Paper Abstract

Scalar finite-element-method optimization algorithm was used to calculate the effective index and mode field distribution in a LD-pumped SMF-coupled Er:Yb co-doped glass channel waveguide lasers. The channel waveguides were made by electric field assisted K+-Na+ ion-exchanged in commercially available laser glass, and it supports a single mode at 1540-nm laser wavelength and double mode at 980 nm pump wavelength. Applied the optimized parameters, we designed the waveguide lasers which can convert 200 mW continuous-wave power at 980-nm from a LD-pump laser into 18 mW of continuous-wave at 1540-nm coupled into the LPO1 mode of standard single-mode fiber.
