Paper Abstract

The laser damage thresholds and other properties of 352 nm fluoride AR coatings for KDP substrate were investigated. The HoF3 (or LaF3)/AlF3 AR coating deposited by IAD process had a high threshold of 24 J/cm2 (10 ns) when the laser conditioning procedure was used. These fluoride ARs were durable for wiping and also did not degrade during more than one year under room atmosphere.
