I am looking for information on how to add a laser aiming pointer to my 100W CO2 laser.
I bought a ZnSe window to use as the mirror for the aiming pointer.
Do I just place the mirror at 45 degrees to the main laser beam and then shine the aiming beam 90 degrees to the main laser beam?
Is there a different angle for optimum performance?
Any recommendation for the laser pointer itself?
