Laser treatment of warts and skin growths - uses one millisecond maximum duration impulse at about ten microns

摘要

The process is particularly for the treatment of warts, and consists in submitting the wart concerned to one or more laser impulses of a maximum duration of 1 millisecond, and with a wavelength between approximately 5 and 15 microns. The impulse energy can be between 10 millijoules and 1 joule, the power being at least 1 Mw per sq.cm. The healthy tissue adjacent to the wart can be isolated from the laser beam bundle, whose cross-section can be equal to that of the wart surface. Typically, an iris-type diaphragm can be used for isolating the healthy tissue.
