摘要:Taking into account the turn off time of the Q-switch, the coupled equations for a mid-infrared KTiOAsO4optical parametric oscillator (OPO) are given. These rate equations are solved numerically and some key parameters for designing the laser system are determined. The key parameters include the optimal coupling and nonlinear crystal length which maximize the output power and OPO conversion efficiency. We found that a low-loss singly resonant OPO cavity not only enhances the mid-infrared output but also decreases the optimal OPO crystal length. © 2013 Astro Ltd.
