Comment on: 'Growth, Optical, Thermal, Mechanical, Laser Damage Threshold and Electrical Polarizability of Cadmium Chloride Doped L-Alanine (LACC) Single Crystal for Optoelectronic Applications' [J. Electron. Mater., 48, 7915 (2019)]

摘要

In a recent paper [J. Electron. Mater., 48, 7915 (2019)], Karnan et al. studied the physical properties of the cadmium chloride-doped L-alanine (LACC) single crystal. It is shown in this comment that the authors used a wrong approach to calculate the reflection coefficient. Erroneous values of the reflection coefficient were used to calculate the refractive index. Consequently, the reported values of the mentioned parameters, as well as other optical parameters that were calculated based on them, i.e. the real and imaginary parts of the third-order nonlinear optical susceptibility, are incorrect.
