Abstract
An IPL apparatus utilizing a Pulse Forming Network (PFN) for generating a plurality of light pulse sequences, comprising a treatment unit comprising one or more lamps adapted to emit a plurality of light pulses towards a treatment face of the IPL apparatus, a PFN and a control unit adapted to operate the PFN to generate a regulated energized pulse driven to the lamp(s). The regulated energized pulse having a desired multi-level voltage waveform with a maximum voltage level and a minimum voltage level which is in a range of 30-50 percent of the maximum voltage level. Rapidly varying heat is induced by a sequence of the plurality of light pulses emitted by the lamp(s) according to the multi-level voltage waveform.
