Abstract

The characteristics of a 940 nm pumped Cr4+:forsterite laser have been investigated using a pulsed colour centre laser as the excitation source. Laser threshold, slope efficiency and temporal behaviour have been determined for high and low Cr4+ doped material. 940 nm pumping is found to be more efficient than 532 and 730-770 nm excitation. Discrepancies with 1064 nm pumping are attributed to excited state absorption. Absorption saturation measurements have been used to assess the potential applications of Cr4+:forsterite, Cr4+:YAG and Cr4+:Lu3Al5O12 (LuAG) as passive Q-switches for Nd lasers in the 940 nm region.
