Liquid Lasers

Type: Technology

As of November 2026, Liquid Lasers has been mentioned in one podcast episode on Stuff You Should Know (Feb 2026). Discussed as dye lasers using organic dyes as gain media, notable for tunability across wavelength ranges.

A liquid-crystal laser is a laser that uses a liquid crystal as the resonator cavity, allowing selection of emission wavelength and polarization from the active laser medium. The lasing medium is usually a dye doped into the liquid crystal. Liquid-crystal lasers are comparable in size to diode lasers, but provide the continuous wide spectrum tunability of dye lasers while maintaining a large coherence area. The tuning range is typically several tens of nanometers. Self-organization at micrometer
