Continuous-wave operation of Tm3+ doped fluorozirconate fiber laser, simultaneously at around 1.9m and 2.3m when pumped at around 790nm, is theoretically modeled. The model based on the formalism of the rate equation predicts that Excited-state absorption (ESA) at the pumping wavelength cant affect the dynamical behavior of our laser .
