High Power Laser Mirrors are optical mirrors engineered to withstand high and intensive Laser-Induced Damage Threshold (LIDT), offering capabilities of handling laser beams of high energies without degradation. High power laser mirrors are essential for applications requiring precise beam control and minimal loss. 

Shanghai North Optics offers standard and custom high power mirrors. Our high power mirrors consist of dielectric coatings deposited on UV-fused silica mirror substrates. The dielectric coatings of North Optics’s high power laser mirrors feature a high laser induced damage threshold of >20J/cm2@1064nm, 10ns, 10Hz pulses, designed to endure high laser energies. The damage thresholds of the dielectric coatings are rigorously inspected. The high-power mirror also features excellent reflectivities at the critical wavelengths (at the designed AOIs and polarization).

The durable substrates of our high power mirrors are manufactured using UV Fused Silica (Corning 7980), this optical glass material, when selected as an high power mirror substrate, excels with low thermal expansion and superior damage threshold (You can click here to view a detailed introduction to optical substrate materials). This makes our high power mirror mechanically robust and thermally stable. 

Meticulously crafted with high precision and laser-grade surface quality/surface flatness, North Optics’s high power laser mirrors deliver surpassing high-power performance, great efficiencies for reflecting high energy laser beams, minimized scatter losses, low wavefront distortion, and cost-effectiveness. While primarily used for high-energy pulsed lasers (from nanosecond, picosecond, to femtosecond scales), our high power laser mirror can also be applied to continuous wave (CW) laser systems. Our high-energy mirrors' robust construction and specialized coatings ensure exceptional reflectance, making them ideal for demanding laser applications such as laser processing, medical lasers, and scientific research.

Our high power laser mirrors are optimized for wavelengths that include 1064nm, 1030nm, and 1050nm, where our mirrors exhibit >20J/cm2@1064nm, 10ns, and 10Hz pulse damage thresholds. These high-power laser mirror modules are excellent for solid-state pulsed lasers such as the fundamental wavelengths of Nd: YAG lasers or Yb: YAG lasers, etc, ensuring high reflectance for various laser systems and are ideal for nanosecond, picosecond, and femtosecond pulsed lasers, as well as CW laser sources.
