Abstract

Experimental data of the laser-induced damage thresholds of about 50 samples of NaCl crystals of different optical properties were analyzed. Simultaneous consideration of the damage data, obtained by nanosecond region lasers with wavelengths 10.6; 2.94; 2.76; 1.06; 0.26 micrometers permit to find, the threshold magnitude is a function of a dimensionless product of laser radiation frequency and a parameter of the sample having the dimension of time. The recommended empirical equation enables to explain many experimental data obtained earlier, to predict the laser induced damage threshold magnitude in the wide frequency range, and also the variation of this threshold as a function of temperature.
