Abstract

The problem of mode locking in linear arrays of lasers with gain-guided waveguides is considered on the basis of a theoretical analysis of Basov, Belenov, and Letokhov for diffraction-coupled lasers and also using the Vaĭnshteĭn approximation for diffraction losses. A simple calculation procedure, enabling an easy determination of the maximum wavelength difference between adjacent elements of gain-guided arrays, is proposed.
