Laser-Induced Damage of Ta2O5/SiO2 Two-Cavity Narrow-Band Interference Filters
The laser-induce damage threshold (LIDT) of Ta2O5/SiO2 two-cavity narrow-band interference filters with different central wavelength was investigated with a Nd∶YAG laser at 1064 nm under single-pulse mode, and the absorption measurement of such coatings was also performed by surface thermal lensing (STL) technique. It is found that the narrow-band interference filters showed different laser-induced damage behavior in the different zone (interband, band edge and rejection zone) of such coatings under high power laser irradiation. Using the electric distribution theoretical calculating, the experimental results have been analyzed in detail. The laser-induced damage behavior of such filters are in agreement with theoretical prediction.
