of course you do not know me or anything about my capabilities and the wild ass projects I have pulled off in the past.
True, I don't, however I am very familiar with DPSS Near IR lasers, the only thing you will be burning with 808 is likely your eye balls.

II-VI Infrared or Mellor will get you a good lens, you do however have some other issues to fix first (or at least consider)

It's M^2 is <20, that's about as bad as it gets (Typically the cheapest Chinese rubbish tube has an M^2 of 2.2 - 2.5 with RF sources being 1.1 - 1.2)
The spot is square
It's operating temperature is 10-35 degrees C
It has a warm up time of 5 minutes

In effect you have a bench top lab laser that is totally the wrong thing to put into any kind of CNC system.

Can it be done? yes

Is there any point what so ever in doing so? no
