Abstract
A compact external cavity fiber laser has been proposed by using a silver diaphragm as the end-coupled cavity of Distributed Bragg Reflector. In this paper, structure and performance of the optimized all-fiber laser with external cavity is in good agreement with the theoretical analysis and numerical simulation. Meanwhile, experimental results demonstrate that the external cavity laser based on Distributed Bragg Reflector fiber laser could reduce threshold pump power from 25.6mW to 24.0mW and narrow the linewidth from 28.3kHz to 16.4kHz.
