In this work the approach to designing and manufacturing  the mirrors for optical cavities of the lasers with simultaneous generation at two different transitions is formulated. Using the model of equivalent layer, the structures of the mirrors for He-Ne lasers operating at the wavelengths of l0=0.6328 mkm  and l1=3.39 mkm are described. The efficiency of use of the obtained mirrors in serial lasers is demonstrated.
