In this paper, we review the status of the multifunctional experimental platform at the National Laboratory of High Power Laser and Physics (NLHPLP). The platform, including the SG-II laser facility, SG-II 9th beam, SG-II upgrade (SG-II UP) facility, and SG-II 5 PW facility, is operational and available for interested scientists studying inertial confinement fusion (ICF) and a broad range of high-energy-density physics. These facilities can provide important experimental capabilities by combining different pulse widths of nanosecond, picosecond, and femtosecond scales. In addition, the SG-II UP facility, consisting of a single petawatt system and an eight-beam nanosecond system, is introduced including several laser technologies that have been developed to ensure the performance of the facility. Recent developments of the SG-II 5 PW facility are also presented.
Although emotional labor in the workplace has been of increasing interest to researchers, the complete process of emotional labor has seldom been systematically analyzed. This paper explores the links between emotional job demand and its psychological effects on employees, with a particular focus on the mediation of emotional labor strategies and the moderation of social support. The results of a survey of 679 Chinese employees in the service sector reveal that emotional job demand significantly increases emotional exhaustion and reduces job satisfaction. Two emotional labor strategies, surface acting and deep acting, partially mediate these associations. Social support significantly moderates the relationships between deep acting and emotional job demand and its psychological effects, but does not do so for surface acting. Suggestions are offered accordingly for organizations wishing to reduce the negative influence of emotional labor on employees and improve the efficiency of service enterprises.
Beam positioning stability in a laser-driven inertial confinement fusion (ICF) facility is a vital problem that needs to be fixed. Each laser beam in the facility is transmitted in lots of optics for hundreds of meters, and then targeted in a micro-sized pellet to realize controllable fusion. Any turbulence in the environment in such long-distance propagation would affect the displacement of optics and further result in beam focusing and positioning errors. This study concluded that the errors on each of the optics contributed to the target, and it presents an efficient method of enhancing the beam stability by eliminating errors on error-sensitive optics. Optimizations of the optical system and mechanical supporting structures are also presented.
