M. Duelli,G. Montemezzani,M. Zgonik,P. Günteroses (Clutton-Brock, 1981): for about 4,000 years he has also kept wild animals in captivity as symbols of power, prestige and amusement. These early menageries usually served for entertainment, although a few such as that of the Chou dynasty were arranged as educational and cultural displays. All winspiration 发表于 2025-3-23 18:39:56

The Photorefractive Effect in Inorganic and Organic Materials,tion from (thermal) equilibrium . Examples of material excitations are an increase in the number of conducting free electrons, the phonon density or the number of electrons occupying excited states. As a result of spatially inhomogeneous material excitation, the optical properties become spatiaBarrister 发表于 2025-3-24 21:58:05
Photorefractive Memories for Optical Processing,unities. Volume holographic storage was proposed by van Heerden shortly after the introduction of the laser and interest in this technology has continued at varying degrees of intensity since. Holography potentially combines the advantages of high storage densities and ease of parallel data re性上瘾 发表于 2025-3-25 01:12:35
Second-Harmonic Generation in Ferroelectric Waveguides,e been aimed at the realization of compact all-solid state blue lasers based on near-infrared diode lasers, e.g. AlGaAs and InGaAs diode lasers, and of diode-pumped solid state lasers, e.g. Nd:YAG lasers, frequency doubled in a nonlinear waveguide. Waveguides provide ideal structures for efficient f
