Abstract
Driving a flash lamp in an Intense Pulsed Light (IPL) system requires a high voltage DC power supply, capacitive energy storage, and a flash lamp triggering unit. Single, double, triple, and quadruple-mesh discharge and triggering circuits were constructed to provide intense light pulses of variable energy and time durations. The system was treated as [Formula: see text] circuit in some cases and [Formula: see text] circuit in others with a light pulse profile follows the temporal behavior of the exciting current pulse. Distributing the energy delivered to one lamp onto a number of LC meshes permitted longer current pulses, and consequently increased the light pulse length. Positive results were obtained when using the system to treat skin wrinkles.
