Abstract
In this work a multi-objective Simulated Annealing algorithm (SA) is applied to maximize the small signal gain (SSG) of Er3+-3µm: YLF crystal, which plays important role in the laser systems development (and further operation). For this purpose the rate equations Er:YLF crystal were solved numerically and 3 microns SSG for different Er3+ concentrations was maximized by Simulated annealing (SA) technique taken into account the pulse time (time-ON), time-OFF and the pumping rate (Rp) parameters. Results show that is possible to obtain valid laser gain for erbium concentration smaller than 9 mol % for the Er:YLF system after appropriate set of these parameters.
