This letter reports the results of thermal fixing of holographic grating in BaTiO 3 crystal, predicating the critical temperature of the formation of complementary ionic grating, the relation between the speed of ionic grating formation and temperature, the relation between the ionic grating formation and the diffractive light oscillation and the effect of different cooling ways on the efficiency of thermal fixing. Thermal fixing of holographic grating with high efficiency is also achieved. We have also observed some new interesting feature of erasing in high temperture and present explanations of the experimental results..

The identification of the chaotic optical system with BP feedforward neural network supported by a modified BP algorithm is suggested. The feasibility of this suggestion was demonstrated with computer simulation of the identification of the Bragg acoustooptic bistable & chaotic system. The computer simulation result shows that, the three layers foreward neural network, if trained with the chaos speedup BP algorithm, is indeed a fine identifier with less training iterations than usual. Thus it could be used to reconstruct the dynamics of the chaotic optical system with its output time series very efficiently..

Under free runing regime, we studied the influences of the reflection coefficients of the couple output mirror, the gasses pressure of the pump lamp, and the total capacitance of a storage bank on the output energy.

The angles of reflection and transmission from interaction of electromagnetic waves with a relativistic underdense ionization front are investgated. First, according to a phase matching condition of electromagnetic wave on the stationary boundary surface, we find the refelection and transimission angles in the front system with a static ionization front. Then using the transformations of wave vector and frequency we get the corresponding angles in the laboratory system in which the ionization front is moving at relativistic speed. The obtained results are discussed..

The photochromic property and colloidal formation mechanism of the sodium chloride crystal material colored by γ ray irradiation and electron beam bombardment are investigated systematically. The F→C conversion can be created efficiently by irradiating the colored crystals with a few laser pulses at 448 K. The sizes of the produced colloids augment with the increase of the colored doses. A new colloid whose absorption band located at 625 nm is produced and observed for the first time in the colored sodium chloride crystal. The C→F conversion can be carried out efficiently at 532 K, so the reversible conversion from F center to C center is realized. The F→C conversion is realized mainly by means of the agglomerating of mobile defects produced by the photoionization of F and F' centers under the F band laser irradiation. The brief physical interpretation is given on the colloidal formation mechanism..

The optimization for fabricating large cross section Si/GeSi/Si single mode rib waveguides with RF heated CVD method is discussed. The optimal fraction x of Ge in GeSi layer defined by the necessity of single mode, numerical aperture and critical thickness is between 1~3%. The height and width of rib must be also limited by the single mode and large cross section, The etched rib side walls are slope due to the Si crystal structure. The best initial width of rib is 5~6 μm. The etching and polishing solutions must ensure the rib side walls and end faces to be mirror. The measured results show that the performance of the optical waveguides improred remarkably. The output light field is increased and the propagation losses is less than 0.5 dB/cm..

We study the statistics of scintillation at the airborne receiver for space earth space link by analysed the modulatory mechanism of atmospheric turbulence and terrain scattering on propagating laser beam. The scintillational statistics are governed by the joine effects of atmospheric turbulence and terrain scattering (such as terrain, sea and forest). The probability density functions of scintillation for the terrain, the sea surface and the forest, the two scattering terrain model was obtained, in which the probability integral is made by the method of steepest descent. The joine distribution of geneval Chi-Squared distribution for scattering terrain and atmospheric turbulance is found flatten markedly and its peak shifts to the low end of normalized irradiance..

Properties of an optical quality circular metallic hollow waveguide are discussed and the technique for fabricating such a waveguide is decribed. The waveguide with gold or silver as the waveguide cladding material exhibits the characteristics of low propagation loss, transmission insensative to waveguide bending and misalignment, and capability of transmitting high power light from visible to far infrared. It is demonstrated that transmission of He Ne laser is independent of the refractive index of the liquid filled into a gold hollow waveguide, and this characteristic greatly extends the nonlinear waveguide applications. The mechanism for a “hollow fiber” in the 10.6 μm spectral region is discussed and results of propagation of CO2 laser through a gold hollow waveguide are presented..

Zeeman modulation magnetic rotation laser spectroscopy (ZM-MRS) was first used to seperate the magneticc rotation signal (n +-n -) effectively from the laser background and the high order terms of magnetic rotation signal in visible region. It not only has very high sensitivity, high signal to noise ration and no absorption background and also can suppress the rotational spectrum with high quantum number for simplifying complex electronic spectra. In this paper the theoretical analysis of this technique is simulated by computer. The results are fitted well with the experiment. This spectrscopic method is valuable for measuring free radicals and helpful for assignment of molecular spectrum..
