Folyadéklézer

Folyadéklézer, also known as liquid laser or dye laser, is a type of laser that uses an organic dye dissolved in a liquid solvent as its gain medium. This allows for tunability, meaning the wavelength of the laser light can be adjusted over a wide range.

The operation of a folyadéklézer involves exciting the dye molecules in the liquid solution using a pump source, which can be another laser, a flashlamp, or even an arc lamp. When the excited dye molecules return to their ground state, they emit photons, leading to stimulated emission and laser light. The properties of the emitted light, such as wavelength and intensity, depend on the specific dye used, the solvent, and the pumping mechanism.

Folyadéklézerek are known for their broad tunability, which is a significant advantage in applications requiring specific wavelengths. They can produce light across the visible spectrum and into the ultraviolet and near-infrared regions. This tunability makes them valuable tools in various scientific and industrial fields.

Applications of folyadéklézerek include spectroscopy, where they are used to identify and analyze substances by their light absorption or emission patterns. They are also employed in photochemistry, medicine (e.g., for dermatology and ophthalmology), and in research settings for fundamental studies of light-matter interactions. The ability to precisely control the emitted wavelength allows for highly selective interactions with materials or biological tissues.
