been there tried that move on not worth it. You have to mount the ball ON the die of the laser. It is no possible out of a cleanroom with special adhesives. If you succeed you will have a tem00 beam on a single mode diode. You also lose a lot of power.
Here is the bottom line. You can change the laws of physics. Stick to simple lens correction or get better lasers.
