Spatial coherence and coherent interactions of broadband dispersed laser beams

Isotope shifts inNe20,22: Precision measurements and global analysis in the framework of intermediate coupling

“…Except for the core shift, and excluding higher order terms, all np levels are expected to have the same SMS, since no G 1 Slater integral appears in the energy difference between terms [66]. The fact that np levels do not have the same RIS was first evident in the measurements of [81] but overlooked later in the analysis of [58,82]. Since the LS-dependent relativistic corrections which appear in [79,83], are estimated to be much smaller, this difference has been attributed to the CSO effect of the SMS and electrostatic energy operators [75].…”

Measurement of the ${}^{\mathrm{20,22}}$Ne ${}^{3}{{\rm{P}}}_{2}{{\rm{\mbox{--}}}}^{3}{{\rm{D}}}_{3}$ transition isotope shift using a single, phase-modulated laser beam

“…Figure 7 and table 1 shows a comparison between the results presented here, and those of other groups using various experimental techniques. We note that earlier attempts [25][26][27][28][29], obtained a 4 MHz larger shift than those more recent and accurate, that is, measurements presented in this work and in [24]. It would thus be beneficial to conduct a high accuracy, ab initio calculation of this quantity, which as far as we know, does not exist in the literature [24].…”

“…By measuring 21 Ne as well, it is also possible to improve determination of the -20 22 Ne charge radii difference [32]. [26]; (e) Basar et al [27]; (f) Odintsov et al [28]; and (g) Konz et al [29]. 1625.9±0.15…”

Statistical characteristics of spatial fluctuations in intensity of dispersed laser beams

“…However, for the creation of efficient schemes of the fourwave interaction and coherent wavefront reversal [2] of radiation of broadband lasers, it is necessary to know how the dispersion influences the characteristics of the laser beams. The spatial coherence of dispersed beams has been studied in [3,4], and the existence of its spatial fluctuations was ascertained. In the present paper, spatial fluctuations of the intensity (speckle structure) of dispersed beams are studied and the dependence of the fluctuations on the longitudinal coordinate z is found.…”
