    • Abstract

       

      We have described here the physical basis for lasing without population inversion (LWOPI). This type of amplification is obtained basically by two mechanisms: (i) one is based on atomic interference and (ii) the other is based on Fano-type interference. We have shown here, in H2 molecules, amplification without population inversion is feasible by considering both the mechanisms.
