Overview

Edmund Optics® is an industry leader in laser crystal and glass polishing and coating. Our Florida facility works with a wide variety of materials including YAG, YLF, YALO, KTP, LBO, BBO, YVO4, PPSLT, PPLN, and phosphate-doped glasses. Our precision polishing processes improve coating adhesion, minimizing losses and increasing LIDT.

Laser crystal and doped glass slabs are some of the most popular gain media in solid-state laser sources. They are often doped with transition metal or rare earth ions that amplify input laser light through stimulated emission. Non-linear crystals are used for frequency conversion of laser sources. Laser crystals benefit from less absorption, a narrower emission bandwidth, higher transition cross sections, and higher thermal conductivity compared to doped glasses and other gain media. What can we make for you?
