The study results indicate that as emission power increases, the peak power density on the section of a certain distance will increase firstly, then it will descend and that the peak light intensity on the section will increase with the increasing of spot radius of basic mode Gaussian beam. As the propagation distance increases, the peak light intensity on the section will descend gradually, and the laser energy will spread. The light intensity distribution exhibits straw hat shape on a certain conditions, in other word to say, the central light intensity is less than acroteric light intensity.

The characters of powder are connected with the inside structure and synthesize-technics of materials. In this paper, we want to search a optimize technics of materials synthesizing, and prepare a kind of nanosize powder which shape like ball and have good dispersed character. At the same time, we want to obtain a bridge structure of Zn-O-Tb through dopping of Tb, which can achieve efficient energy transfer from ZnO hosts to excited states of dopants, The doped powder can eradiate blazing green light because of efficient emission buildup from dopants and ZnO hosts, and the powder can emission a pure light. And we want to research the structure in doped ZnO for the further research of low-tension fluorescence of ZnO.

The emission of N_2 in discharge gap is detected using optical emission spectrophy. The discharge reactor was put in lightproof box to avoid the disturbance from outside lights. A small hole was drilled in one sidewall of the box, and the fibre was mounted coupling to the inlet (1mm) into the hole. A tube with the inner diameter of 1.1mm was set in the front of the hole. In this way, only the light from a certain direction emitted from the discharge reactor could transfer into the inlet through the tube. The reactor could be moved in the vertical direction of the fibre, and the spectrometry can collect the total emission along the fibre inlet in single-shot measurement.
