Concentration effect on optical properties and optical limiting of PVA doped with nigrosin films

A novel azo compound derived from ethyl-4-amino benzoate: synthesis, nonlinear optical properties and DFT investigations

“…1. The synthesized compound chemical structure was confirmed by data of FT-Infrared, 13 C-NMR, 1 H-NMR, and mass spectra where the spectral information agree with expected structure.…”

“…The compound melting points were measured using a thermo Scientific (9100). The compound, 1 H-and 13 C-NMR, spectra were obtained using a Bruker 500 MHZ at 25 o C in solvent DMSO.…”

“…The laser beam interaction with nonlinear materials leads to variety of effects in the transverse dimensions viz., self-focusing (SF) and defocusing (SDF), spatial ring formation, self-phase modulation, etc., [1][2][3][4][5][6][7][8][9][10][11]. Materials having high nonlinear optical (NLO) third-order properties and ultra-fast response time led to considerable scientific activities for their potential applications viz., optical computing, optical phase conjugation, all-optical switching (AOS), holography, spatial dark soliton transmission, optical power limiting, harmonic generation [12][13][14][15][16][17][18][19][20][21][22][23][24][25] etc.…”
