Optical Second Harmonic Generation

We synthesized 4,4'-dinitrophenyl 1,1'-adipamide (DNPA) and studied optical second harmonic generation (SHG) in this organic material using the Kurtz method. The experimental analysis of SHG was made for a range of particle size of DNPA. It was observed that DNPA is nearly three times more SHG active than urea. It was also found that the compound is non-phasematchable and did not show any optical degradation for about an year when kept in ambient atmosphere.

Hygroscopic Nature

Solid solution of m-dinitrobenzene (DNB) and 4-bromo-2-nitro aniline (BNA) in urea (U) were prepared based on the prior study of phase diagram. The formation of solid solution was studied using the powder X-ray diffraction techniques. The powder X-ray data were also used for the study of particle size and strain in solid solution. The vapor sorption and desorption studies revealed that the hygroscopic character of urea was modified in solid solution. The study for the second harmonic generation efficiency of urea, DNB, BNA and the solid solution was done with fundamental of Nd:YAG laser (1064 nm).
