ABSTRACT

The broad spectral emission from a single laser cavity containing a dye-based gain medium makes these sources attractive for many applications, as described in chapter B5.3 on liquid lasers. A single laser configuration can be used to produce light from the ultraviolet to the near-infrared by merely changing the laser dye in the gain medium. In addition, it is possible to tune the wavelength of the light from a given laser dye over a narrow spectral range, often over a few tens of nanometres.
