Semiconductor lasers, being tunable radiation sources, can be successfully used to write, and investigate the properties of, resonant dynamic holograms in the near IR, which is the range of the spectra and of their applications. Such lasers can be used to form transmission and reflection DH with specified properties (energetic, spectral, spatiotemporal). DH written in the bulk of a medium under optical pumping of hyperfine sublevels of the ground state or under selective action of the writing light field on individual atom-velocity groups can be used for conversion of low-intensity (∼10−2 W/cm2) rapidly varying optical signal with nearly planar wave fronts. A volume containing vapor can be heated (if cesium vapor is used) at near-room temperature. Reflection DH, whose features are absence of angle selectivity and a practically uniform SFC, are of interest because they can be used to transform optical signals having wide spatial-frequency spectra and process the images in real time, but have a lower sensitivity and require appreciable heating of a vapor-filled volume. Promising for practical tasks is the us of higher-power lasers to record resonant DH (∼1 W) [45], and also the possibility of using non-single-mode emitters to tune of the longitudinal modes to resonance with the absorption line [33].
