A nonlinear optical crystal of LPKDP crystal was grown at room temperature by slow evaporation technique. The size of the grown crystal is 11*7*2 mm3 at a growth rate of 0.55m/day. The single crystal X-ray diffraction analysis has been carried out to find the lattice parameters and powder x-Ray diffraction patterns has been recorded and indexed for the analysis of crystalline nature of the grown material. The FTIR spectrum of LPKDP crystal confirms the presence of functional groups. The Second Harmonic Generation efficiencies predict the non-linear property of the sample. Laser damage threshold study confirms the superiority of this crystal over conventional laser materials. Micro hardness studies of the grown crystal shows that as load increases, the hardness value also increases. The transparent nature of the material was confirmed by UV spectrum which is taken around 100-1100 nm
