Abstract

n this paper, we have studied the linear optical properties and nonlinear optical Phase Conjugation properties of two azo-dye-doped polymer films by considering organic dyes disperse orange (DO-25) and disperse yellow (DY-7) doped in a polymer matrixPolymethyl methacrylate methacrylic acid (PMMA-MA). The nonlinear optical phase conjugation properties are studied usingDegenerate Four-Wave Mixing set-up using 532 nm wavelength CW laser beam. The effect of dye concentration, the intensity of backward,forward pump, and the inter-beam angle between the probe and forward pump beam on phase conjugation reflectivity are also studied andcompared. ; Other ; {"references" : [ "[1] Y.R.
