Spectral Properties of a Novel Laser Crystal Y(3)(In, Ga)(2)Ga(3)O(12) :Cr(3+)

Abstract

Spectral properties of a novel phonon terminated laser crystal Yttrium(3)(Indium, Gallium)(2)Gallium(3)Oxygen(12): Chromium(3+) grown by the flux method are reported for the first time. The results show that the spectral properties of this novel crystal are compatible with those of Gadolinium)3) (Selenium, Gallium)(3)Gallium(3)Oxygen(12): Chromium(3+) and is a potential ambient temperature tunable laser crystal. Gadolinium(3)(Scandium, Gallium)(2) Gallium(3)Oxygen(12): Chromium(3+) (shortened to GSGG:CR3+) is a type of phonon- terminated laser crystal with excellent capabilities. It has a relatively weak crystal field and relatively strong electron-phonon coupling. At room temperatures a strong terminal phonon emission spectrum with a half width of about 100 nm can be observed. At the same time, experimentally at room temperatures, a wide band continuous tunable laser emission has been observed. Since it has been reported, a great deal of attention has been paid to it. However, since Scandium is rare and expensive its applications are limited.
