| Research Abstract |
Novel frequency-comb interference spectroscopy is successfully developed, which includes optical frequency-comb and single wavelength laser rays and utilizes their interference(beat) signals. A specific signal measured in one shot of a high-pressure Ar plasma reveals a fine absorption spectrum of Ar metastable atoms. This method is not limited for use in plasma diagnostics, and can be applicable to general diagnostics of fine optical frequency spectra with high accuracy.
