Introduction to Liquid Lasers

Liquid lasers are also called dye lasers, because the active 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 laser light, a high-speed flash lamp is generally used as a laser source, or a very short light pulse is emitted by other lasers. The laser light emitted by liquid lasers is of great significance for spectral analysis, laser chemistry and other scientific research.
