Experimental research on discharge characteristics and laser pump performance of electrodeless micro xenon lamp

Abstract

In this paper, a kind of electrodeless millimeter diameter micro xenon lamp was developed. The micro xenon lamp was driven by inductive coupling. The experimental investigation of the discharge characteristics and laser pump performance of the developed micro xenon lamp have been carried out. The energy coupling efficiency of the drive scheme is between 22.4% and 24.2%. The fluorescent spectrum of micro xenon lamp is composed of line spectrum and continuous spectrum, which is well matched with Nd3+ absorption spectrum. Because of its small size and flexible layout, it is suitable to be used as the pump light source of fiber laser. The fluorescence radiation of fiber can be improved by using multiple micro xenon lamps. Four micro xenon lamps can improve the fluorescence radiation power by 80.5% compared with only one.The results indicate a complete set of micro xenon lamps can be applied in the field of fiber lasers.
