The principles of dye laser operation and the experimental techniques that are used to generate high power continuously tunable narrowband dye laser radiation, are extensively reviewed.

The basic physical processes that occur in laser dyes are covered, and rate equation models that are used to explain the operation of CW and pulsed dye lasers.

A dye laser is a laser which uses an organic dye as the lasing medium, usually as a liquid solution. Compared to gases and most solid state lasing media, a dye can usually be used for a much wider range of wavelengths, often spanning 50 to nanometers or more. The wide bandwidth makes them particularly suitable for tunable lasers and pulsed lasers.

Laser - Laser - Fundamental principles: Laser emission is shaped by the rules of quantum mechanics, which limit atoms and molecules to having discrete amounts of stored energy that depend on the nature of the atom or molecule.

The lowest energy level for an individual atom occurs when its electrons are all in the nearest possible orbits to its nucleus (see electronic configuration). We report the generation of fs pulses with nJ energy; the pulses are tunable in the UV spectral range.
