Zusammenfassung:The primary importance of the power efficiency of second-harmonic generation (SHG) is determined by using the spatial shape of the fundamental input beam, its confocal parameter. The improvement of the fundamental input beam by using a spatial filter consisting of two apertures. The beam quality factor M2 of the improved fundamental beam was about 2.3. KCI Citation Count: 1
