Laser crystals

Laser crystal - the active laser medium is the source of optical gain within a laser. Laser crystals or laser glasses typically are doped with rare-earth ions (e.g. neodymium, ytterbium, or erbium) or transition metal ions (titanium or chromium).
In order to fire a laser, the active gain medium must be in a nonthermal energy distribution known as a population inversion.

4Lasers is developing different laser crystal hosts and ion dopant combinations for fundamental, applied research and industrial applications. Available crystal growth techniques: Stepanov, Modified Flux growth, Kyropoulos and Czochralski.

We have capabilities to grow various dopant concentration of these laser crystals:
