Figure 6
Experimental results of SHG signal generated with LG\(_{31}\) beam astigmatically transformed with various tilting angles \(\alpha \in\) [\(0^\circ , 15^\circ\)] to serve as the fundamental input. The first row correspond to the intensity profile collected at plane (iii). From the second and to the fourth row are presented intensity, phase profile and electric field distribution of the upconverted beam captured at plane (iv).
