Excitation of a Cr:forsterite laser to the T-3(1) band

摘要

Laser oscillation of Cr:forsterite was obtained with ruby laser pumping to the lowest-lying levels of the T-3(1) band in Cr4+. Pump polarization effects, temporal response, and broadband 220-nm tuning are reported. Frequency doubling in potassium titanyl phosphate generate tunable red-yellow light. This unconventional excitation scheme is of interest for potential high-energy output and for direct diode pumping. (C) 1997 Optical Society of America.
