A mode-locked erbium-ytterbium fiber laser operating at 1550 nm using multiple quantum well (MQW) saturable absorbers was developed. The laser was constructed in a Fabry-Perot configuration using a fiber Bragg grating as a front reflector and a fiber chirped Bragg grating output as a back reflector of the laser cavity. The laser can either produce Q-switched or CW passively mode-locked pulse trains by simply changing the location of the saturable absorber with respect to a focal plane. The pulse train of laser Q- switching operates at an 85-KHz repetition rate when the position of the absorber is near the focus. Peak power of the Q-switching pulses is about thirty times higher than for the CW mode locking which occurs when the absorber is placed exactly at the focal plane. The CW passively mode-locked pulse trains have a 19-MHz repetition rate with 2.6-mW average output power.
