Abstract :
In summary, Yb-doped clad-pumped fiber laser with a novel cavity was experimentally demonstrated where two concatenated tapers and the fiber Bragg grating with a sharp bandwidth of 0.2 nm made a highly efficient fiber laser. The efficiently packaged cavity showed a low insertion loss of 2.4 dB.
