Summary
We show that in case of (1+1)-photon resonant absorption to and emission from an autoionizing state embedded into a continuum, the gain profile can be modified significantly in the presence of a parallel near-resonant channel leading to another autoionizing state embedded into a different continuum. Due to the coupling between two channels via cross-photoionization (i.e. ionization from the intermediate state of one channel to the continuum of another channel) the gain can be obtained around three different frequencies leading to lasing without population inversion. Results of parametric calculations are presented.
