Laser crystals, glasses, and ceramics are used as optical gain sources in solid-state lasers. These media are typically doped with rare-earth ions (e.g. neodymium, ytterbium, or erbium) or transition metal ions (titanium or chromium).
4Lasers develops and supplies 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.
