The need for comfortably operable, precise, and in their color settable sources of light for the optical spectroscopy in research and industry is enormous due to the range of applications. For analyses in nuclear physics to environmental technology, dye lasers are the ideal source of radiation. However, they are so large, complicated in usage, and cost and maintenance intensive that their use has so far been limited to niche applications. Users therefore use systems, which filter out the required light from white light as an alternative. These systems work inefficiently and are not implementable for all applications.
