Hi there.

I have a laser diode with divergence angles of 30 degrees and 6 degrees in the x and y directions, respectively. I represented the divergence angles in two fields: 30 degrees in the x direction and 6 degrees in the y direction. I want to achieve the minimum spot size where the two fields overlap. However, when I perform the optimization, I get results where each field has its minimum spot size within its own field. How can I obtain the minimum spot size where the fields overlap?
