Spatial-spectral interference is an effective way to characterize an unknown ultra-short pulse. The key of characterizing an unknown ultra-short pulse is to retrieve the dispersion. Considering that the spatial-spectral interference fringe is the equiphase line of different spectra in the space domain and that the phase difference between adjacent interferences is equal to 2π, we propose a novel method of dispersion retrieval for spatial-spectral interference. The analytic expression is deduced and demonstrated by simulated experiments. This method has the advantages of intuitive principle, less calculation and simple process with no Fourier transform, which are beneficial for practical applications.

We propose and demonstrate an all-fiber laser generating cylindrical vector beams efficiently using a home-made ring-core Yb-doped fiber. In this fiber laser, annular doping and ring-type beam pump are realized simultaneously, which are beneficial for remarkably improving the efficiency of high-order mode. Thus this laser oscillates in high-order $\mathrm{LP}_{11}$ mode stably with a high slope efficiency of 54.3%.

Domestic and foreign scholars have carried out a lot of empirical studies on entrepreneur orientation, enterprise capability and innovation performance. However, the main concentration is on the technological innovation, rarely on the service innovation, which is the key element for sustainable development of manufacturing enterprises. Then, what's the relationship between these three constructs? Therefore, a relational model of these three factors, considering the moderating effect of environmental uncertainty. 193 large and medium-sized manufacturing enterprises in Northeast China were used as the sample to carry out an empirical study, which demonstrates: (1) The innovativeness and proactive of entrepreneur orientation have significant impact on service innovation performance; (2) There is positive correlation between capital capability, network capability, management capability and service innovation performance; (3) Environmental uncertainty is the moderator variable between entrepreneur orientation and enterprise capability and service innovation performance.

Appraising the present level of intellectual property right protection accurately is the important work for one country to design appropriate intellectual property right policy. The existing appraisal systems of intellectual property right protection have the problems of unreasonable index and appraisal method. This paper presents a comparative appraisal method based on expert evaluation. In this method, we appraise the level of intellectual property right protection through comparing it with one country's level of economy, science and technology development. But this comparative appraisal method is based on the subjective judge of experts, so there will be uncertainty in the appraisal course and results. In order to lest the subjectivity and uncertainty of experts' opinions and make the appraisal process and result more objective, the paper introduces the theory of evidence to synthesize the experts' opinions and studies the course of comparative appraisal of intellectual property right protection based on the theory of evidence.

We have developed the prototype facility of Shenguang III for the laser driven inertia confined fusion. The characteristics and recent progress of the facility was demonstrated. The facility using a new scheme of four-pass amplifiers, all-fiber front-end, compacted PEPC et al has provided primary target-shooting experimental operation and will provide crucial data for the design and construction of the Shenguang III laser fusion driver.

The method of the power spectrum density analysis is introduced, which had been used to evaluate the imperfect surface figure of optics, to analyze the spatial frequency distribution of near field at the condition of beam nonlinear propagation.
