Focus Investigation behind Aspherical Lens

High-power laser diodes often show asymmetric divergence and astigmatism between two directions. As an example, a laser diode is firstly collimated by an objective, then focused by an aspherical lens, and the evolution of the field in focal region is investigated in VirtualLab. The influence from the astigmatism on the field in focal region is clearly presented, with comparison to the case without astigmatism.
