Comparative studies of laser-induced damage of several single-layer optical films

The effect of porosity on the laser induced damage threshold of TiO2 and ZrO2 single layer films

“…Therefore, one of the main bottlenecks for scaling up high power laser systems is the enhancement of the laser damage resistance of the optical elements. The energy density at which laser induced damage occurs is defined as the laser induced damage threshold (LIDT) [1]. LIDT is affected by different parameters of the irradiation light, such as the laser pulse duration [2], repetition rate [3] and radius of the beam [4].…”
