Electric fields are a fundamental parameter required for measurement; however, conventional electric field measurement techniques in high-pressure environments, such as atmospheric pressure, face a common challenge: because the signal depends on molecular density, they are difficult to apply to environments where the molecular density is unknown.This study demonstrated electric field measurement in an environment with unknown molecular density using visible-detection electric field-induced coherent anti-Stokes Raman scattering (E-CARSv) with water molecules as a probe. By simultaneously acquiring the molecular density in the signal generation region from the absorption of a mid-infrared laser, this method successfully overcomes the conventional limitation.
