Experimental and computational studies on third-order urea salicylic acid single crystal for optoelectronic device applications

Manufacturing of urea co-crystals by spiral gas–solid two-phase flow (S-GSF) based on spiral jet mills: a continuous, solvent-free, and scalable mechanochemical method

“…S4 † shows the FT-IR spectra of USA, and the results are consistent with reported cases. 51 These results indicated the successful preparation of USA by S-GSF.…”

Third order nonlinearity examined by pulsed and CW lasers: an organic urea barbituric acid (UBA) single crystal for optical limiting application with DFT study

“…At high power laser intensity, the NLO material behaves as opaque and transmits entirely at low input intensity [76]. For incident energy at lowest, the UBA material obeys Beer-Lambert's law related to absorption and it starts to diverge from linearity at high laser intensity [69]. The plot (input intensity versus normalized transmittance) of optical limiting response of UBA crystal is revealed in figure 16.…”

“…From the observed CA curve, the peak followed by valley reveals that the UBA crystal exhibits negative nonlinear refractive index (means self-defocusing nature). The third order nonlinearity χ (3) , n 2 and β of the UBA compound were obtained using standard relation [68,69]. Table 9 gives third order nonlinear optical parameter values of the UBA crystal compared with other NLO materials.…”
