摘要
The laser-induced damage behavior of narrow-band interference filters was investigated with a Nd:YAG laser at 1064 nm under single-pulse mode and free-running laser mode. The absorption measurement of such coatings has been performed by surface thermal lensing (STL) technique. The relationship between damage morphology and absorption under the two different laser modes was studied. The explanation was given by the standing-wave distribution theory.
