Abstract

Dye-doped polymers are excellent substitutes for liquid dyes. This paper presents a study of the nonlinear optical properties of phloxine B dye in ethanol and dye-doped polymer film by the Z-scan technique using pulsed Nd: YAG laser of wavelength 532 nm. At 1 mM concentration, the dye sample exhibited a nonlinear refractive coefficient (n2) of −2.50 × 10−8 and −3.6 × 10−8 cm2 /W, a nonlinear absorption coefficient (β) of −4.6 × 10−4 and −5.46 × 10−6 and susceptibility (χ 3 ) of 4.74 × 10−4 and 5.67 × 10−6 esu in ethanol and polymer, respectively. According to the results, the phloxine B dye in a solvent and a dye-doped polymer film exhibited negative nonlinearity. It is hence concluded that the phloxine B dye has excellent potential of use as nonlinear optical material..
