Overview

IREEDA High-Precision Output Mirror is a critical optical component designed for laser resonators and beam delivery systems. It serves as the exit port for the laser cavity, allowing a specific percentage of 1064nm laser power to be transmitted while simultaneously handling the alignment red light (650nm).

Crafted from premium K9 (BK7) or Fused Silica (Quartz), these mirrors feature advanced multi-layer dielectric coatings. The design is optimized for dual-wavelength performance: 85% transmission at 1064nm for maximum output efficiency and 15% reflection at 650nm to facilitate coaxial red light aiming and positioning.
Highlights

• Dual-Wavelength Optimization: Unique coating design allows 85% of the 1064nm main laser to pass through while reflecting 15% of the 650nm pilot beam, ensuring perfect coaxial alignment.

• Ultra-Low Loss AR Coating: The reverse side is treated with an AR coating (R < 0.2% @ 1064nm), significantly reducing back-reflection and protecting your laser source from feedback damage.

• Industrial Grade Substrates: Choice of K9 for cost-effective applications or Fused Silica (Quartz) for high-power lasers requiring exceptional thermal stability and a high laser damage threshold (LDT).

• Precision Manufacturing: Tight tolerances on diameter (+0/-0.1mm) and high-quality surface finish (20/10 Scratch-Dig) ensure minimal beam distortion and long-term reliability.

• Fully Customizable: We offer flexible customization for sizes (ϕ20, ϕ12.7, or bespoke), transmission/reflection ratios, and specific wavelength coatings to match your system requirements.
