Abstract:
1. A skin treatment system comprising: a body having a skin-contacting end; the body having a window through which tissue treating radiation is transmitted to an area of skin being treated; a radiation source which generates a pulse of tissue treating radiation that is transmitted through the window, and wherein the pulse of tissue treating radiation has a pulse amplitude and a pulse duration; and a power supply coupled to the radiation source, wherein the power supply includes a buck regulator circuit which controls the pulse amplitude and the pulse duration of the tissue treating radiation; wherein the radiation source includes a flash lamp; wherein the power supply includes a capacitor which stores an electrical charge, which is transmitted through the flash lamp and the capacitor is coupled to the flash lamp; and wherein the buck regulator circuit includes a switch which is coupled with the flash lamp, whereby an amount of electrical charge current transmitted through the flash lamp is controlled by an opening and closing of the switch.
