Cooling mechanical resonators with a microscope

Laser cooling a mechanical resonator The lab has harnessed a new type of coupling between light and mechanical resonator to demonstrate a new technique for cooling–removing mechanical energy–from a nanoscale object. This object was fabricated from a diamond chip and was installed in a custom microscope and cryostat designed for combining laser cooling with nanophotonic…

Nature Communications publication Check out Matt and David’s latest discovery: a technique for interfering light with vastly different different wavelengths. They accomplish this by coupling both optical fields to the same mechanical resonator. The phase of each field affects the motion of the resonator, resulting in an effective interaction between both optical inputs. Two-colour interferometry…
