Abstract
In this paper, the signal output power of an intracavity optical parametric oscillator is optimized so that the signal output power becomes maximum. The particle swarm optimization (PSO) algorithm is implemented to some practical setups and the results are compared with some experimental data in order to confirm our method. Finally, the PSO algorithm is performed on the rate equations to obtain and suggest the optimum values for gain medium length, nonlinear crystal length and output coupler reflectivity at signal wavelength simultaneously, in which the largest signal output power can be obtained. The numerical results show that at 25.9W for input power, the signal output power can be reached up to 4.55 W. In addition, the signal output power can be increased by 20%, by selecting appropriate values for the gain medium length, nonlinear crystal length and output coupler reflectivity at signal wavelength.
