Title:
OPTICAL TWEEZER PHONON LASER
Document Type and Number:
WIPO Patent Application WO/2022/055564
Kind Code:
A3
Abstract:
An optical tweezer phonon laser system and method for modulating mechanical vibrations of an optically levitated mechanical oscillator to produce coherence is disclosed. A feedback loop is configured to simultaneously supply an electro-optic modulator with an amplification signal and a cooling signal representing an amplification force linear in the mechanical oscillator momentum and a cooling force nonlinear in the mechanical oscillator variable position and linear in the momentum, respectively controlling the intensity of a trap beam levitating the mechanical oscillator.
