Abstract
Precision Photonics Corporation (PPC) has developed high Laser Damage Threshold (LDT) coatings for the important 2-3μm spectral region. Accurate information for both LDT and absorption for such coatings is sparse and often unreliable, especially when compared to the huge amount of information for these parameters in the 1μm spectral region. The goal of this effort is to provide useful, accurate information for high power/energy coatings, given the limited LDT and absorption testing capabilities for the 2-3μm region. In this paper, we present data for 2μm pulsed LDT, 2μm absorption, 3μm pulsed LDT, and Continuous Wave (CW) LDT data.
