Mathematical Models and Computer Simulations > 2019 > 11 > 2 > 277-286

The paper proposes a mathematical model of a multistage laser based on three- and four-level active media in the plane-wave approximation. The model can be used to analyze the generation of radiation in a laser source in the presence of interstage couplings taking into account the actual quality of the optical path elements. The calculation of the pulse parameters for YAG:Nd and YSGG:Cr:Nd laser oscillators...

The possibility of generating and detecting high-frequency gravitational waves based on nonlinear-optical processes in dielectric media at their excitation by intense laser radiation of visible or ultraviolet ranges is analyzed. The theory predicts the feasibility of the Hertz gravitational laboratory experiment in which the parametric conversion of intense laser radiation with frequency ω₀ = 2πf₀...

Optics and Spectroscopy > 2016 > 121 > 6 > 901-906

The physical mechanism of alteration of intensity of linearly polarized monochromatic electromagnetic radiation with λ = 630 nm in a revolving dielectric disk with a mirror coating is examined. The effect is induced by elastic deformation due to the revolution and by thermoelastic deformation of the optically transparent disk. These deformations result in birefringence, the polarization plane rotation,...

A luminescent trace has been observed in a ruby crystal (Al₂O₃: Cr³⁺) that rotates at a frequency of 2 to 200 Hz and is irradiated by 532-nm coherent electromagnetic radiation. A method has been proposed to determine the lifetime of the excited electronic state of chromium ions from the measurement of the length of an arc of the trajectory of a light spot on the surface of a rotating ruby single crystal...

A relativistic expression has been obtained for the curvature of trajectory of the wave vector of an electromagnetic wave in a moving optically transparent medium. It has been shown that the curvature of the trajectory and angular deviation of rays appear in a homogeneous isotropic medium if the gradient of the velocity field in the medium is nonzero. The bending of the trajectory in the medium with...

A gravitational-wave antenna classification according to known methods of gravitational radiation detection is proposed for the first time. Underlying the classification is the principle of spatial formation of the measuring channel, i.e., on the Earth's surface, in near space, within the solar system, and on cosmological scales.
