Thin-wire bolometer for measuring the intensive laser radiation parameters

Abstract

The aim of this article is the substantiation of a measuring method of spatially-energy and polarization parameters of an intensive and wide-aperture laser radiation by a profile three-lattice thin-wire bolometer. The thin-wire bolometer withstands high densities of optical radiation, works in a broad spectral gamut, is rather low-inertia and is a polarization device. The three-lattice profile thin-wire bolometer allows one to measure the following parameters of laser radiation: continuous power, energy of a single impulse, the direction of linear polarization or parameters of an elliptical polarization, integrated coefficient of the nonuniformity of an intensity distribution, root-mean square radius of a beam, generalized beam area, and polarization coefficients of the interaction with bolometers.
