Abstract

Chromium-activated forsterite (Cr:Mg2SiO4) is a new broadly frequency-tunable vibronic solid-state laser in the near-IR region.1,2 Room-temperature pulsed and cw laser action has been obtained in this system for both 532- and 1064-nm excitation from a Nd:YAG laser. However, the identity of the lasing center in Cr:forsterite has not yet been established with certainty. Although trivalent chromium (Cr3+) is the active ion in all the chromium- based solid-state lasers reported to date, indications are that this system is an exception.
