Good quality and transparent organic non-linear optical crystal 4-Hydroxy L-Proline (HLP) was grown by slow evaporation solution technique (SEST), which has the size of 10 × 5 × 5 mm3. The crystal system was identified and lattice parameters were measured by single-crystal X-ray diffraction. Functional groups of HLP are identified by FTIR spectrum measurement. The optical quality of the grown crystal was measured by UV–vis–NIR analysis. The mechanical stability of the grown HLP crystal was tested by Vickers microhardness analysis and the work hardening co-efficient value was also calculated. The dielectric constant and loss studies were carried out at various temperature to establish the dielectric nature of the HLP crystal. The frequency and temperature response of the dielectric property of the crystal was measured. The second order non-linear optical (NLO) property of the crystal was confirmed by powder Kurtz-Perry technique.
