Liquid laser
Liquid lasers are also called dye lasers, because the activating substance of this type of laser is a solution formed by dissolving certain organic dyes in liquids such as ethanol, methanol or water. In order to excite them to emit lasers, high-speed flash lamps are generally used as laser sources, or other lasers emit short light pulses. The laser light emitted by the liquid laser is of great significance for spectral analysis, laser chemistry, and other scientific research.
