The stationary, localized solutions in the complex subcritical Ginzburg-Landau equation in the region, where there existed coexistence of homogeneous attractors, were discussed. The asymptotical value of the phase gradient and the sizes of stable pulse were also determined. The appearance of pulses were found to be related to a saddle-node bifurcation.
