# Optomechanical cooling with intracavity squeezed light

## TL;DR

This paper demonstrates that intracavity squeezed light can significantly improve optomechanical cooling efficiency, especially outside the resolved sideband regime, by suppressing Stokes scattering more effectively than external squeezing methods.

## Contribution

It introduces a novel intracavity squeezing scheme that enhances optomechanical cooling beyond traditional methods, including in non-resolved sideband regimes.

## Key findings

- Enhanced cooling efficiency with intracavity squeezing
- Suppression of Stokes scattering via coherent interference
- Effective cooling outside the resolved sideband regime

## Abstract

We analyze the performance of optomechanical cooling of a mechanical resonator in the presence of a degenerate optical parametric amplifier within the optomechanical cavity, which squeezes the cavity light. We demonstrate that this allows to significantly enhance the cooling efficiency via the coherent suppression of Stokes scattering. The enhanced cooling occurs also far from the resolved sideband regime, and we show that this cooling scheme can be more efficient than schemes realized by injecting a squeezed field into the optomechanical cavity.
