Phonon Dispersion Curves in Bismuth
Dispersion curves for phonons propagating in the trigonal direction in bismuth at room temperature and at 75°K have been obtained in a neutron inelastic scattering experiment. Expand

Observation of Solitons in Stimulated Raman Scattering
Anomalous pump-depletion reversal in stimulated Raman scattering has been observed and is interpreted as the development of a soliton induced by a random phase shift in the injected Stokes beam. TheExpand

Rapid recording of infrared spectra from pulsed chemical lasers
A method is described for rapidly recording permanent ir spectrograms of the output of a pulsed chemical laser. The method also lends itself to the simultaneous observation of the time behavior ofExpand

Neutron Diffraction Study of Ice Polymorphs under Helium Pressure
Neutron diffraction studies of several of the D2O ice polymorphs were made with helium pressures to 3.5 kbar. Volume compressions (ΔV / V) were obtained for ices Ih, Ic, and IX at 2.1 to 2.8 kbar.Expand

Oscillations of Gaussian beam parameters in periodic lens waveguides (A)
Abstract Gaussian beams propagating through periodic thin-lens waveguides are found to oscillate in Rayleigh range and waist longitudinal position. A differential expansion of expressions derivedExpand

Stimulated rotational Raman scattering in CO 2 -pumped para-H 2
Stimulated rotational Raman scattering in a 300 K multipass cell filled with para-H 2 with a single-mode CO 2 pump laser was studied using a single-mode OPO as a probe laser at the Stokes frequencyExpand
