摘要

本文详细分析了端泵浦Nd:\(\hbox {YVO}_4\)激光器的横向模式退化过程。通过观察凹面-平面腔中拍频信号的交点，可以清楚地确定横向模式退化的确切腔长位置，这也是横向模式锁定发生的位置。对 1/3 和 2/7 退化位置的研究表明，横向模式锁定发生在微米范围内。我们的研究结果简单直观地描述了普通固体激光器的频率退化现象

Analysis of beat frequencies of transverse mode degeneracy in diode-pumped Nd:YVO4 laser

This paper provides a detailed analysis of transverse mode degeneracy process of end-pumped Nd:\(\hbox {YVO}_4\) laser. By observing the intersection of the beat frequency signals in the concave-plano cavity, the exact cavity length position of the transverse mode degeneracy can be clearly identified, which is also where transverse-mode locking occurs. Investigating the positions of the degeneracy of 1/3 and 2/7 reveals that transverse-mode locking occurs within the micrometer range. Our results give a simple and intuitive description of frequency degeneracy in a common solid-state laser
