Optimization of Variable Parameters in Diode Pumped SHG Nd-YAG Lasers

Abstract

Second Harmonic Generation (SHG) produces many parameters which are the consequences of interaction of fundamental incident power and those created inside the second harmonic cavity, external employing monolithic crystals. In this study, a low power of continuous wave (CW) Nd-YAG laser with principal output of and maximum power of theoretically was used. The crystal is [MgO: LiNbO3] which is lithium niobate, magnesium oxide doped with specific optical properties explained, the parameters in questions are both reflection and circulating powers in the second harmonic cavity. Both are functions of fundamental incident power . The results are compared with their experimental correspondents and interpretation for the causes is discussed.
