FIELD: physics, optics.
SUBSTANCE: solution relates to a laser radiation source, the resonator of which is a droplet of chiral liquid crystals. The source has the shape of a spherical droplet. The droplet contains a dispersed active medium. The droplet consists of chiral liquid crystals, having a property of selective reflection in the emission range of the active medium.
EFFECT: enabling use of a droplet of cholesteric liquid crystals as a Bragg-type optical 3D microresonator.
