| Abstract | ||
| Urinary stone fragmentation with long pulsed Ho:YAG laser (wave length equal 2.1 μm) and Er:YAG laser (wave length equal 2.94 μm) investigated in this paper. Fragmentation efficiency of these two lasers is measured by using various energy settings. Laser induced crater depth and ablation volume for both lasers were examined and compared using mathematical model. Theoretical results were compared with experimental results obtained by Hyun Wook Kang. The study shows that the theoretical results and experimental results are comparable, and the crater depth when using Er:YAG laser was more than that on Ho:YAG laser. | ||
