Abstract
At least some rare earth-doped optical fiber lasers are subject to self-pulsing and/or relatively high noise. We have found that these shortcomings can be eliminated if the cavity length of the fiber laser is increased, typically by inclusion of a length .LAMBDA. of rare earth-free conventional (single mode) transmission fiber in the cavity, with .LAMBDA.>0.3L, where L is the effective cavity length of the laser.
