Contaminant-free end-capped and single-mode acetylene photonic microcell for sub-Doppler spectroscopy

چکیده
We report on the development of an acetylene-filled photonic microcell based assembly process that is contaminant free and requires no helium buffer gas nor gluing procedure. The consists a 7-m-long 30 µm core-diameter inhibited-coupling guiding hollow-core crystal fiber filled with acetylene at pressure in range 80 µbar, sealed by capping its ends fusion-collapsing glass-tube sleeve, mounted FC connectors for integration. shows robust single-mode behavior total insertion loss ? 1.5 d mathvariant="normal">B . spectroscopic merit formed tested generating electromagnetic induced transparency saturated absorption R13 P9 lines, respectively. sub-Doppler transparencies show close to transit time limited linewidth 17 ±<!-- ± <mml:mn>3 mathvariant="normal">M mathvariant="normal">H mathvariant="normal">z latter was monitored over 3 months.

Doppler-free Fourier transform spectroscopy.
Sub-Doppler broadband multi-heterodyne spectroscopy is proposed and experimentally demonstrated. Using two laser frequency combs of slightly different repetition frequencies, we have recorded Doppler-free two-photon dual-comb spectra of atomic rubidium resonances of a width of 6 MHz, while simultaneously interrogating a spectral span of 10 THz. The atomic transitions are uniquely identified via...
متن کاملSub-Doppler tunable far-infrared spectroscopy.
The first experimental observations to our knowledge of sub-Doppler linewidths in a cell made using tunable far-infrared radiation are reported. A double-resonance scheme has been used, combining CO(2)-laser infrared radiation with tunable far-infrared radiation to observe a sub-Doppler line shape in an excited vibrational state of CH(3)OH.
