The LBTEK high-power 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. The LBTEK high-power laser line mirrors are highly efficient reflectors optimized for single-wavelength ranges. The UV fused silica substrate of LBTEK high-power laser line mirrors offers better uniformity and lower thermal expansion coefficients, ensuring superior performance under temperature fluctuations and enhanced resistance to environmental impacts. The LBTEK high-power laser line mirrors are available in seven working wavelengths: 266 nm, 355 nm, 532 nm, 780 nm, 1064 nm, 1550 nm, and a dual-wavelength option of 532 & 1064 nm, with an incident angle range of 0-45° and reflectivity exceeding 99%.
