dye laser
A dye laser is a laser that 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 100 ...

A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid as in dye lasers or a gas as in gas lasers. Semiconductor-based lasers are also in the solid state, but are generally considered as a separate class ...

laser dye
Laser dyes are dyes used as laser medium in a dye laser. Laser dyes include the coumarins and the rhodamines. Coumarin dyes emit in the green region of the spectrum, whereas rhodamine dyes are used for emission in the yellow-red. The color emi ...
-doped organic matrix such as
poly(methyl methacrylate) (PMMA), rather than a liquid solution of the dye. An example is
rhodamine 6G
Rhodamine 6G is a highly fluorescent rhodamine family dye. It is often used as a tracer dye within water to determine the rate and direction of flow and transport. Rhodamine dyes fluoresce and can thus be detected easily and inexpensively with ...
-doped PMMA. These lasers are also referred to as solid-state
organic laser
Organic lasers use an organic (carbon based) material as the gain medium. The first organic laser was the liquid dye laser. These lasers use laser dye solutions as their gain media.

Organic gain media
In the 1990s, new forms of improved PMMA, such as modified PMMA, with high optical quality characteristics were introduced. Gain media research for SSDL has been rather active in the 21st century, and various new dye-doped solid-state organic matrices have been discovered. Notable among these new gain media are organic-inorganic dye-doped polymer-nanoparticle composites.
An additional form of organic-inorganic dye-doped solid-state laser gain media are the
ORMOSILs.
High performance solid-state dye laser oscillators
This improved gain medium was central to the demonstration of the first tunable narrow-linewidth solid-state dye
laser oscillators, by
Duarte,
which were later optimized to deliver pulse emission in the kW regime in nearly diffraction limited beams with single-longitudinal-mode
laser linewidths of
≈ 350 MHz (or
≈ 0.0004 nm, at a laser wavelength of 590 nm).
These tunable laser oscillators use
multiple-prism grating architectures yielding very high intracavity dispersions that can be nicely quantified using the
multiple-prism grating equations.
Distributed feedback and waveguide solid-state dye lasers
Additional developments in solid-state dye lasers were demonstrated with the introduction of
distributed feedback laser designs in 1999 and distributed feedback waveguides in 2002.
