Abstract
We present experimental results of a proposed dual wavelength fiber laser with Er/Yb double clad fiber. The linear cavity laser is based in the use of two fiber Bragg gratings for wavelength selection and a Sagnac interferometer for cavity losses adjustment to obtain dual-wavelength operation. With pump power variations from the lasing threshold to 890 mW. Self-Q-switched pulses are obtained. With a pump power range from 1.1 W to 1.7 W, self-pulsing operation is observed. With pump power above 2 W CW operation is achieved.
