摘要	A system and method for the destruction/ablation of stones, calculi or other hard substances by means of laser energy is disclosed. As a consequence, several important medical treatments can be performed, especially lithotripsy. The system comprises a diode laser source emitting at least at one wavelength, one or more optical fibers which convey laser radiation to the treatment site and a liquid delivery system used for creating a liquid environment around the stones (calculi). The laser device emits at least one wavelength which is highly absorbed in the surrounding/covering medium, thus causing evaporation and cavitation effects that lead to stone/calculi destruction. Different radiation configurations may be used. In one embodiment continuous radiation is used to create sparkler-less plasma bubbles able to destroy hard substances. In another embodiment high peak power pulsed radiation is used. Wavelengths of 1470 nm, 1940 nm, or 1550 nm are preferred.
其他摘要	公开了一种借助于激光能量破坏/消融石块，结石或其他硬物质的系统和方法。因此，可以进行几种重要的医学治疗，尤其是碎石术。该系统包括至少在一个波长发射的二极管激光源，一个或多个将激光辐射传送到治疗部位的光纤和用于在石头（结石）周围产生液体环境的液体输送系统。激光装置发射至少一种在周围/覆盖介质中高度吸收的波长，从而引起蒸发和空穴效应，导致石块/结石破坏。可以使用不同的辐射配置。在一个实施例中，使用连续辐射来产生能够破坏硬物质的无烟火的等离子气泡。在另一个实施例中，使用高峰值功率脉冲辐射。优选波长为1470nm，1940nm或1550nm。 A0
