Title

Influence of radiation polarization on optical breakdown threshold of glasses by two beams

Abstract

To investigate the intrinsic laser induced damage of transparent dielectrics the tight focusing of radiation inside samples bulk is usually used. In this case the threshold electric field strength of light radiation is calculated starting from irradiance, and the customary formulae for non focused radiation are used. At the same time under tight focusing conditions the vectors of electrical field strength of diametrically placed rays are directed under large angles each to another. In this work it is experimentally shown that the calculations performed on the basis of customary formulae can lead to the substantial errors in quantitative estimation of field strength.
