Abstract
We have developed an experimental method for estimating the thermal lens effect of a Nd:YAG rod during laser oscillation in a high-power pulsed laser. By combining a stability analysis by cavity simulation with the change in the focal length of the rod and the beam quality according to the input, we were able to correct the reduction of the thermal effect on the rod due to laser oscillation. The proposed method makes it possible to design a resonator that appropriately considers the stability of the resonator that changes in accordance with the input power.
期刊介绍：
The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
