Abstract

Under the condition of high power diode side pumping, thermal effect in working medium is a serious problem. Not only total pump power, but also special pump structure, such as pump geometry structure, divergence of diode laser, distance from diode to working medium will affect the result of thermal effect. In this paper, by means of computer program, we found a series of thermal effect model, by simulating the temperature transformation process and stable-state temperature distribution. Based on this, we get the theoretical results of thermal lens focus length and thermal induced bi-refraction, and compare it with the experiment results.
