“…Optics damage due to these very high peak power lasers is always of concern [24]. Studies [25][26][27][28] for developing scaling laws relating laser fluence, pulse width, and pulse shape to damage probability exist but are difficult to test since most lasers do not have welldefined temporal and spatial pulse shapes. A HHP-HAP laser that has a FIT (flat in time) pulse shape with user-selectable pulse width as well as a spatially flat beam profile can be an excellent tool to raster scan optics and acquire large amounts of statistical data to test the scaling laws.…”

An automated test station to measure the laser-induced damage threshold (LIDT) according to ISO 21254-1,2,3,4:2011 standards is presented. The laser is a single longitudinal mode, 500 mJ, 6 ns, Q-switched, 10 Hz, linearly polarized, 1064 nm laser, with 2-nd and 3-rd harmonic capabilities. The machine is able to operate the S-on-1 test (S = 500), or the Type 2 endurance (durability) test. The main blocks of the station are described, emphasizing some original solutions. Preliminary results of LIDT measurements using the S-on-1 test on several coatings and on uncoated fused silica substrates with various degrees of roughness are also presented.
