Excitation of a Cr:forsterite laser to the (3)T(1) band.
Laser oscillation of Cr:forsterite was obtained with ruby laser pumping to the lowest-lying levels of the (3)T(1) band in Cr(4+). 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.
