Abstract

In order that numerical simulation of the bidirectional pumped,erbium and ytterbium co-doped phosphate glass waveguide laser fabricated by femtosecond laser pulses was performed,based on the transition rate equations and propagation equations of the erbium and ytterbium co-doped system,the optimal parameters such as the size of the waveguide,output coupler reflectivity,the ratio of Er3+/Yb3+ were obtained.The results indicated that with the parameters of 10mm long waveguide,0.6 of the mirror reflectivity and 3.6 of the ratio of Er3+/Yb3+,the laser at 1535nm output up to 57mW with the pump power of 400mW at 975nm.The theoretical analysis agreed well with the experimental results reported so far.The simulation results provide a rigid theoretical Ease for the fabrication of active glass waveguide and the design of femtosecond laser.
