An Ar-ion laser with a measured single-mode linewidth of 5 MHz at 488 nm has been stabilized to approximately 1 MHz. The stabilization has been obtained by means of a Fabry-Perot interferometer as wavelength reference and a solid étalon as mode selector. The error signal is generated by modulation of the length of the laser cavity. The stabilization system is able to keep the wavelength fixed for periods of more than 100 h.
一台在488纳米处测得单模线宽为5兆赫的氩离子激光器已被稳定到约1兆赫。这种稳定是通过使用法布里-珀罗干涉仪作为波长参考和一个固体标准具作为模式选择器来实现的。误差信号是通过调制激光腔的长度产生的。该稳定系统能够使波长在超过100小时的时间段内保持固定。
