摘要：
An all-fiber passively Q-switched erbium/ytterbium co-doped cladding pumped fiber laser is presented. A section of erbium/ytterbium co-doped fiber is used as both gain medium and saturable absorber, which makes the laser configuration simple and compact. By properly choosing the splitting ratio of the laser output coupler, stable Q-switching could be achieved. It has been found that the splitting ratio of the output coupler is very important for generating stable Q-switching pulses. The operation range of stable Q-switching is different for different lengths of the erbium/ytterbium co-doped fiber. Self-mode-locking effect is also observed accompanying with the Q-switched pulses. The characteristics of the laser output against the pump power and the splitting ratio of the output coupler are studied in detail.
