| Abstract: | Laser ablation bio-tissue is a important performance of laser application.And also is seeking after the effect of laser parameter on ablation efficiency in laser medical.The experiments are used to study ablation effect of vitro pig liver by laser operating at 532nm,1064nm,1320nm,individually.The ablation depths and thermo-damage depths are compared with three wavelengths at different frequency and pulse width.The results indicate that the pulse 532nm laser has the highest ablation efficiency and the minimum damage district among the three wavelengths laser when ablating tissue with abundant blood. |
