本文提出了一种确定激光二极管泵浦固体激光器增益介质中热透镜焦距和泵浦光束腰的方法。该方法利用谐振腔变换圆理论，既简单又可靠。利用测量的热透镜焦距计算了泵浦激光在增益介质中的束腰。测量和分析了热透镜对输出功率的影响。
A method to determine the focal length of a thermal lens and pumping laser beam waist in the gain medium in laser-diode-pumped solid-state lasers is presented. This method, using resonator transform circle theory, is both simple and reliable. The measured focal length of the thermal lens is used to calculate the beam waist of pumping laser inside the gain medium. The effect of the thermal lens on the output power is also measured and analyzed.
