摘要
在分析了半导体激光泵浦与氪灯泵浦激光器各自特点的基础上, 提出了在氪灯泵浦腔内倍频 Nd:YAG激光器上进行不稳定性和混沌研究以及探索混沌消除方法的设想。给出了理论分析和实验装置, 实验测量得到了混沌激光辐射和功率谱, 数值分析给出相应的时间行为和相空间吸引子。当在腔内引入 Nd:YAG色心调制晶体后, 实验上得到了稳定的周期输出, 从而实现了混沌的消除。
Abstract
In this paper, base on analysing the characters between the diode-pumped and krypton flashlamp-pumped lasers, we put forword a study of instability and chaos and of the elimination of chaos in krypton flashlamp-pumped intracavity frequency-doubled Nd:YAG lasers. Theoretical analyses and experimental apparatus are given, the results of chaotic laser radiation and its power spectra obtained through numerical calculation and experimental measurement are presented. By putting a Nd:YAG color center crystal in the resonator, the stable periodic laser radiation is attained and the elimination of chaos is realized.
