Abstract

Abstract

This paper reports a new type ofhigh density side injection waveguide laser. The surrounded high-density side injection technology and the specially processed bare gain fiber are applied. When the injected pump power is 320 W, the highest continuous output power 28 W is obtained with the slope efficiency of 20% and the central wavelength is of 1080 nm, which shows that the structure of surrounded side injection is feasible. There is still much room for development of output power and slope efficiency of the novel laser in the future.
