It is performed the theoretical investigation of lasing of undulator FEL with volume distributed feedback (VDFB) which was firstly proposed in [1-3]. The volume distributed feedback results in the essential modification of the beam instability. The conditions when new generation laws become apparent in the volume diffraction geometry are defined.
