Abstract

Self-focusing actions have central importance for most nonlinear optical effects. The critical power for self-focusing is commonly theoretically without considering a material's absorption. This paper aims to comprehensively review the critical power of intense laser beams in nonlinear media—numerical results based on the nonlinear wave equation. The critical power is a key parameter in nonlinear optics that determines when significant nonlinear effects occur using the nonlinear Schrodinger equation(NLSE), which is the fundamental equation of nonlinear optics, a nonparaxial approach is used for the mathematical formulation of critical power by dropping many approximations. Critical power is numerically calculated without any series expansion and compared with the result obtained by the popular paraxial approach.
