Optimization of passively ruby laser pulse width Q-switched by Cr:YSO solid state saturable absorber.

Abstract

The optimization of simulation ruby laser passively Q-switched with Cr:YSO solid state saturable absorber have been investigated numerically, using constrained Rosenbrock optimization technique. The output pulse width is 23.46 ns. The optimum values of some rate equations parameters (γc, γa and β) were found under the optimization technique. The relation of γc parameter with Cr:YSO solid state saturable absorber molecules number and pulse width have been predicted.
