Laser Crystals

Product Description: 

Laser crystal rods are the most important part of pumped solid state lasers. The host materials are chosen to obtain a desired combination of optical, mechanical, and thermal properties. They are doped with ions of chromium (Cr) neodymium (Nd) or titanium (Ti) to provide gain media for the stimulated emission. Recently diode pump laser has replaced flashlamp in many applications in terms of compactness and efficiency. Frequency-doubled technology has enabled the wavelength extended into UV range. The first laser was a small ruby rod that was surrounded by a helical flash lamp. It becomes one of the most important inventions in last century. Ruby is chromium doped sapphire.

We provides high quality neodymium doped yttrium vanadate (ND:YVO4), neodymium doped yttrium aluminum garnet (ND:Y3Al5O12), titanium doped sapphire (Ti3+:Al2O3) and Chromium Doped Yttrium Aluminum Garnet (Cr4+:Y3Al5O12)
