提出了一种利用弛豫振荡频率测量单频激光器腔内损耗的简单方法。通过对单频激光器的弛豫振荡频率,输出功率以及腔内损耗之间关系的分析,理论得到了单频激光器腔内损耗的表达式;通过在实验上测量单频钛宝石激光器的输出功率和相应功率下的弛豫振荡频率,利用理论计算公式以及钛宝石激光器的相关参数即可获得激光器的腔内损耗值。
A simple method to measure the loss in the single-frequency laser cavity by using the relaxation oscillation frequency is proposed. Through the analysis of the relationship between the relaxation oscillation frequency, the output power and the cavity loss of the single-frequency laser, the expression of the loss in the single-frequency laser cavity is theoretically obtained. By experimentally measuring the output power of the single-frequency titanium sapphire laser and Corresponding to the power of the relaxation oscillation frequency, the use of theoretical formula and the relevant parameters of the titanium sapphire laser laser cavity gain value can be obtained.
