Damage Measurements on Optical Materials for Use in High-Peak-Power Lasers


Recently, we have expanded our efforts to develop state-of-the-art optical components for use in large-scale, high-peak-power, solid state lasers. Laser-induced damage to many of these components sets critical constraints on construction costs and limits the peak powers attainable in current and proposed devices. Increasing the damage threshold whenever possible by improving materials fabrication technology is therefore the ultimate goal of our work. The optical components and technological developments we are investigating are: Highly reflective mirrors • Kilo-layer coatings fabricated by high-temperature, plasma chemical vapor deposition (PCVD) • Laser conditioned physical-vapor-deposition (PVD) coatings • Multi-layer sol-gel coatings Anti-reflective coatings • Single layer sol-gel coatings deposited on substrates and non-linear crystals Non-linear crystals • High purity KDP, LAP and related frequency conversion crystals Substrates and laser hosts • High threshold surface preparation techniques • High threshold bulk materials Polarizers • Advanced PVD multi-layer coatings

Our research has resulted in an extensive database of laser-damage measurements. We present summaries of these measurements with particular emphasis on those taken at 1064 nm and 355 nm.
