Evaluation of bichromatic coatings designed for pulsed laser fusion applications at 0. 53 and 1. 06 micrometers
Various bichromatic coatings designed to operate at both 0.53 and 1.06 micrometers have been evaluated for spectral performance and laser damage threshold to determine the suitability of these coatings for 1 nanosecond pulse laser fusion experiments and to establish baseline data. Anti-reflection, partially transmitting high reflection, and maximum reflection coatings, consisting of titania and silica layers, were deposited onto BK-7 substrates. For each type of coating, two different designs were examined. Spectral measurements indicate the coatings met performance goals. Laser damage threshold values at 1.06 micrometers were similar to those of previous monochromatic production coatings, while damage levels at 0.53 micrometers were about one-half these 1.06 micrometer values.
