Abstract
A Λ-type inversionless laser scheme is analyzed in which lasing is achieved under conditions when a conventional or a Raman laser would fail to operate. The dependence of gain on the parameters of the system is studied numerically. A realization in heliumlike ions is proposed which permits laser action at a wavelength of around 6 nm.
