Optimization of Passively Repetitively $Q$-Switched Three-Level Lasers |
| |
Abstract: | A generalized model of a passively repetitively $Q$-switched three-level laser is presented. The method for evaluation of the small-signal gain coefficient and the dissipative losses of a three-level laser is shown. To demonstrate the use of this optimization procedure, it was applied to a microchip laser generating 1.5- $mu$m radiation. The model may be expanded for a four-level laser by replacing the calculation of the small-signal gain coefficient. |
