World's first 3D microlaser created, has a gooey Bragg-onion center

Solid-state lasers are fine, durable and reliable and all that, but what if you want something a little softer, maybe a little more conforming to your needs and moods? Or, what if you want something that can beam light in all directions at once? Then you need to go liquid, baby, liquid. That's what Slovenian scientists (and diacritic wunderkinds) Matjaž Humar and Igor Muševič have done, creating, in their words, "3D microlasers from self-assembled cholesteric liquid-crystal microdroplets." Various layers of fluids form what's called a Bragg-onion optical microcavity, including embedded crysta
