摘要
用端面研磨法来弥补激光棒热透镜效应是一种传统的方法。在推导更为精确的激光棒端面研磨半径公式时,发现了激光棒的自消热透镜效应现象。把激光棒等效为梯度折射率棒,得到了新的热透镜焦距公式。从新的焦距公式出发,理论证明了激光棒自消热透镜效应现象,并详细分析了该效应产生的原因。
Abstract
Extremity ground (end cap) method is better means to compensate thermal lens effect in laser rod. The self-compensated thermal lens (SCTL) effect phenomenon was found from the deduced equation of radius ground. Based on that the laser rod is equivalent to gradient index rod (GRIN), a new thermal lens focal length expression was achieved. From it the effect of self-compensated thermal lens was found, and analyzed.
