Abstract
An investigation was made of the operation of a gain-switched chromium -doped forsterite crystal laser pumped by radiation from a quasi-cw YA G:Nd laser. Optimisation of the cavity parameters made it possible to attain a 55 mu J threshold energy of the pump pulses and a slope effic iency of 10%. Estimates were obtained of the excited-state absorption cross section at the pump frequency and of the influence of this cross section on the slope efficiency.
