The stability of the homogeneously broadened and degenerate two-photon running wave laser is analysed by using the full set of matter-field equations. The stability depends on the relative size of the relaxation constants. For 2 k>1+r(k=κ/γ, r=γ; κ is the cavity loss of the field and γ are the longitudinal and transversal decay constants, respectively) no stable lasing state exists. For r<k<(1+r)/2 an instability occurs. With the decrease in pumping the stable lasing state loses its stability due to Hopf-bifurcation.
