Titanium-Doped Sapphire Lasers with High Energy Pumping

Abstract

A titanium-doped sapphire is pumped with up to 900 mJ of blue-green energy from a dye laser. 8% energy conversion to the near IR is demonstrated. The experimental input/output data agree well with calculations based on the measured characteristics of crystal and pump beam. Analysis of the conversion efficiency reveals the potential to achieve values of about 35% in optimised, but simple, devices.
