Laser Damage Database at 1064 nm


In conjunction with our diversification of laser damage testing capabilities (see “Expanded Damage Test Facilities at LLNL” this conference), we have expanded upon a database of threshold measurements and parameter variations at 1064 nm. This includes all tests at low pulse-repetition frequencies (PRF) ranging from single shots to 120 Hz. These tests were conducted on the Reptile laser facility since 1987 and the Variable Pulse Laser (VPL) facility since 1988. Pulse durations ranged from 1 to 16 ns. The table below summarizes the test data scaled to 10-ns pulses.
