Kind: research · Impact: medium

## In brief

- The paper examines the optomechanical limit on intracavity intensities in high-numerical-aperture optical cavities, where continuous-wave intensities above 300 GW/cm² have been reached.
- The authors identify bulk mirror vibrations as the mechanism that constrains these intensities.
- Such intensities are relevant to phase-contrast electron microscopy and ultradeep dipole traps for molecules.

## Why it matters

Ultrahigh intracavity intensities underpin several techniques, so a physical limit set by mirror vibrations defines how far those applications can be pushed.
