Computational Simulation of High-Concentration Erbium Media for Lasers Development

Abstract:

Different laser designs may require high-concentration erbium lasers. The laser efficiency can be measured by the small signal gain (SSG) of the laser media. In this paper an investigation of the SSG for a Er:YLF with 40 mol % of erbium concentration were carried out by means of computational simulation considering several pumping rates and different pulse duration . Results showed that the maximum SSG values for 40% Er concentration are reached for lower pulse durations and high pumping rates. In addition, results suggest that the performance of such lasers can be significantly enhanced by the adjustment of pulse duration and the interval between two consecutive pulses.
