| الوصف: | International audience ; Comparison of absorption and fluorescence in a nano-cell containing Rb vapor with other Rb nano-cells where neon gas is added is presented. The effect of collapse and revival of Dicke-type narrowing is still observable for the Rb nano-cells where Ne gas is added under 6 and 20 Torr pressure for the thickness L=/2 and L=, where is a resonant laser wavelength 794 nm (D1 line). Particularly for 6 Torr the line-width of the transmission spectrum for the thickness L=/2 is 2 times narrower than that for L=. For an ordinary Rb cell with L = 0.1 - 10 cm with addition of buffer gas, the velocity selective optical pumping/saturation (VSOP) resonances in saturated absorption spectra are fully suppressed when the buffer gas pressure > 0.5 Torr. A spectacular difference is that for L=, VSOP resonances located at the atomic transition are still observable even when Ne pressure is ≥ 6 Torr. Narrowband fluorescence spectra of the nano-cell with L= λ/2 can be used as a convenient tool for online buffer gas pressure monitoring for the conditions when ordinary pressure gauges are unusable. Comparison of electromagnetically induced transparency (EIT) effect in a nano-cell filled with pure Rb with another nano-cell, where buffer gas nitrogen is added, is presented. Use of gas N2 inside the Rb nano-cell strongly extended the region of the coupling laser detuning where EIT resonance is still possible to form. |
