Abstract :
In this paper, we present a model describing the time dependent characteristics of a passive Q-switching (PQS) laser composed of amplifying and saturable absorber fibers, specially taking into account the transverse singlemode intensity distribution, long interaction length, high gain and absorption coefficients, and including the effects of amplified spontaneous emission
