The authors present for the first time DBR-emission in an electrically pumped CdZnSe/ZnSSe/MgZnSSe laser at room temperature. Longitudinal single mode emission is observed. By changing the period of the Bragg reflector, the emission peak can be tuned over >40 meV. The threshold current strongly depends on the reflector period with a minimum value of ~160 mA.
