Linear and Nonlinear Optical Properties of L- Histidinium Perchlorate (LHPCl) Single Crystal
L- Histidinium Perchlorate, a semi organic nonlinear optical material was grown by solution growth method. The absorption studies show minimum absorption in the entire visible region. The optical band gap (Eg) value of the grown crystal is obtained from the tauc’s plot of (αhν)2 vs hν which was determined by extrapolating the linear region of the curve to the hν axis where (αhν)2=0. Furthermore linear optical parameters such as Extinction coefficient, Reflectance, Refractive index, Complex dielectric constant and Optical conductivity are calculated and its variation with incident photon energy is analyzed. Second Harmonic Generating (SHG) efficiency of the candidate material was determined by Nd:YAG Q-switched laser Kurtz powder techinqe and its 3.19 times greater than KDP.
