Abstract
A new ultraviolet excitation route for chromium forsterite lasers is i nvestigated. Enhanced gain with simultaneous 1064 nm infrared and 266 nm ultraviolet pumping leads to a 10-20% increase in the forsterite pu lse energy, compared to the 1064 nm only case. A quantum efficiency of 0.6 is inferred for ultraviolet excitation. The results have signific ant implications for efficiency and practicability of flashlamp-pumped and high-power systems.
