The Physics Society of Iran Iranian Journal of Physics Research 1682-6957 2 4 2019 11 26 Second harmonic generation with DSR1-PMMA polymer films Second harmonic generation with DSR1-PMMA polymer films 235 235 493 FA H. Tajalli E. Mohajerani S. Ahmadi R. Kheradmand Journal Article 2019 11 26   The poling process of polymers doped with chromophores is of great importance for the nonlinear properties of these materials. So, after having optimized the poling condition the second harmonic generation (SHG) was measured for PMMA polymer doped with Disperse Red 1. The dependence of SHG intensity to the poling voltage and poling temperature have been experimentally studied. The relaxation of dopant orientation in the polymer matrix was also measured.   The poling process of polymers doped with chromophores is of great importance for the nonlinear properties of these materials.
