Study of a Mode Separation Due to Polarization Existing in a Cavity-Enhanced Absorption Spectroscopy
A special phenomenon of resonance mode separation is observed during the study of a high sensitivity folded-cavity enhanced absorption spectroscopy for the measurement of trace gases. The phenomenon affects the measurement of gas absorption spectrum in the cavity. This resonant mode separation pheno...
