  We show that an absolute coherent phase of a laser can be used to manipulate
the entanglement of photon pairs of two-photon laser. Our focus is on the
generation of a continuous source of entangled photon pairs in the double
$\Lambda $ (or Raman) scheme. We study the dependence of steady state
entanglement on the phase and laser parameters. We obtain a relationship
between entanglement and two-photon correlation. We derive conditions that give
steady state entanglement for the Raman-EIT scheme and use it to identify
region of steady state macroscopic entanglement. No entanglement is found for
the double resonant Raman scheme for any laser parameters.
