Thermal Camera for enhanced Laser Damage Testing (UNC at Charlotte)
Abstract
High power laser systems can suffer damage from uncoated optics and traditional anti-reflection (AR) thin-film coated optics, having low laser damage threshold (LIDT). Sub-wavelength random anti-reflective surface structures (rARSS) have been shown to have a higher laserinduced damage threshold than traditional AR coatings. Continuous-wave (CW) LIDT testing is predominantly a thermal effect, and evaluation of various optical materials and anti-reflection treatments could be enhanced by integration of a high resolution thermal camera.
