The 20QM20HM.45 High-Energy Nd:YAG Laser Mirror is manufactured using high purity fused silica substrates and ultra hard dielectric coatings. This 50.8 mm diameter mirror has been tested and certified to withstand high-energy pulses and has a high damage threshold. Meticulous production procedures guarantee they will withstand fluences greater than 10 J/cm2 at 1064 nm. The coating is highly durable and will withstand repeated cleaning. This frequency-tripled 354.7 nm Nd:YAG mirror has a 45° incidence angle. Reflectivity is greater than 99.7% for s-polarization and greater than 99% for p-polarization.
