Influence of Focal Length on Optical Limiting Characteristics Based on Stimulated Brillouin Scattering in CCl4 Medium
The influence of focal length on optical limiting power characteristics based on stimulated Brillouin scattering in CCl4 medium is investigated numerically and experimentally. The simulation results show that, the characteristics of limiting power and pulse shape are controlled mainly by focal length when other parameters are fixed. When focal length is short, for example 5cm, the characteristic of limiting power and pulse shape is close to ideal. In experiment, focusing 8ns, 1064nm, 16mJ pulses into CCl4 medium, the rules of limiting power and pulse shape versus focal length are investigated. The experimental results are in good agreement with the conclusions of theoretical simulations.
