Paper Abstract

A setup was developed at Laser-Laboratorium that allows determination of LIDT data under simultaneous 1064nm, 532nm and 355nm irradiation (3l), in order to investigate the influence of combined irradiation of specific elements with multiple wavelengths. Utilizing a fully characterized test laser beam and a well defined sample environment, 10.000-on- 1 LIDT data of high-reflecting mirrors (AOI 45°) in vacuum were determined both at multiple wavelengths (3l) and at 355nm alone. In addition, a test optics (HR355, 45°, ambient conditions) was irradiated for 150 million pulses at (3l) at a fixed fluence of 2 J/cm2 as a certification test.
