Abstract
Nd: YAG laser has been a versatile tool for variety of material processing in the modern manufacturing industries. Apart from the easy manipulation and robustness of Nd: YAG laser beam, its wavelength absorbed by wide range of materials. Therefore, the possibility of controlling and précised values for prominent operating parameters such as average peak power, average peak power density (APPD), mean power, pulse duration, pulse energy, pulse repetition rate, interaction, pulse overlap theory and its mathematical relationships were discussed for pulsed and continuous wave. Hence, the selection of satisfactory combinations of associated parameters to produce efficient and effective material processing with reduced defects.
