Product DescriptionProduct DescriptionYAG Laser Mirrors are precision-engineered optical components designed for high-power Nd:YAG laser systems across 1064 nm (fundamental), 532 nm (2nd harmonic), 355 nm (3rd harmonic), and 266 nm (4th harmonic) wavelengths. Crafted with UVFS or BK7 substrates and advanced coatings like ion beam sputtered (IBS) dielectric layers, they deliver >99.5% reflectivity, low absorption (<5 ppm), and high damage thresholds (up to 25 J/cm2 for 1064 nm pulsed lasers). Ideal for industrial machining, medical devices (ophthalmology, dermatology), and research, these mirrors ensure stability under extreme conditions.As a china manufacturer, we offer tailored solutions including:· Customized coatings (dielectric, gold, silver) for specific wavelengths and angles of incidence (0°–45°)· Rapid prototyping and off-the-shelf availability in ?1/2" to ?2" sizes· Rigorous quality assurance with surface flatness λ/10 and 10-5 scratch-dig standards· Technical support for optimizing laser system efficiency and minimizing scatter lossesOur mirrors integrate seamlessly into pulsed and CW laser setups, ensuring reliable performance in demanding applications.Product OverviewThe 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.SpecificationProduct: YAG Laser MirrorsMaterial: Fused Silica/BK7Diameter Tolerance: +/-0.1mmThickness Tolerance: +/-0.1mmFlatness (PV): <1/10L@632.8nmSurface Quality: 10-5Surface Roughness: Ra<1nmAngular Deviation: <5arcsecClear Aperture: >90%Bevel: Break sharp edgesApplicationsIndustrial Laser ProcessingMedical ApplicationsIdeal 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.Scientific ResearchLaser Marking & EngravingEnables 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.Key FeaturesHigh ReflectivityOur 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. Low Absorption & ScatteringConstructed 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.High Damage ThresholdEngineered 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. Precise Optical SurfaceManufactured 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.
