• 論文の詳細を見る

• Sensitive sub-Doppler resolution molecular spectroscopy developed by Hall and co-workers [J. Opt. Soc. Am. B 15 (1998) 6] has been applied to the 1.66 μm region using a widely tunable external-cavity diode laser. We have recorded saturated absorption spectra of the 2ν_3 vibrational overtone band of methane with a sensitivity of 9.5×10^<-11> cm^<-1> at a time constant of 1.25 s and a spectral linewidth of 320 kHz (full width at half maximun ; FWHM) over the tunable range of 1.63 to 1.68 μm.
