Study of the Second and Third Harmonics Generation in Lithium Triborate Single Crystal

In this paper, we investigate to approach the ideal conditions to optimized the performance of the single pure Lithium Triborate crystal (LBO) (The boronoxygen compound LiB3O5 is recognized as a new Nonlinear Optical crystal). which has dimension (5.955.95 5.95) mm3 as proposal element model for the combination of the Second Harmonics Generation (SHG) and Third Harmonics Generation with Nd Yag laser has the spectral wave length around 1.064 m and 532 nm. The main results are very satisfactory apply this proposal model as optimum controlling element for the combined application as, the second harmonics generator (SHG) and the Third Harmonics Generation at 1.064m and 532 nm.
