The coupled-wave approach was used for the analysis of volume gratings in a medium with light gain for the sake of oscillation threshold determination in the second-order Bragg diffraction regime. The conditions for self-starting oscillations were analytically determined and found to be optimal for mixed phase-amplitude gratings. The properties of a distributed-feedback laser scheme are derived on the basis of the obtained results.
