Abstract

Laser lithotripsy has clinically been implemented to treat urinary stone disease by using a Ho:YAG laser system. Bubble dynamics plays an important role in determining stone ablation efficiency. The current study developed a two-phase opto-thermal model to numerically assess the bubble dynamics during laser irradiation. The simulation involved light propagation, light and water interaction, and multi-phase heat and mass transfer. The simulation was verified by the experimental setup including Ho:YAG lasers, fiber in water, and high-speed camera. Both the numerical simulations and the experimental results showed a good agreement in predicting the effects of laser pulses on the bubble dynamics.
