HM: Nd:Yag Dual Wavelength Mirror
HM: Nd:Yag Dual Wavelength Mirror
High power, high reflectivity dualband Nd:YAG laser line mirrors for 0°-and-45° AOI ; 532 & 1064 nm. High reflectivity is achieved at two Nd:YAG laser wavelengths in this high laser damage threshold, durable e-beam dielectric coated mirror. Available for use at 0° or 45°, they offer > 99.0% reflectivity at the Nd:YAG fundamental wavelength and its second harmonic. Custom mirrors are available upon request.
