The primary component responsible for producing light in an Intense Pulsed Light (IPL) device is a flashlamp, specifically a xenon flashlamp. When the flashlamp is electrically stimulated, it emits broad-spectrum visible light in short bursts or pulses. This intense light is then filtered to target specific wavelengths suitable for various skin treatments, such as hair removal or skin rejuvenation.

The technology behind IPL capitalizes on the usage of the flashlamp to generate this light, which is crucial for the effectiveness of the treatment. The flashlamp allows for the modulation of the light pulses to provide a range of treatment options for various skin conditions, relying on its ability to produce a wide spectrum of light.

In contrast, while laser diodes and LED arrays can produce light, they operate on different principles and are typically associated with specific wavelengths rather than the broad-spectrum output characteristic of IPL systems. The xenon bulb also functions more similarly to a flashlamp, but in the context of IPL, the flashlamp emphasizes the pulsed nature of the light output, which is essential for its therapeutic applications.
