Paper Abstract

The Laser-induced damage behavior of narrow-band interference filters was investigated with a Nd:YAG laser at 1064nm under single-pulse mode and free-running mode. The absorption measurement of such coatings had been performed by Surface Thermal Lensing (STL) technique. And the relationship between damage morphology and absorption under the two different laser modes had also been studied in detail. The explanation is given by the standing-wave distribution theory.
