“…Laser damage threshold value for grown LTP crystal was measured using single shot laser pulses from Nd:YAG laser source with 10 ns pulse width and at 10 Hz repetition rate. [17][18][19] 2.2.5 Birefringence analysis. Optical homogeneity and birefringence of the crystal was evaluated using modied channel spectrum (MCS) experimental setup, which was based on the principle of channelled spectra.…”

“…The energy density was calculated using the formula E/A where E is the input energy and A is the area of circular spot. 17,18 The value obtained for 1 pulse per second is tabulated in Table 1. LTP was observed to possess reasonably high laser damage threshold value compared to other well-known organic and inorganic crystals, such as KDP and urea, used for NLO applications.…”

“…As evident from the figure, the valley-shaped curve shows a maximum decrease in transmission about the focus Z ¼ 0. This phenomenon is referred to as reverse saturation absorption, indicating nonlinear absorption (Rani et al, 2013). The experimentally recorded Z-scan curve (represented by bubble symbols) is fitted using standard nonlinear transmission equations (shown as a solid line) to obtain the optical nonlinearity coefficient.…”

“…Advances in research and technology in various fields are highly dependent on crystals. Crystals displaying favourable piezoelectric, ferroelectric and nonlinear properties are in great demand, on account of their suitability for many applications (Senthil Pandian et al, 2012;Rani et al, 2013;Shkir et al, 2013). Consequently, much work on the growth of bulk single crystals is being concentrated on detecting the feasibility and workability of crystals for device fabrication.…”

To achieve good quality bulk size crystal growth, an assessment of the nucleation kinetics of a semi‐organic L‐leucine hydrobromide (L‐LHBr) crystal was carried out using double‐distilled water as solvent medium. The effect on metastable zone width (MSZW) with increasing temperature and on induction period with varied supersaturation level was determined experimentally and was found to be very well in accordance with the nucleation theory prospects. Thereafter, various other nucleation parameters, such as Gibbs free energy and interfacial energy, were also determined. The knowledge of these nucleation parameters indicated the requisite temperature domain and the appropriate growth technique, leading to the successful single‐crystal growth of L‐LHBr by slow cooling in the temperature range 298–291 K. The cooling rate of 0.25 K per day was optimized after repeated trials. X‐ray diffraction and Raman analysis were performed on grown crystals for the verification of the material. High‐resolution X‐ray diffraction analysis was used to assess the crystalline perfection of the grown crystals. To further explore the properties of the grown crystals, photoluminescence and time decay studies, etching analysis, and Z‐scan measurements were performed.

“…Laser damage threshold analysis was carried out using a Nd:YAG laser having a wavelength of 1064 nm. 27 The observed values of the laser damage threshold after a single shot and multiple shots are given in Table 3. From these analyses we understood that the single shot laser damage is higher than that of multiple shot damage threshold.…”

The semi-organic non linear optical single crystal of L-proline cadmium chloride monohydrate was successfully synthesized and the single crystal was grown by a slow evaporation solution growth technique, using double distilled water as the solvent. The lattice dimensions of the grown crystal were examined by powder X-ray diffraction and it was found to belong to the orthorhombic crystal system with a noncentrosymmetric space group. Its crystallinity was assessed by a high resolution X-ray diffraction method and its structural imperfections were recorded using X-ray topography. The presence of functional groups was identified from heteronuclear correlation methods. Its optical behavior was examined by birefringence and photoluminescence and its optical constants were determined from UV-Vis. analysis. Its thermal and third order nonlinear optical properties were characterised by photopyroelectric and Z-scan methods, respectively. The mechanical and ferroelectric behavior was also assessed on the grown single crystal of L-proline cadmium chloride monohydrate.
