Levitated optomechanics

What is Levitated Optomechanics?

Levitated optomechanics is a field of research that involves using light to manipulate and control the motion of small objects, such as micromechanical devices or even individual atoms. This is achieved by creating an optical trap, where a focused beam of light is used to suspend the object in mid-air, allowing it to rotate freely while maintaining a precise position.

History

The concept of levitated optomechanics dates back to the 1990s, when researchers first demonstrated the ability to trap and manipulate individual atoms using laser beams. However, it wasn't until the early 2000s that the field began to gain momentum, with the development of more sophisticated optical trapping techniques.
