The characteristics of XeF and XeCl lasers stabilized by an external low-power ionizer were considered. Two laser operating regimes were investigated, one with a buildup of negative ions and the other with a discharge stabilized by an external low-po

A model is proposed for the reflection of coherent light by a rough surface and it includes a correction needed to allow for the polarization on reflection. This model is employed to investigate the spatial characteristics of radiation in the diffrac

The interaction of light waves in crystals with a quadratic nonlinearity is considered. It is shown that when one of the interacting waves carries information on the image of an object, such information can be transferred to a different wavelength, p

An analysis is made of a method for reconstruction of an image undistorted by the atmosphere from speckle interferograms (Knox–Thompson method). The quantum effects and the recording noise are allowed for in a modification of the Knox–Thompson me
