Intense Pulse Light (IPL) and Extended Theory of Selective Photothermolysis

IPL (intense pulsed light) is light, and not a laser. Unlike laser, in IPL, there is no laser medium nor optical cavity, and only a flash lamp, which is an external energy source (pumping system), exists (Table 9.1). When electricity flows through the xenon gas of the flash lamp, a very bright, high-power light is generated [1].
