T. Rosadiuk et J. Conradi, OUTPUT COUPLING INDUCED WAVELENGTH SHIFTS IN ERBIUM-DOPED FIBER LASERS, IEEE photonics technology letters, 5(7), 1993, pp. 758-760
We present experimental results of shifting the operating wavelength o
f erbium fiber lasers by varying the wavelength independent output cou
pling. No wavelength selective elements are incorporated in the laser
cavity. The results are in agreement with a simplified theory as previ
ously published by others.
