Paper Abstract

In this paper, it is described that two common methods to determine the thermal lens focal length (both assistant lens and double beams) with the analysis of their theoretical error, and proposed a new method to measure thermal lens focal length (M2) based on the relative beam propagation of Gaussian single and multi modes beam. The calculated equations of thermal lens focal length using proposed M2 method were reckoned, and its effectiveness has been testified by both the theoretical analysis and the experimental research.
