In laser: Types of lasers
In dye lasers the laser medium is a liquid containing organic dye molecules that can emit light over a range of wavelengths; adjusting the laser cavity changes, or tunes, the output wavelength. Chemical lasers are gas lasers in which a chemical reaction generates the excited molecules…

In spectroscopy: Laser spectroscopy
…source is provided by the dye laser, in which laser emissions arise from the decay of dye molecules that have been excited into a multitude of closely spaced rovibronic (rotational-vibrational-electronic) levels by the application of an intense secondary laser signal (a process known as pumping). Dye lasers can provide radiation…
