An investigation was made of the amplitude characteristics of a double-mode He—Ne/CH4 laser with linearly and orthogonally polarised modes, when the cavity was frequency-modulated at a frequency close to the intermode spacing. Under these condition

Theoretical and experimental investigations were made of the reaction of the laser power to an external radiation signal. The laser with an injected signal (LIS) was an He—Ne laser emitting radiation at the wavelength of 3.39 μm in the form of two

An investigation was made of the natural intensity fluctuations in single- and double-mode CO2 lasers. The profile and level of the natural intensity fluctuations were determined. It was shown that the main mechanism for the formation of natural inte

An investigation was made of nonlinear resonances in the spectral density of the natural frequency fluctuations of the intermode beats of a two-mode He–Ne laser (λ = 3.39 μm) with an internal methane absorption cell. The amplitude and width of th

A study was made of the feasibility of using two-mode gas lasers in remote detection of small vibrations of objects. Vibrations of ~ 10−3λ amplitude (where λ is the radiation wavelength) were detected at a distance of 3–5 m in a frequency range

Equations describing changes in the slowly varying amplitudes and phases of the field, taking into account the slow response (inertia) of the active medium, are derived for a two-mode gas laser. It is found that allowance for the inertia does not inf

An investigation was made of the interaction of the modes with orthogonal and parallel polarizations in a gas laser emitting two axial modes. The behavior of the critical frequency and stability region of the two-mode emission was determined as a fun
