Molecular Science in Optical Cavity

1. Intermolecular interaction

• Molecular clusters in a supersonic jet are probed by “cavity ringdown spectroscopy”.
• Macroscopic cm-sized cavity with super mirrors of 99.99% reflection.

 

2. Light-matter strong coupling

• Gas-phase vibrational polaritons will be probed by “cavity transmission spectroscopy”.
• Microscopic um-sized cavity with ordinary mirrors of ~90% reflection.
