Ultrafast photoexcitation dynamics of N-benzyl-2-Me-4-nitroaniline was studied with femtosecond time-resolved absorption spectroscopy. The photo-induced absorption spectrum was found to consist of 3 transient components with different decay times. A 260 fs-decay time stimulated emission appeared during a geometrical relaxation from a charge-transfer excited state to a geometrically relaxed excited state. A following energy relaxation of the geometrically relaxed excited state was completed within 680 fs. Third 2.6 ps decay time reflected a cooling process of hot electrons in a ground state potential.

Fujiwara, Masazumi published the artcileSecond order nonlinear optical properties of the single crystal of N-benzyl 2-methyl-4-nitroaniline: anomalous enhancement of the d₃₃₃ component and its possible origin, Quality Control of 201157-13-3, the publication is Japanese Journal of Applied Physics, Part 1: Regular Papers, Brief Communications & Review Papers (2006), 45(11), 8676-8685, database is CAplus.

A single crystal of N-benzyl 2-methyl-4-nitroaniline (BNA) whose dimensions were 8 ¡Á 10 mm (diameter ¡Á length) was grown using a vertical Bridgman method with sufficient optical transparency for spectroscopic use. Polarized reflection spectra of the crystal were measured in order to determine its linear optical parameters (refractive indexes and extinction coefficients). The relative magnitudes of the d-tensor components of the crystal were determined to be d₃₃₃ = (17 ¡À 9) ¡Á d₃₂₂, d₃₂₂ > d₃₁₁, d₃₁₁ ? 0 from polarization dependencies of the second harmonic generation. These results are in disagreement with previously reported theor. studies, in which the effects of intermol. interactions were completely neglected. Here, we have included these intermol. interactions in the calculations assuming the presence of supra-mol. clusters. We conclude that the anomalous enhancement of d₃₃₃ is due to the interactions along the direction of the hydrogen bonds in the crystal and the resonance effect.

Nonlinear optical mols. can be vacuum deposited into uniform thin films using thermal evaporation Alignment order can be achieved during thin film deposition by an in-plane elec. field poling using electrodes patterned on the substrate. Electro-optic (EO) coefficients, r₃₃ and r₁₃ are independently measured using Young’s interferometry technique. Thin-films of N-benzyl-2-methyl-4-nitroaniline (BNA) can exhibit an EO coefficient, r₃₃, comparable to that of BNA single crystals. EO coefficients of BNA at different poling fields, wavelengths, and frequencies are investigated.

We report on high-energy terahertz pulses by optical rectification (OR) in the organic crystal N-benzyl-2-methyl-4-nitroaniline (BNA) directly pumped by a conventional Ti:sapphire amplifier. The simple scheme provides an optical-to-terahertz conversion efficiency of 0.25% when pumped by collimated laser pulses with duration of 50 fs and a central wavelength of 800 nm. The generated radiation spans frequencies between 0.2 and 3 THz. We measured the damage threshold, as well as the dependency of the conversion efficiency on the pump fluence, pump wavelength, and pulse duration.

Thirupugalmani, K. published the artcileInfluence of polar solvents on growth of potentially NLO active organic single crystals of N-benzyl-2-methyl-4-nitroaniline and their efficiency in terahertz generation, Recommanded Product: N-Benzyl-2-methyl-4-nitroaniline, the publication is CrystEngComm (2017), 19(19), 2623-2631, database is CAplus.

We report on the growth of N-benzyl-2-methyl-4-nitroaniline (BNA) crystals by a solution growth method using certain polar protic and aprotic solvents (single or mixed). It was observed that the morphol. of the BNA crystals could be influenced by the solvents used and that the growth was, with certain exceptions, predominant along the crystallog. b axis. Attempts to grow large BNA crystals from these solvents showed that the majority of these polar solvent mols. tended to get adsorbed preferentially along the polar +c and/or -c axes/axis. The bulk and surface qualities of the grown crystals were observed to be influenced by the solvents employed to grow the BNA crystals and the results of THz measurements obtained for the crystals grown from selected solvents were also found to corroborate these observations. A systematic approach has shown that the BNA crystals grown from one of the polar aprotic solvents, which is presumably reported for the first time for this crystal, exhibited a relatively higher THz efficiency. It is further understood that this particular solvent created a favorable solute-solvent environment at the progressing crystal-solution interface which improved the overall quality of the BNA single crystals and resulted in the significant enhancement in the THz efficiencies.

Tangen, Isaac C. published the artcileComprehensive characterization of terahertz generation with the organic crystal BNA, Quality Control of 201157-13-3, the publication is Journal of the Optical Society of America B: Optical Physics (2021), 38(9), 420597, database is CAplus.

We characterize the terahertz (THz) generation of N-benzyl-2-methyl-4-nitroaniline (BNA), with crystals ranging in thickness from 123 to 700¦Ìm. We compare excitation using 800 nm and 1250 to 1500 nm wavelengths. Pumping BNA with 800 nm wavelengths and longer near-IR wavelengths results in a broad spectrum, producing out to 6 THz using a 100 fs pump, provided the BNA crystal is thin enough. ~200¦Ìm or thinner crystals are required to produce a broad spectrum with an 800 nm pump, whereas ~300¦Ìm thick crystals are optimal for broadband THz generation using the longer wavelengths. We report the favorable THz generation and optical characteristics of our BNA crystals that make them attractive for broadband, high-field THz generation, and we also compare differences in THz properties relative to BNA characteristics reported in other works.

Piela, Katarzyna published the artcilePolymorphism and cold crystallization in optically nonlinear N-benzyl-2-methyl-4-nitroaniline crystal studied by X-ray diffraction, calorimetry and Raman spectroscopy, Quality Control of 201157-13-3, the publication is Journal of Molecular Structure (2011), 991(1-3), 42-49, database is CAplus.

Polymorphism of N-benzyl-2-methyl-4-nitroaniline (BNA), a terahertz emitter and frequency doubler, was detected and the crystal structures of orthorhombic and monoclinic polymorphs have been determined at room temperature The differential scanning calorimetry (DSC) revealed monotropic phase transition of the monoclinic BNA crystal at 362 K and during re-heating, after the molten BNA cooling, the cold crystallization of both polymorphs. The variable-temperature Raman spectra in the 700-1700 cm^-1 range evidenced the polymorphic transformation from the monoclinic to the orthorhombic structure, the latter stable in the wide temperature range. The comparison of the crystal structures, DSC curves, FT-IR and Raman spectra of the two polymorphs allowed the authors to recognize the N-H¡¤¡¤¡¤O hydrogen bond in the orthorhombic and C-H¡¤¡¤¡¤O hydrogen bond in the monoclinic one as well as other intermol. interactions. The role of dynamic disorder, intra- and intermol. charge transfers in the mol. mechanism of optical nonlinearity is discussed.

We report on terahertz (THz) generation from organic crystal N-benzyl-2-methyl-4-nitroaniline using a 1.15-1.55 ¦Ìm near IR pump. We observed a very large emission spectrum extending up to 7 THz, compared to 2.5 THz from a Ti:Sa pump in previous reports. The maximum optical-to-THz conversion efficiency in our experiment was 0.8% at a repetition rate of 1 kHz and without saturation, leading to a peak elec. field of 1 GV/m. Our results show pronounced phase matching privilege for intense terahertz generation using a pump in the 1.15-1.25 ¦Ìm range where high energy near IR pump sources operate.

Full elements of second-order nonlinear optical (NLO) tensor can be completely characterized for an organic NLO crystal for the first time. As-grown bulk N-benzyl-2-methyl-4-nitroaniline (BNA) crystal was processed to expose (100) and (010) crystal orientations with fine optical surfaces by using precision lathe and diamond blade. Then, every five nonvanishing second-order NLO coefficient of BNA can be determined quant. using the precisely processed crystals based on 1st-kind Maker fringe measurements. Our method makes it possible to clarify uncertain NLO property of any organic materials and to accelerate application study via precise device fabrications even for fragile organic materials.

The role of anharmonicity, vibronic couplings and intermol. H bonds and of the N-benzyl substituent are discussed and the origin of 2nd harmonic generation in the orthorhombic BNA crystal is proposed.
