The patent refers to one or more droplets of chiral liquid crystals used as point source(s) of laser light. The source is shaped as a droplet of chiral liquid crystals () and an active medium preferably dispersed in the liquid crystals. The source is spherical and with a size of preferably between a few nanometres and 100 micrometres. A droplet consists of chiral liquid crystals () that have selective reflection in the range of the active medium's emission and can be cholesteric liquid crystals, a mixture of nematic liquid crystals and a chiral dopant or any other chiral liquid-crystal phase, preferably the blue phase, the ferroelectric phase, the antiferroelectric phase, any of the ferrielectric phases or another chiral phase of a soft substance, that need not be chiral by itself.
