Resonance Methods for Increasing
Sensitivity of Interferometry,
Fluorescence, Dynamic Holography
Coherent-optical—holographic [1–4], interference [5–12] and fluorescent [13–15]
methods make different demands to the light source depending on the tasks: By
considerable energy output and power of the radiance, it can be its high spatial coherence and monochromaticity; tunable wavelength in a broad spectral range, two and
more generation lines of the radiance with the controlled spectral interval, different
width of pulse generation of the radiance, and also generation of two or several pulses
with the controlled time interval, the radiance with given and changeable direction
of vector polarization and so on.
At the heart of the studies, which are presented in the first chapter, are the
phenomena of anomalous dispersion. In the studies of these phenomena, D. S.
Rozhdestvensky [12, 16–26] discovered a lot of interesting things, particularly, his
studies became the continuation of his school.
The results of the studies on resonance optics, which include dynamic resonance holography, resonance interferometry and fluorescence are given in the present
chapter. Resonance methods [27–29], which enable to regulate the medium sensitivity to the recording of dynamic resonance gain-phase (bulk and plane) holograms
are also proposed and experimentally carried out in this chapter. Thereby these resonance methods reveal a new class of detecting media for dynamic holograms—
gaseous medium [30–35], and also they allow raising enormously the sensitivity of
interferometry and fluorescence for concentration detection of normal and excited
atom in plasma [13, 27]. For the first time, the author reveals the availability of using
pulsed wavelength-tuned dye laser radiation [12, 36] for these purposes. The presence of coherent light source with gradually tuned wavelength during the recording
of resonance interferograms enables to approach to the absorption line of the components of heterogeneity arbitrary close that considerably increases the sensitivity of
this method to the definite type of particles [27, 37, 38]. As well as great sensitivity
increasing it also enables to study space distribution of the given component without
distorted influence of the rest of the components, so it becomes possible to determine
the contribution to the refraction of different components of the mixture. The method
sensitivity is considered, and the boundaries are determined of its applicability for
