Referring to LIDT measurements at fs and ns regime, we’ve observed our s-waveplate has laser irradiation resistance similar to uncoated fused silica substrates.

LIDT value measured at 1064 nm, ~10ns is 63,4 J/cm2 and it is not dropping while increasing exposure time. It proves, our waveplates are very high performance, suitable for high power laser applications.
