**4. Conclusion**

As seen, the laser emission is observed from all the area of the pumping where the peaks of emission are allocated as microlaser stripes. Naturally, the peaks of lasing of these strips correspond to the intensity maximums of the interference pattern formed by the pumping

In **Figure 14**, the laser emission spectrum is shown. The spectrum along the cross section of the lasing of the radiation is strongly constant. The obtained spectrum of lasing is caused by the dye concentration, polymer matrix properties, and spectral reflection characteristics of the

This work shows the possibility of creation of laser active holographic structures controlled by the transversely distributed optical pumping in dye-doped CLC and polymer layers. The obtained results confirm mutually coherency of the microlasers forming with the help of transversely distributed pumping. So laser radiation of such structures carries information about the spatial modulation of the pumping light field. Therefore laser active holographic structures resemble to corresponding usual holographic structures, but they are reconstructing information with the help of own laser radiation but not by diffraction of incident light. On author's opinion, similar structures will reconstruct object images analogically to usual holograms and will create a basis for the development of new direction of optical information technologies.
