摘要： A method is described for quantitative determination of suitability of an optical material, especially alkali halide and alkaline earth halide single crystals, for optical components exposed to high energy densities, especially of pulsed laser light at wavelengths under 250 nm. In this procedure radiation-dependent transmission of the optical material is determined at ultraviolet wavelengths by fluorescence measurements for fluorescence induced by ultraviolet radiation at these ultraviolet wavelengths. This is accomplished by a method including determining an induced fluorescence maximum of a non-linear absorption process, measuring a slope (|dT/dH|) of a functional relationship representing the dependence of the radiation-dependent transmission on fluence (H) for the induced fluorescence and determining radiation-dependent transmissions from this slope for particular fluence values.

摘要： The method tests the suitability of an optical material having a radiation-induced absorption, especially of an alkali or alkaline earth halide, for production of an optical element exposed to high-energy irradiation. The method includes pre-irradiating the optical material with laser radiation until rapid damage induced in the optical material with the laser radiation is saturated; subsequently measuring fluorescence of the optical material during and/or immediately after irradiating the optical material with excitation radiation and determining the non-intrinsic fluorescence and intrinsic fluorescence present in the measured fluorescence. Suitability may be preferably determined according to a ratio of the amount of non-intrinsic fluorescence to intrinsic fluorescence. A device for performing the method including a barrier device for blocking scattered excitation radiation is also provided.

摘要： The present invention refers to a method for the quantitative measurement of the pulse laser stability of synthetic silica glass, whereby this method avoids time-consuming and demanding measurements and saves material. First, the absorption of silica glass is measured for different energy densities, and a non-linear function α1 (H) is determined on the basis of the measured values. Second, the silica glass is subject to radiation with a higher energy density up to the point at which a constant absorption value is achieved. In the following, the absorption of the silica glass is measured at different energy densities, and a non-linear function α2 (H) is determined. The difference between the two non-linear functions indicates the increase of absorption that depends on the energy density.
