The tensor properties of χ(2) gratings written in bulk glass have been studied for various polarization conditions. Three basic cases were studied: the writing of gratings by waves with parallel polarizations, perpendicular polarizations, and polari

Picosecond pulses of neodymium laser radiation and its second harmonic were used in recording of holograms. These holograms exhibited an angular selectivity. Coherent erasure of holograms by second exposure to signals with the opposite sign of the ph

Induced second-harmonic generation has been observed in a number of colored glasses with high lead content, at efficiencies that are an order of magnitude higher on the average than in germanium silicate preforms for optical fibers. This highest coef

A theoretical investigation is made of the influence of linear amplification as a result of stimulated Brillouin scattering in a multimode fiber waveguide. Calculations are made of the threshold of such scattering and of the efficiency of conversion

An experimental investigation was made of stimulated Brillouin scattering (STBS) in Nd3+–activated glass fibers. Optical pumping of these fibers at the wavelength of 1.06 μ resulted in amplification. Linear amplification in these fibers lowered th
