What is a Laser Mirror?
A laser mirror is a highly specialized optical component engineered to reflect laser beams with maximum efficiency and minimal distortion. Unlike standard mirrors, laser mirrors are coated with precision dielectric layers designed to handle high power densities, specific wavelengths, and maintain beam quality.
At LaserChina, we manufacture laser mirrors that exceed industrial expectations—trusted by laboratories, OEM manufacturers, and laser system integrators globally.
Why Laser Mirrors Matter in Advanced Laser Systems
Laser mirrors are not just reflective surfaces—they are critical for beam alignment, redirection, and stabilization. Their design determines:
-
Reflectivity efficiency
-
Damage threshold
-
Beam divergence control
-
Thermal resistance
Without a high-quality laser mirror, even the most advanced laser systems can suffer energy loss, misalignment, or optical damage.

How to Choose the Right Laser Mirror
Here’s what to consider before purchasing:
1. Wavelength Compatibility
Make sure the mirror’s coating is optimized for your laser’s output.
2. Angle of Incidence (AOI)
Most coatings are optimized for 0°, 45°, or custom AOIs. Misalignment leads to reflectivity loss.
3. Substrate Material
Choose based on heat resistance and thermal expansion: fused silica for high stability, silicon for IR use.
4. Laser Power
High-power systems need mirrors with a high laser damage threshold.
5. Polarization
Ensure coatings support your laser’s polarization (s- or p-polarized light).
Frequently Asked Questions (FAQs)
Q1: Can laser mirrors handle femtosecond or ultrafast lasers?
Yes, our ultrafast laser mirror are engineered with ultra-low group delay dispersion (GDD) coatings to preserve pulse integrity.
Q2: Do these mirrors work with CO₂ lasers?
Absolutely. We offer ZnSe and Si-based mirrors specifically designed for 10.6 μm wavelength compatibility.
Q3: What’s the difference between dielectric and metallic mirrors?
Dielectric mirrors offer higher reflectivity and damage thresholds, while metallic mirrors provide broader spectral reflectance.
