This research studied characteristics of the Nd:YAG laser with second harmonic generation (SHG) at 532 nm. It can be develop as a standard wavelength according to the recommendation made by the Comite International des Poids et Measures (CIPM). This study investigates various parameters that effect wavelength and laser power of the Nd:YAG laser such as injection current of diode laser, temperature of Nd:YAG crystal and second harmonic generator crystal. Its wavelength can be tuned in the range of standard wavelength at 532.24503 nm with 10-7 of stability.

A comparative study of the second harmonic generation in ZnO micro particles and nanorods has been experimentally studied by Kurtz technique using nanosecond pulsed Nd:YAG laser. The results have been theoretically explained by taking into account the quadrupole moment as well as surface nonlinearity. It was observed that the nanorods yield polarized second harmonic signal while the second harmonic signal obtained from the micro particles was unpolarized.
