We demonstrate all-optical enhanced highly sensitive Raman spectroscopy that can be versatilely applicable to surface/interfacial ultrathin layers of optical materials without signal enhancements by plasmonic nanostructures and specific electronic resonances. Such spectroscopic innovation was achieved by three-colour coherent anti-Stokes Raman scattering that hybridizes time- and frequency-domain spectroscopic schemes.
