= Liquid-crystal laser
{wiki=Liquid-crystal_laser}
A liquid-crystal laser is a type of laser that utilizes liquid crystals as its gain medium or in conjunction with other optical systems to manipulate light. Liquid crystals are materials that have properties between those of conventional liquids and solid crystals. They can change their optical properties (such as refractive index) in response to external influences like electric fields or temperature, which makes them highly versatile in optical applications.
