Efficient operation and characterization of distributed feedback Er/sup 3+/-doped fiber lasers via the 520-nm transition band

Single-frequency distributed feedback (DFB) and distributed Bragg reflector (DBR) Er/sup 3+/-fiber lasers are attractive for applications in optical communications and sensor systems. However, as the cavity lengths need to be short (a few cm) for robust single-mode operation, pump absorption is low,...
