Electronic frequency tuning of an optically pumped far infrared waveguide laser has been achieved by using the Stark effect. Frequency modulation with a 50-kHz modulation frequency and an index greater than 1 has been observed as well as a maximum modulation frequency of 300 kHz.
利用斯塔克效应实现了光泵浦远红外波导激光器的电子频率调谐。已观察到调制频率为50千赫且调制指数大于1的频率调制，以及高达300千赫的最大调制频率。
