Distributed feedback in lasers with nonstationary pumping; possibility of resonatorless generation in the ultraviolet
Akhmanov S.A., Lyakhov G.A.
We consider certain new applications of distributed feedback (DFB) due to spatial modulation of the gain in laser systems. We investigate nonstationary DFB in gas systems, determine the oscillation transient times, and the energy gain due to the DFB. The possibility of using DFB in lasers for the ultraviolet band is discussed.
