Abstract
DBF laser of this type is based on the modulation of activator concentration being introduced into the crystal during the growth process.1 As a result, spatial periodic structures of activator concentration and refractive index are formed with the period L (q = 2π/Λ) and profile determined by crystal growth conditions.2 Rescattering of the counter-running waves of generation on the structures leads to the DFB.
