beams of light have never been able to cool liquids
stopped reading there because article is already incorrect
every record breaking cooling achievement has been done by laser cooling

- logfromblammo 11y agoHaven't all those records been broken by cooling gases at a very low pressure? But in this case, the laser is not cooling the liquid. It is cooling a solid crystal of an anti-Stokes phosphor within the liquid. The negative Stokes shift is powered by thermal energy, so the more you make it convert near-infrared to green, the colder it gets. The liquid gets colder because it is touching the crystal. So the article is even wrong on that count. This laser is not cooling a liquid at all. It won't do anything without the anti-Stokes phosphor crystal.
