Here's a cropped photo of the spot from my 6W NUBM44 laser diode expanded to about 2 inches diameter. Most of the power is concentrated in a dot at the center, but I also have these huge wings left and right of the spot, can anyone tell me why? I'm using a 2 inch OD PCX lens in an expander setup and don't know how to get rid of these wings.
I suppose I could simply put a mask over the output of my lens and cut them off before they can leave the lens, but I prefer an optic solution.
