Nd:YAG Laser Line (HR) Mirrors are designed for fundamental (1064 nm) or harmonic (532, 355, 266 nm) Nd:YAG laser beam steering. Custom material, size, shape and other parameters available. What is Nd:YAG Laser Line (HR) Mirror? Nd:YAG Laser Line (HR) Mirror is an optical component coated with dielectric thin-film coating stack. This mirror is specifically designed to reflect Nd:YAG laser harmonics. Unlike output couplers (partial reflectors), these mirrors are designed and manufactured in such way to achieve maximal possible reflection value, instead of specific reflection value. How Nd:YAG Laser Line (HR) Mirrors are produced? Similarly to Yb:YAG and Ti:Sapphire Laser Line MIrrors, Alien Photonics Nd:YAG Laser Line (HR) Mirrors' production begins with optical substrate preparation – polishing and inspecting them. The next step is coating design – these mirrors are optimized for specific Nd:YAG laser line (single band, narrow band) and the design goal is to either make the best possible reflection (HR) or produce mirrors with high laser induced damage threshold (LIDT). Based on the priority, specific coating materials are chosen. Coating also can be optimized for specific angle of incidence (AOI). Most popular AOI’s are 0°, 45° or 56°. Alien Photonics also offers custom angle of incidence optimizations: 5°, 8°, 12, 22.5°, etc. If you'd like your mirror to work at several incidence angles? No problem, just let us know the range. How to handle and clean Nd:YAG Laser Line (HR) Mirrors? Dielectric coated Nd:YAG Laser Line (HR) Mirrors are way more resistant to physical contact and environmental impact when comparing to bare metal coated mirrors (Au, Ag, Al).
