| Abstract: | The behavior of passive Q switching with a slow saturable absorber is analyzed. From the simplified rate equations for passive Q switching, the criteria for passive Q switching using a saturable long recovery time and excited state absorption, and the analytical formulas for the peak power, pulse energy, pulse width and energy extraction efficiency are derived. The general results have applications in the optimal design of such passive Q switched lasers. |
