“…The measured laser damage threshold value for PBPNPD crystal is 9.433 GW/ cm 2 . The LDT value of PBPNPD crystal is found to be higher than that of potassium dihydrogen phosphate and some of the important organic non-linear optical materials [29,30]. The high laser damage threshold value of PBPNPD crystal can find useful applications in high power laser devices.…”

Good quality single crystals of piperazinediium bis(4-nitrophenolate)dihydrate (PBPNPD) have been grown from aqueous solution by slow evaporation solution growth technique. Unit cell parameters of the grown crystal were confirmed by single crystal X-ray diffraction analysis and the synthesized compound is crystallized in triclinic system. Various functional groups and their vibrational frequencies were recognized from the FT-IR spectrum. The grown crystal has wider transparency nature in the visible region and the lower cut-off wavelength is found at 329 nm Thermal stability of the crystal was examined by recording the TGA/DTA curve. The dielectric studies were performed. The mechanical properties of the crystal were estimated by Vickers hardness test. The relative second harmonic efficiency (non-linear optical) of the compound is found to be 2.4 times greater than that of potassium dihydrogen phosphate (KDP). The laser damage threshold (LDT) for the grown crystal were measured as 9.43 GW/cm 2 with Nd:YAG laser assembly.

“…One of the essential criteria for the NLO crystal to perform as a device is that it needs high laser damage resistance because high optical intensities are involved in nonlinear process [28]. In the present experiment, an actively Q-switched Nd : YAG laser source with 6 ns pulse width and 10 Hz repetition rate was used.…”

2-Amino-4,6-dimethylpyrimidinium p-hydroxybenzoate (ADPHB), a novel organic material, was synthesized, and crystals were grown by slow evaporation solution growth method. The cell parameters and crystalline perfection of the grown crystal were studied by single crystal and powder X-ray diffraction analyses. The presence of various functional groups of the grown crystal was confirmed using Fourier Transform infrared spectral analysis. UV-Visible spectrum shows that ADPHB crystals have high transmittance in the range 305-900 nm. The refractive index and transient photoluminescence properties of the grown crystal were analyzed. The laser induced surface damage threshold, optical birefringence, and second harmonic generation efficiency of the grown crystal were studied.

“…Since high optical intensities are involved in nonlinear processes, the nonlinear materials must be able to withstand high power intensities [11]. This is the main criterion that restricts the application of many nonlinear organic materials.…”
