Abstract:
An experimental and theoretical investigation is reported of the effect of the modulation frequency of the resonator perimeter on the operation of an He–Ne/CH4, ring laser at λ = 3.39 μ. It is shown that at high modulation frequencies (F>5–7 kHz), the amplitude of the first intensity harmonic IΩ at the center of the methane "reflecting" power peak does not vanish in the general case and depends strongly on the pressure in the active medium. At a pressure corresponding to coincidence of the centers of the amplification and absorption lines, IΩ has a minimum at the peak extremum. This effect yields a simple and accurate method of matching the line centers of the active and absorbing media. A dependence of the stabilized laser frequency on the phase of the wave back reflections is also reported.
