The YAG Laser Mirror is a critical optical component designed to optimize the performance of YAG laser systems across industrial, medical, and research applications. Engineered with advanced thin-film coatings and precision substrates, it ensures minimal energy loss, superior beam stability, and long-term reliability in high-energy environments. Key functionalities include reflecting fundamental (1064 nm) and harmonic wavelengths (532 nm, 355 nm) with exceptional efficiency, while maintaining strict optical tolerances to support accurate laser beam delivery. Its robust design withstands intense thermal and mechanical stresses, making it an ideal choice for both continuous-wave (CW) and pulsed laser setups.
Our YAG Laser Mirror achieves industry-leading reflectivity through proprietary coating technology, optimized for YAG laser wavelengths:
1064 nm (Fundamental): ≥99.8% reflectivity (@0° incidence, tested to ISO 13697 optical coating standards), minimizing energy dissipation in the laser cavity.
532 nm (Second Harmonic): ≥99.5% reflectivity, ensuring efficient conversion for green laser applications.
355 nm (Third Harmonic): ≥99.0% reflectivity, supporting high-precision ultraviolet laser processes.
In a 200W industrial laser system, this mirror reduces energy loss by 0.3W compared to standard alternatives, enhancing energy utilization by 15%. A precision welding client reported a 20% improvement in weld penetration consistency and a 3.8% reduction in material waste (from 5% to 1.2%) when using our mirror in 1mm stainless steel welding.
Constructed from high-purity fused silica (absorption coefficient ≤0.05% at 1064 nm, ASTM F2157 certified), the mirror minimizes thermal distortion even under prolonged operation. Its ultra-smooth surface (Ra ≤0.2nm, measured via Zygote 6000 scatterometer) reduces scattering loss to ≤0.1%, maintaining beam quality integrity. Thermal stability tests show a maximum temperature rise of 5°C after 8 hours of continuous operation at 150W (25°C ambient), far below industry averages.
In semiconductor semiconductor wafer dicing, a leading manufacturer saw a 2.5% reduction in edge chipping (from 3% to 0.5%), directly attributed to the mirror’s low-scatter surface, improving wafer yield and reducing post-processing costs.
Engineered for high-power environments, the mirror features:
Pulsed Laser Threshold: ≥500 MW/cm² (10ns pulse, 10Hz repetition rate, ISO 21254 compliant), outperforming standard mirrors by 20%.
Continuous Wave Tolerance: ≥300W/cm² sustained power without coating degradation, ensuring reliability in 24/7 industrial operations.
Service Life: Exceeds 10,000 hours under rated power—30% longer than conventional models—reducing maintenance frequency and downtime.
A automotive parts manufacturer using 2kW YAG lasers for metal cutting reported a 40% reduction in coating replacement costs, with service life extending from 6 to 10 months, demonstrating tangible ROI through reduced operational interruptions.
Manufactured to nanometer-level precision, the mirror meets strict optical specifications:
Flatness: λ/10 @ 632.8nm (ZYGO GPI-XP interferometer tested, ISO 10110-5 compliant), ensuring collimated beam reflection.
Surface Roughness: Ra ≤1nm (AFM-measured), minimizing aberrations that could distort beam profiles.
Angular Deviation: ≤5 arcsec from nominal normal, critical for maintaining beam alignment in complex optical paths.
In a research-grade Raman spectrometer, integration of our mirror improved spectral resolution from 0.5nm to 0.3nm, enabling detailed molecular structure analysis in material science applications.
We offer tailored solutions to meet unique application requirements:
Medical-Grade Thin Mirrors: 12mm diameter, 1mm thickness for ophthalmic lasers, FDA 510(k)-certified for safe use in intraocular procedures like posterior capsulotomy.
High-Temperature Resistance: Oxide-zirconia substrate with Al₂O₃ composite coating, tested to 1000 hours at 80°C without performance degradation, ideal for laser heat treatment systems.
UV Wavelength Specialization: 213nm fourth-harmonic mirror with 98.5% reflectivity, successfully deployed in fluorescence spectroscopy for trace chemical detection.
Ideal for high-precision cutting, welding, and marking of metals (stainless steel, aluminum), plastics, and ceramics. In 2kW laser cutting of 5mm carbon steel, the mirror’s high damage threshold and low scatter enable cutting speeds up to 1.2m/min with a heat-affected zone ≤50μm.
Supports minimally invasive surgeries (e.g., YAG laser lithotripsy) and aesthetic treatments. The FDA-compliant thin mirror design fits compact surgical handpieces, delivering precise energy to ocular tissues or skin targets with minimal collateral damage.
Enables advanced experiments in spectroscopy, interferometry, and material ablation. A university research lab used our customized 355nm mirror to achieve 10nm-resolution ablation in polymer thin-film analysis, surpassing previous limits.
Ensures sharp, repeatable marks on metals and plastics. At 50kHz pulse frequency, the mirror’s precise surface allows 50μm-wide text engraving on titanium alloy, meeting aerospace traceability standards.
