Optomechanics

Optomechanics is the use of laser light to control the motion of mechanical vibrations, usually micrometre- or nanometre-scale resonators. As well as probing micromechanical motion, light can also remove energy from the system. In this way, an oscillator can reach the quantum limit with just one quantum of vibration energy, or phonon.
