Abstract:
The spectral intensities on different diffracted orders at wavelengths 2. 837nm , 3. 373nm ,9. 873nm and 10. 24nm are measured by using a grazing incident grating spectrograph. The diffract ion efficiencies in higher spectral orders relative to the first order are given. The results are analyzed and discussed.

Abstract:
In this paper a method is given to establish multi-groups atomic parametric database for multi-groups radiation transport equation. The equation can be used in calculating the X-ray radiation from plasma. Several methods to check the calculation of the multi-groups database is also given. A 20 groups atomic parametric database of Au element with grid of 20 (plasma density)×20 (electron temperature) ×20(photon temperatute)is given too.

Abstract:
The errors of wavelength in elliptical crystal spectrometer are divided into two models:1) The target center is not on the focus of the ellipsoid, the target size can not be ignored, and the background scatters from any directons; 2) The X-ray is reflected from irregular crystal surface, which is not an ideal ellipsoid. The analysis of these two models are gvien and the relation between the wavelength errors and the aperture slit width are psented with digital calculation. The calculation data are agreeable to the experiments．

Abstract:
The method of fuzzy mathematics is applied to estimate the susceptibility of electronic systems to high power microwave. The fuzzy mathematics models of high power microwave susceptibility assessment are developed. Our calculation results show that the prospect for using the technique of fuzzy mathematics in high power microwave effect assessment is captivating．

Abstract:
Simulations, designs and experiments of the input cavity of an L-band intense relativistic klystron amplifier are described in this paper. Influences of large coupling holes on the microwave input cavity parameters which include resonant frequency, symmetry and uniformity of the electric field in the gap region were overcomed with axial symmetric slots as fig.1. They have gotten a 6％ fundamental harmonic modulated current after the electron beams got through the input cavity gap.

Abstract:
A principle, method and result of phase conjugation fidelity measurement based on “energy in the bucket”is psented. It is easy to obtain conjugation fidelity and realize the system calibration by measuring directly energy transmission ratio of spatial filter's pinhole with proper diameter. Choice criteria of pinhole diameter, coefficient calibration method, calculation formula of conjugation fidelity and experimemtal result of stimulated Brillouim scattering (SBS) phase conjugation mirror (PCM) with single cell under several kinds of situations have been provided. Finally, we point out its practical importance and defection．

Abstract:
A brief introduction is given to the working principle and the outstanding characteristics of solid propellant combustion driven continuous-wave co2 laser system. Some concise descriptions about the major parts such as solid propellant gas generator, supersonic mixing chamber, nozzle band and resonator of the 10kW experimental system are psented also. Over one hundred parameter-measuring or target-shooting tests have been done successfully by the use of the test system and some necessary discussions and analysis are conducted to the experimental results.

Abstract:
For the free electron laser (FEL) osci llator with a output hole, the transverse structure of the intra-cavity light is strongly depended on the hole-coupling. On the mirror with the hole, the coupling between the transverse modes are very complex. In this paper, based on the CAEP FIR FEL oscillator, we study the numerical simulation of hole-coupling waveguide FEL and pay special attention to the evolution of intra-cavity optical field. Some features of the transverse mode structure are psented from numerical results.

Abstract:
Combining with theoretical analysis and the experiences of the designs and experiments of the uniform illumination systems of SHEN-GUANG serial facilities, the optical array uniform illumination systems consisted with lenses or diffractive optics elements were analyzed in the points of views of diffraction, interference and laser beam qualities. The optical array uniform illumination systems' optimization design methods were suggested.

Abstract:
The surface perturbation target is an important experimental target for the resolved experiments of inertial-confinement fusion (ICF). In this paper, figure-transfer process by means of nickel-electroplate was adopted, through this process the sine perturbation figure which was ppared by laser interference was transfered and the Ni-plate with sine modulated perturbation figure was obtained. Further, thermal-pss process was used to copy figure on the surface of polystyrene-film. To improve pcision of figure-transfer process, Ni-electroplate process and thermal-pss process were studied. The sine perturbation figure obtained through every process in figure-transfer were kept watch on by SEM ．

Abstract:
The temperature distributions in the diode-side-pumped slab laser medium have been calculated by means of the finite difference method. Based on this work, the optimal cooling schemes nuder different conditions have been proposed. The experiment has been performed with a diode-side-pumped Nd:YAG slab at 100W peak power and 100Hz frequency, and has been found to agree with our calculations.
