Single-frequency distributed feedback (DFB) and distributed Bragg reflector (DBR) Er3+-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, limiting laser output powers to < 1mW. Higher laser output powers are clearly desirable, e.g., for CATV applications. Previous ways suggested for dealing with this issue include redirecting the unabsorbed pump-to-power fiber amplifier, intracavity pumping, or increasing the 980-nm absorption with co-doped Yb3+:Er3+ phosphosilicate fibers.
