Record-breaking, floating laser resonator

A new optical resonator has unprecedented in resonance enhancement. A resonator is a device that traps waves and enhances or echoes them by reflecting them from wall to wall in a process called resonant enhancement. Today, there are complex and sophisticated resonators of various kinds throughout the world, as well as simple resonators familiar to all of us. Examples of this include the resonator box of a guitar, which enhances the sound produced by the strings, or the body of a flute, which enhances the sound created in the mouthpiece of the instrument.
