Abstract:
An experimental investigation was made of the influence of vibration of one of the resonator mirrors on the competition between opposite waves in a ring single-isotope He–Ne laser emitting at a wavelength of λ = 0.63 μm, when the mirror vibration frequency was considerably less than the strength of the limit cycle. It was found that in the region of a strong interaction between opposite waves the use of a mirror vibrating in a wide range of frequencies with amplitude modulation of the resonator perimeter exceeding ~ 0.12λ made it possible to achieve stable two-wave lasing with practically identical amplitudes of the opposite waves.
