Paralight Optics’ Laser Line dielectric mirrors fabricated with specialized coatings that offer high damage thresholds, making them well suited for use with a range of high-powered CW or pulsed laser sources. Our laser line mirrors are designed to withstand the high-intensity beams typically produced by Nd:YAG, Ar-Ion, Kr-Ion, and CO2 lasers.
Paralight Optics offers Nd: YAG Laser Output Couplers with dielectric coatings optimized for T 2%, 5%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 95%, please check the following graphs for your references.

These plots show that each sample of our four dielectric coatings for the different spectral ranges is highly reflective. Due to variations in each run, this recommended spectral range is narrower than the actual range over which the optic will be highly reflective. For applications that require a mirror which bridges the spectral range between two dielectric coatings, please consider a metallic mirror.
