We report here the possibility of controlling the position of the standing-wave pattern in a ring-laser cavity at rest thanks to diffraction. Modulating the position of the aperture along the beam axis induces a beat frequency between the two counter

Diffraction losses and resonant frequencies of a gas laser resonator perturbed by an off-resonance dispersion profile, due to nonuniform radial distribution of excited atoms, are predicted by extending the ray transfer matrix formalism. These predict

Diffraction is shown to play a dramatic role in the frequency characteristics of ring-laser gyroscopes. It is proved theoretically and experimentally that a small misalignment of the cavity leads to a nonreciprocity of the resonant diffraction mechan

In the framework of the {ital ABCD} ray matrix formalism, a theoretical model is proposed to describe the fundamental TEM{sub 00} elliptical Gaussian-mode size variations due to frequency-dependent lenslike effects in ring lasers. Two different mode

The asymmetry observed in intracavity resonances (especially of the Lamb-dip type) is attributed to a resonant nonlinear diffraction effect. Direct evidence of this effect is obtained by a new experiment and careful analysis of the diffracted light,

It is shown that three different critical geometries can exist for a half-symmetric resonator with an internal lens of variable focal length. Indeed, in addition to the previously demonstrated critical geometry leading to a mode size on the spherical

In a laser resonator, a part of the diffracted light is picked-off with a knife-edge mirror. It is shown experimentally that the ratio of this picked-off light to the laser output exhibits a linear dependence on the diffraction losses which are varie

An asymmetric stable laser resonator with one large mirror and the other mirror apertured is considered. An equivalent symmetric resonator is derived which enables the determination of the theoretical diffraction losses from Li's computations. Experi
