Nd: YAG Laser Harmonic Separator

Mirrors are an important part of optical applications. They are commonly used to fold or compact an optical system. Standard and precision flat mirrors feature metallic coatings and are good all-purpose mirrors that come in a variety of substrates, sizes and surface accuracies. They are a great choice for research applications and OEM integration. Laser mirrors are optimized to specific wavelengths and use dielectric coatings on precision substrates. Laser mirrors feature maximized reflection at the design wavelength as well as high damage thresholds. Focusing mirrors and a wide variety of specialty mirrors are available for customized solutions.

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.
