Liquid crystal (LC) lasers use a layer of chiral nematic liquid crystal to form a self-organising resonant cavity. When doped with fluorescent dye and suitably excited, they form versatile micro-lasers with high efficiencies, low thresholds, and selective wavelength emission across a continuous range of the visible spectrum. This, combined with their scalable fabrication, makes them attractive candidates for a wide variety of photonic applications, including laser displays. This paper includes a review of the principles of operation, of recent enhancements that are advancing the technology closer to market, and concludes with demonstrations of LC lasers used for medical imaging and low-speckle holography.
