Paper Abstract

A numerical model of an all-fiber Nd3+ laser passively Q-switched with Cr4+ is presented. The repetition rate, average output power, and pulse width have been calculated with the same parameters as those of an experimental setup of another group. We found a qualitative agreement between the two results. The validated model has been used on another proposed setup to investigate and optimize laser parameters. The low and high self-impulse amplitude regimes were found for different Cr4+ ion densities. The optimal efficiency of the high regime was established when the saturable absorber density increases.
