The LBTEK Nd:YAG laser line mirrors are manufactured using high-purity UV fused silica and ultra-high laser-induced damage threshold (LIDT) dielectric coatings, capable of withstanding high-energy pulses with superior damage thresholds. Designed for the fundamental, second, third, and fourth harmonics of Nd:YAG lasers, LBTEK's Nd:YAG laser line mirrors feature UV fused silica substrates that offer better uniformity and lower thermal expansion coefficients. This ensures superior performance under temperature fluctuations and enhanced resistance to environmental influences. The LBTEK high-power laser line mirrors operate at wavelengths of 262 nm-268 nm, 349 nm-358 nm, 523 nm-537 nm, and 1046 nm-1074 nm, with an incident angle range of 0° to 45°. They achieve reflectivity exceeding 99% for both S- and P-polarized light.
