Researchers use lasers to supercool semiconductor membranes, blow your mind (Engadget)
Ah, lasers. Those wonderful, super intense beams of light that we’ve seen used
in headlights, projectors, and naturally, death rays. Like us, researchers at
the Niels Bohr Institute at the University of Copenhagen figure there’s
nothing lasers _can’t_ do, and have figured out a way to use them to cool a
bit of semiconducting material. This bit of black magic works using a membrane
made of gallium arsenide and is based upon principles of quantum physics and
optomechanics (the interaction between light and mechanical motion).
Turns out, when a one millimeter square membrane of gallium arsenide is placed
parallel to a mirror in a vacuum chamber and bombarded with a laser beam, an
optical resonator is created between them that oscillates the membrane. As the
distance between the gallium arsenide and the mirror changes, so do the
membrane’s oscillations. And, at a certain frequency, the membrane is cooled
to minus 269 degrees Celsius — despite the fact that the membrane itself is
being heated by the laser. So, lasers can both heat things up _and_ cool them
down simultaneously, and if that confuses you as much as it does us, feel free
to dig into …
