Antireflection coatings on LBO crystals: investigation of LIDT scaling with pulse duration at IR and UV wavelengths.
On demand starting 12 October 2021
The laser-induced damage threshold (LIDT) of anti-reflective (AR) coatings is a limitation when it comes to the maximum laser power. Furthermore, LIDT data for AR coatings on nonlinear crystals are rather scarce in scientific literature, mainly available for ns pulse durations. Lately, however, ps and fs pulse durations are also becoming important. Thus, in this work, four LBO crystals were IBS coated on both sides with two distinct coatings, namely, AR@1064 nm and AR@355 nm. These coatings were then LIDT tested for both UV and IR wavelengths with ns, ps, and fs pulses.
