Abstract
New construction of a silica-based multi-ring profile of Tm3+ doped fiber laser is presented. Optimisation of both multi-ring refractive index profile and active ions distribution towards high beam quality mode propagation is a new approach in developing active fiber constructions. Using a system of layers forming the core allows controlling the dopant profile and, consequently, the emission properties of fiber lasers (power density, beam profile shape etc.). The preform fabricated using MCVD technology is presented. The refractive index profile (Delta n = 9.10(-3)), EPMA-EDS analysis (Tm2O3 and Al2O3 concentration 0.56 and 5.2 wt% respectively), and excited state (F-3(4)) decay time are shown. The double-clad fiber laser based on the Fabry-Perot resonator construction (17/240 mu m core/cladding) was used for single-mode laser beam generation at a wavelength of 1938.8 nm (exc. @ 790 nm) with an FWHM bandwidth of 0.17 nm (1.68 W output power, M-x(2) = 1.10, M-y(2) = 1.23). For the optimized gain fiber (25/330 mu m core/cladding diameters) length, the laser provided an output power of >5 W with a slope efficiency of similar to 26%, determined to the absorbed pump power.
