The stationary localized solutions in the subcritical complex Ginzburg-Landau equation are studied. It was showed that pulses in the complete quintic one-dimensional Ginzburg-Landau equation with complex coefficients appear through a saddle-node bifurcation which is determined analytically through a suitable approximation of the explicit form of the pulses. The results are in excellent agreement with direct numerical simulations.
