Research Abstract	A novel technique of lithotripsy was investigated with a mid-infrared tunable pulsed laser using difference-frequency generation (DFG). It was found that the principal components of the gallstones were different for the different patients and that the gallstone samples used in this research could be classified into four groups. This is suggested that the gallstones could be efficiently ablated by tuning the wavelength of the laser to the strong absorption peak of the gallstones. However, the loss of laser power and weakness of fiber probe were problems.
