| Abstract: | Optical limiting effect of nanosecond laser pulses by stimulated Brillouin scattering is investigated. Optical limiting performances and energy stabilization of 2 ns Nd:YAG laser pulses were studied both theoretically and experimentally in a nonlinear SBS medium CCl4, the influence of parameters of SBS limiter cell on optical limiting effect predicted by theory were conducted, and superior constant output energy was gained with input energy changing in experimental regime. For the ±13% is relative fluctuation of input energy of laser pulses, ±7% relative fluctuation of the transmitted signals was obtained. The experimental results were in good agreement with the predictions by theoretical simulation. |
