| Abstract: | A passively Q-switched Nd:YAG laser using a semi-insulating GaAs is demonstrated. The laser characteristics, such as the threshold, single pulse energy and the pulse width were measured. Meanwhile, The saturable absorption dynamics is studied based on the energy-level structure. The rate equations and their numerical solutions for GaAs as passive Q switch were given. The experimental and theoretical results are compared and discussed. |
