激光稳频技术激光单元技术之一。激光器的输出波长或频率在某些应用场合下是不希望发生无规变化的；特别是用作高精度光谱测量或有关计量标准时，不但要求输出激光有尽可能高的单色性（为此可采用选纵模技术），而且还进一步要求振荡激光的精确频率位置不发生随机式的漂移变化。为此就必须采用专门的激光稳频技术。一般而言，激光振荡频率的漂移式变化，是由于共振腔的等价腔长（光程长度）的漂移变化所引起的。因此，为稳定激光的振荡频率，首先应保证几何腔长和腔内各固定元件的机械稳定性，并同时保证器件运转环境和有关物理参量(特别是温度和腔内通光媒质的折射率)的稳定。即使在做到上述各点之后，由于激光振荡过程多种因素的影响，仍然有可能使振荡频率发生微小程度的漂移和变化，为此，可进一步采取更有效的频率自动稳定控制系统。此系统通常由以下三部分组成。① 误差信号监测装置。该装置的作用是监测输出激光频率变动并给出与偏移量成正比的光电误差信号；法布里－珀罗干涉仪、频谱分析仪、具有固定窄吸收峰的饱和吸收媒质以及具有稳频本机振荡器的光学外差接收器等装置，均可起到上述监测作用。② 误差信号反馈放大装置。通常为一组电子线路，其功能是将误差信号以电信号形式加以检测放大，然后反馈输入到自动校正装置。③ 频率自动校正装置。激光振荡频率的严格数值是由共振腔光学长度所决定的，因此当实际振荡频率偏离预定的数值时，由反馈系统输入的误差信号可通过压电作用调整共振腔反射镜的前后位置以改变几何腔长，或者通过线性电光效应改变置于腔内的电光晶体的折射率（相当于改变腔的光程长度），使激光振荡频率向相反的方向发生变动，以抵消已产生的偏差影响，从而可保持实际激光振荡频率的自动稳定控制。目前采用以饱和吸收媒质为监测手段的气体激光器稳频系统，频谱精度δv/v（这里v为激光频率, δv为频率漂移量）可达10-11～10-13量级左右。
