumped by continuous laser-diode was measured using this method. The experimental results were compared with the theoretical data, and the result and was analyzed and discussed. It provides theoretical reference for the design of solid-state lasers and experimental study. |
