Patent ID: 7710044

Claim:
A method of generating from at least one flashlamp a series of optical output pulses of a range of wavelengths in the visible spectrum for cosmetological or dermatological purposes, each said optical pulse having a predetermined time interval, which method comprises the following steps: (i) providing said at least one flashlamp with a drive circuit comprising a storage capacitor, switch means comprising an insulated gate transistor, a driver for opening and closing said switch means, and a digital signal processor operatively connected to said driver; (ii) operating said driver under the influence of said digital signal processor so as to selectively open and close said switch means and thereby to respectively selectively and repeatedly charge said storage capacitor and discharge said storage capacitor; and (iii) controlling said discharge of said capacitor so as to deliver to each said flashlamp a plurality of packets of electrical energy each of duration less than, and of high frequency relative to, said predetermined time interval.
