Light-based devices

Lasers, intense pulsed light, and LED systems, grouped by how their output is specified.

Light-based devices differ in whether the output is a single wavelength (laser) or a filtered broadband spectrum (intense pulsed light), and in whether the energy is delivered continuously or in pulses.

Specifications in this topic are recorded as published: wavelength or filter range, pulse duration, fluence, and spot size. Values expressed as a range in the source document are reproduced as a range.
