Paralight Optics offers 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 Harmonic Separators designed for the fundamental, 2nd harmonic, 3rd harmonic, and 4th harmonic of Nd:YAG lasers. Checking the following graphs for dichroic mirrors for your references.
