We demonstrate a bi-chromatic pump-probe spectroscopy comparison between conventional cm-size Cs-filled cell and cells with thickness miniaturized down to 5.2 μm and 700 μm. In the 5.2 μm cell very-good-contrast enhancedtransparency- resonances were obtained that can be efficiently suppressed (controlled) with small about 31 MHz detuning of the pump laser frequency. The resonances do not move their spectral position with the pump frequency detuning like it is in the classical cm-size cells. Miniaturization down to 700 μm does not compromise the enhanced-transparencyresonances. In addition, at that level of miniaturization, the probe beam transmission spectra show as narrow features as in classical cm-size cells. Comparison of the obtained coherent resonances in 700 μm cell with that in 2.5 cm shows no broadening and both have resonance width limited by the emission linewidth of the used pump and probe lasers.
