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.
