Our high-energy Nd:YAG laser mirrors are manufactured using high purity fused silica substrates and ultrahard dielectric coatings. These mirrors have been specifically designed to withstand high-energy pulses and have a high damage threshold. Meticulous production procedures guarantee they will withstand fluences greater than 10 J/cm² at 1064 nm. The coatings are highly durable and will withstand repeated cleaning. Our new HE.1 and HE.2 coating can withstand as high as 40 J/cm² at 1064 nm and 8J/cm² at 532nm energy fluences respectively.

We offer Nd:YAG mirrors for the fundamental 1064, frequency-doubled 532, frequency-tripled 354.7, and frequency-quadrupled 266 nm laser lines at either 0° or 45° incidence angle. A dual-wavelength mirror for 1064 and 532 nm is also available. Reflectivity is greater than 99.7% for s-polarization and greater than 99% for p-polarization. These mirrors are available in 25.4 or 50.8 mm diameters.
