| 摘 要： | 基于微片Ｎｄ∶ＹＡＧ 正交偏振双频激光器，研究了若干重要的双频激光器腔调谐现象， 包括光强调谐、频差调谐、子谐振腔效应及频差闭锁等，给出了实验结果和数据。腔调谐下，正交双频的频差调谐量约为３５０ ｋＨｚ；存在子谐振腔效应时，频差调谐量最大可达到２ ＭＨｚ；未发现明显频差闭锁现象，频差最小值可达到１４ ＭＨｚ。

| Abstract: | Studies on cavity tuning characteristics of dual-frequency lasers can be helpful for expanding laser physics theory and sensing applications. Based on microchip Nd:YAG orthogonally polarized dual-frequency laser, several important cavity tuning characteristics of dual-frequency laser are studied, including intensity tuning, frequency difference tuning, sub resonant cavity effect and frequency difference lock-in. Experimental results and data are presented. With cavity tuning, the variation of frequency difference between two orthogonally polarized frequencies can be up to 350 kHz; when sub resonant cavities exist, the maximum variation can be up to 2 MHz; frequency difference lock-in has not been found and the minimum frequency difference is about 14 MHz. |
