Once the stone is seen, a laser fiber is used to transmit Holmium energy to break up your kidney stones. The surgeon removes some pieces through the urethra with a small basket, and smaller pieces can be passed later with urination. The surgeon may also use a high-powered holmium laser with high-frequency emissions that "dust" the stones …

Hafez et al. 18 explored the rupture rate of limestone, sandstone, and shale under laser radiation and its influencing factors. They proposed that a smaller laser beam diameter helps increase the rock breaking rate. Factors such as rock thickness, laser reflection, and water saturation all affect the rate of laser breaking.

X-ray diffraction is a common technique that determine a sample's composition or crystalline structure. For larger crystals such as macromolecules and inorganic compounds, it can be used to determine the structure of atoms within the sample. If the crystal size is too small, it can determine sample composition, crystallinity, and …

For instance, the temperature-increasing rate of limestone irradiated by the laser beam can approach 14 °C/ms [34], which demonstrates that laser irradiation could be classified as a thermal ...
