The two-dimensional nonlinear Schrödinger equation is commonly referred to as the "Nonlinear Schrödinger Equation" (NLS). It describes the evolution of slowly varying wave packets in nonlinear media and is significant in various fields, including nonlinear optics and fluid dynamics. In its general form, it includes a nonlinear term that accounts for the interactions of the wave function with itself.
Nonlinear absorption is the kind of absorption that occurs when materials are illuminated by a strong laser source. It's name is nonlinear because this type of absorption is proportional to square of intensity and higher orders. Remember Beer's law. Briefly dI/dz=-alfa*I-beta*I2-gamma*I3.. beta and gamma are the nonlinear absorption terms!
