Design and optimization of a diode-pumped fiber-coupled Yb : Er glass waveguide laser

An adaptive simulated annealing optimization algorithm is used to derive la ser rate equation and waveguiding models with which the best design for a d iode-pumped fiber-coupled, Yb:Er glass waveguide laser can be determined. M aterial parameters that correspond to commercially available laser-glass an d diode-pump sources are used in this study. Given a continuous-wave 300-mW pump at 977 nm, approximately 48 mW of power at 1540 nn can be coupled int o the LP01 mode of an optical fiber. Fabrication and alignment tolerance an alyses are presented. (C) 2000 Optical Society of America OCIS codes: 140.3 500, 130.3120, 220.4830, 136.2790, 140.5680.
