Optical Breakdown Threshold in Liquid
Based on the free electron density rate equation, a plasma ellipsoid model was proposed by considering the characteristic of shaping in the focal region. Theoretical breakdown thresholds calculated by plasma ellipsoid model with modifying the electron diffusion rate were presented under the condition of shorter laser pulses. The results show that the breakdown thresholds of water calculated by plasma elliptical model are better in agreement with experimental result than other models.
