In this paper, we investigate numerically steady-state behavior of a highly nonlinear photonic crystal fiber (PCF) Raman laser. The
threshold power proportional photonic crystal fiber length has been studied. As well as, two types of Raman fiber lasers (RFLs), with- and
without Bragg gratings have been compared. Calculations are performed using Runge-Kutta method. Transmission power and output power of
the 2nd-order Stokes radiation toward input pump power for low-reflectivity mirrors cascade Raman resonator have been presented. Moreover,
forward propagation of the 1st-order Stokes wave changes have been shown as indicator for satisfactory output power in the acceptable rang of
the PCF length. We explain trade-off between attenuation dependence of effective length and output power. Finally, output power versus
reflection- and transmission coefficients before fiber-end facet has been described.
