COHERENT LIGHT-RECORDING TECHNIQUES( Book )

3 editions published between 1964 and 1965 in English and held by 3 WorldCat member libraries worldwide

The purpose of this report is to summarize, define and demonstrate techniques necessary for the application of coherent light to the problems of recording and readout of analog information in excess of 10 to the 10th power bits per square inch, at frequency bandwidths of 100 megacycles per second. Investigations into such areas as the coherent light source itself, modulation, deflection or scanning techniques, readout techniques and the evaluation of recording media are reported

Fluorine Spin Diffusion Barrier in Pr3+:LaF3 Observed by Cross Relaxation( Book )

1 edition published in 1992 in English and held by 1 WorldCat member library worldwide

Photon echo measurements made at 2 OK on the 3H4 - ID2 transition in pr3+:LaF3 show that magnetic dipolar couplings between the Pr and F nuclei account for the 56 kHz homogeneous linewidth of this transition. The homogeneous broadening arises from the enhanced 141 Pr nuclear moment (I=5/2) interacting with the local field fluctuations of the 19 F nuclear moments undergoing mutual spin flip transitions. Such resonant fluctuations should, in the absence of a fluorine spin diffusion barrier, produce a homogeneous linewidth of about 200 kHz which is, in fact, roughly what is observed for the inhomogeneous broadening of the Pr3+ hyperfine levels and is considerably broader than that obtained by the photon echo measurements. Shelby et al 2 proposed a simple model analogous to the spin diffusion barriers responsible for narrowing the homogeneous lines in certain electron paramagnetic resonance transitions. In such systems, the field produced by the electron magnetic dipole moment (orders of magnitude larger than the enhanced nuclear moment associated with the ground state of Pr3+ in LaF3) de-tunes the nearest neighbors from each other, prohibiting mutual spin flips among them. Thus, the Fields produced by the neighboring spins are static and their interaction with the paramagnetic ion contributes to the inhomogeneous linewidth and not to homogeneous broadening

Longitudinal nuclear spin-spin relaxation( Book )

1 edition published in 1963 in English and held by 1 WorldCat member library worldwide

A theoretical and experimental study is made of the nuclear magnetization which appears after a sudden unidirectional step magnetic field is applied non-adiabatically to an ordered spin system prepared by the process of adiabatic demagnetization. The magnetization exhibits damped oscillation about a non-vanishing equilibrium value. The oscillation frequencies correspond to the fundamental and harmonic components of Larmor frequency. The oscillations arise as the internally ordered dipole-dipole interaction energy exchanges with the suddenly imposed Zeeman energy reservoir. A density matrix calculation carried to second order in time dependent perturbation theory, combined with a gaussian decay model, accounts for the observed oscillations within times comparable to the decay time. Fluorine nuclei in single CaF2 crystals are studied for various crystal orientations with respect to the applied step field. (Author)

Optical Pumping Detection of Anomalous NQR Spectra of Pr3+ in Pr3+:LaF3( Book )

1 edition published in 1992 in English and held by 1 WorldCat member library worldwide

The nature of inhomogeneous broadening in rare earth systems plays an important role in the dynamical optical -properties of ions in crystals. For this reason much of the work on the nature of the inhomogeneous broadening in rare earth doped systems has concentrated on the investigation of ion-ion interactions such as spectral transfer and up conversion processes. Variations in homogeneous optical dephasing times across the inhomogeneous optical line have also been reported. These studies concentrate on the variations of collective effects of ion- ion interactions at different positions in the inhomogeneous optical line in relatively heavily doped rare earth systems. We report variations in optically detected NQR (ODNQR) linewidths and shifts of Pr3+ hyperfine transitions in the optical ground state as a function of position in the inhomogeneous optical line and for satellite transitions of the 1D2-3H4 transition in lightly doped (0.5 at.%) Pr3+:LaF3. A systematic increase in the broadening of the Pr hyperfine transitions is observed as the laser is tuned toward the wings of the inhomogeneous optical transition without a shift of the NQR center frequency. The principle contribution to the 200KHz (FWHM) inhomogeneous width of the Pr hyperfine levels is explained by magnetic dipole-dipole interactions between the Pr nuclei and the neighboring fluorine spins. This contribution remains constant across the Stark broadened optical transition. Thus we show the existence of an additional broadening mechanism
