Abstract
The affecting factors of 2 μm Tm3+-doped fiber laser output characteristics were theoretical analyzed. On the basis of the energy level structure and optical absorption properties of Tm3+ ion, combining with the basic principle of Tm3+-doped fiber laser, and starting from the energy level structures and the cross relaxation processes of Tm3+ ion, the three pumping methods of Tm doped fiber laser (TDF) were analyzed and discussed. The influences of output characteristics by different influence factors were simulated. Based on optimization of the equations, for different fiber lengths, doping concentrations and pumping absorption coefficients and other influence factors, the laser output characteristics under different conditions were obtained and analyzed. Combination the simulation analysis, through the reasonable design and the selection of the optimum parameters of the laser system, the high laser output performance scan be achieved by improving the injection power and controlling of fiber coil diameter. The influences of different factors on the output characteristics were analyzed in the issue. The high laser output performances can be obtained and the laser loss was reduced by selecting the parameters of the laser system properly.
