| Abstract: | Abstract The results of theoretical and experimental investigations of the quasi-waveguide laser system with light-induced distributed feedback (DFB) are given. The DFB theory in the system is developed. The threshold and spectral angular characteristics of operation are calculated. Frequency-tuneable operation of the system in single-mode and multimode regimes have been investigated. |
