0.532 \mum laser conditioning of HfO2/SiO2 third harmonic separator fabricated b

The 0.532-\mum laser conditioning of HfO2/SiO2 third harmonic separator fabricated by electron-beam evaporation (EBE) was studied. The laser induced damage threshold (LIDT) of the separator determined by 1-on-1 test is 9.1 J/cm2 and it is 15.2 J/cm2 after laser conditioning determined by raster scan
