Physical origin of observed nonlinearities in Poly(1-naphthyl methacrylate):Using a single transistor–transistor logic modulated laser beam

引用

Chinese Physics B 2013年第11期22卷 331-336页

作者： qusay m.A.Hassan Hussain A.Badran Alaa Y.AL-Ahmad Chassib A.Emshary Department of Physics College of Education University of Basrah

A thermal lens technique is adopted using a single modulated continuous wave （cw） 532-nm laser beam to evaluate the nonlinear refractive index n2, and the thermo-optic coefficient dn/dT, in polymer Poly （1-naphthyl methacrylate）（P-1-Nm） dissolved in chloroform, tetrahydrofuran （THF）, and dimethyl sulfoxide （DmSO） solvents. The results are compared with Z-scan and diffraction ring techniques. The comparison reveals the effectiveness and the simplicity of the TTL modulation technique. The physical origin is discussed for the obtained results.
