Fifth-order optical nonlinearity of pseudoisocyanine solution at 529 nm

Evidence of the interference between third- and fifth-order nonlinear optical processes is shown in the studies of pseudoisocyanine (PIC) dye aqueous solution using 529 nm radiation (t = 475 fs) and the Z -scan technique. The third-order nonlinear refractive index of the PIC solution was measured to... View More
