Abstract

The Second Harmonic Generation has many applications. Since it is of particular importance, the current study examines its power and energy and irradiance conversion efficiencies for collimated Gaussian beams in presence of pump depletion and phase matching by using numerical calculations. In this paper, the optimal mode for the SHG (the Second Harmonic Generation) conversion efficiencies has been investigated in presence of pump depletion and phase matching, and it has been shown that the SHG conversion efficiencies in presence of pump depletion and phase matching depend only on the normalized incident peak irradiance. Therefore, the type of material used in the SHG can be selected properly according to the obtained results.
