Abstract
This paper presents an investigation of infrared (IR) radiation generation by nonlinear interaction of two visible laser beams in a metallic background. Two laser beams of Gaussian and Laguerre Gaussian (LG) profiles and background metals such as silver, copper, gold, and aluminum are utilized for IR generation. Effects of laser beam characteristics and structural properties of metals on the evolution of IR electric field amplitude are examined. Considering laser frequencies in the non- transparent region give rises to generation of IR surface plasmon (IRSP). An optimized relation is proposed for achieving efficient surface plasmon waves on a metal surface.
