Characterization of Er3+ 2.79μm rotating mirror Q-switched laser

Abstract

Abstract: 2.7-3μm laser, which has the important value of medical and military applications, are obtained from the transition 4I11/2 →4I13/2 with rare earth Er3+ as the active ions and YSGG, GGG, GSGG, YAG, YLF as the matrix material. Under the effect of 790nm pump light, the Er:YSGG as laser material can produce 2.79μm stimulated emission. By building the rate equation of Er:YSGG energy level transition, we analyze the system characteristics of rotating mirror Q-switched laser and do some numerical simulations. Result of the numerical simulations can help us obtain the the influence of system variables on the performance of rotating mirror Q-switched laser. These conclusion will provide theoretical guidance for the design and improvement of similar experiment.
