In this paper we have presented characteristics of MBE ZnCdSe/ZnSe superlattice structures (SLSs). The e-beam pumped VCSELs on the basis of the structures  operating at room temperature in a blue-green range were fabricated. The Stokes shift and appearance of new lines in CL and phototransmission spectra with increasing SLSs thickness have been observed. Nevertheless, the best SL structures had a small enough QW radiation line width (16 meV at 40 K). The single longitudinal mode lasing with  the peak output power to be 2.2 W at 493 nm has been observed. The cut facet laser wavelength was found to be greater than the laser wavelength of the VCSEL by 40 meV. The possibilities of a low threshold current operation of the LCRT based on the MBE grown SLS was demonstrated in this work.
