Abstract

Abstract: The gain competition is reported in an orthogonally linearly polarized (OLP) Nd:YVO4 laser. Two a –cut Nd:YVO4 crystals with their c –axes mutually orthogonal are employed as the gain medium. The wave equations for the gain-coupled polarized modes are derived and solved. A 32.7 W OLP laser was obtained and the output performances of the OLP laser are investigated experimentally and theoretically. The theoretical results agree well with the experimental ones, which indicates that the gain competition mechanism affects the output performance of this type of OLP laser significantly.
