Experimental investigation of recording of dynamic holograms within absorption contour of resonant atomic medium

The influence of the atomic concentration, the spectral width of the recording radiation and the resonance detuning on the diffraction efficiency of dynamic holograms recorded on the resonance lines of metals were studied. The efficiency of resonant dynamic holograms is investigated as function of the exposure for different vapor concentrations and resonance off-tuning. Good agreement is noted between the experimental and theoretical results. A region is identified in which the required tuning accuracy is determined by the spectral width of the recording radiation, which makes it possible to use a significantly wider group of radiation sources to record resonant dynamic holograms.
