Resonant cavity electromagnetic theory

Brief Electromagnetic Theory of Microwave Resonant Cavities... 

In short note [23], Askar yan has pointed out two possible effects of oscillating surfaces on the electromagnetic field inside the (laser) resonator cavities. The first effect is the influence of oscillations on the generation and intensity of the laser radiation. It was extensively studied in many experiments, devoted, in particular, to such problems as the generation of optical pulses [24,25], phase locking of laser modes (where the frequencies of the mirror oscillations varied from 50 Hz [26] to 500 kHz [27,28] and 1 MHz [29,30] (see the review in Ref. 31), or modulation of the laser radiation [32,33] (in Ref. 33 the frequencies varied from 17 to 70 kHz). The theory of these phenomena was considered, for example in Refs. 34—36.
