Experimental study and numerical modeling of a cw-pumped all-solid- state fiber erbium laser passively Q-switched with a Co2+:ZnSe crystal is proceeded for the first time to our knowledge. Features of the laser dynamics are investigated from a super-luminescence regime via passive Q-switching mode to cw operation. The basical parameters of the passive Q-switching mode - giant pulses’ repetition rate, duration, and energy - are calculated numerically and measured experimentally. Experimental results are shown to be in quite-well agreement with a simple theoretical model of the laser.
