Paper Abstract

Threshold and polarization characteristics as well as temperature dependence of a two-band generation of laser with distributed feedback based on induced cholesterical liquid crystals (CLC) were studied. Difference between threshold excitation intensities of these bands of generation points at the existence of two phase gratings in the helical structure of CLC. It is verified by the difference in the temperature behavior of the wavelengths of the central lines of the bands.
