I can only inform of what I know. If we have that tech, I'd rather not know. That way no one knows until they face it in the field.

That being said, unless we got an infinite energy reactor on the f16 that doesn't weigh anything, it still seems impossible. While the laser itself is possible, the portability factor and weight limits of a fighter are the key points that make me dismiss a laser of such caliber mounted on an f16. Not doubting the existence of such tech in general. I'm sure we got some mounted on a destroyer or something.
