Laser damage lifetime tests under the presence of outgassing contaminants

We investigated the formation of IR and UV lased induced deposits on BK7 and fused silica optics under simulated space conditions in presence of outgassing materials. We used a Nd:YAG laser with 1064 nm and 355 nm wavelength, 3 ns pulse length and 100 Hz repetition rate. Optics were exposed to fluence values in the range of 0.1 - 1.0 J/cm 2. As contaminants epoxy, silicone and polyurethane containing materials were used
