Scientists in Slovenia have developed a microlaser that is said to be the world's practical, three-dimensional laser. Detailed in an Optics Info Base report (PDF), the device is made of self-assembled cholesteric liquid-crystal microdroplets. In it, laser light is emitted in all directions from dye molecules lodged within spherical drops of helical molecules dispersed in a liquid....
