Abstract

Emerald [Cr3+:Be3Al2(SiO3)6], a trivalent chromium-activated beryl is one of the earlier vibronic frequency-tunable laser crystals,1,2 which stimulated the recent surge in tunable solid-state laser research. Emerald, like alexandrite, operates in a four-level mode at room temperature over the 695-835 nm wavelength range. The broad absorption bands at 615 nm and 416 nm due to transitions from the 4A2 ground state to the 4T2 and 4T1 states of the Cr3+ ion serve as pump bands for optical excitation.
