  1. Look Directly Down the Laser

Several people, out of curiosity, trying to correct a fault or simply out of sheer stupidity will look down at a laser in the lens where the laser beam comes out. I do not care if your finger is on the power button, if you took out the batteries or if the gills of the laser spread all over your workbench never look down with a laser cutter. You will not ever look down the barrel of a rifle and in the similar way you should never look down at the laser.

  1. Point the Laser to People

High power lasers are very dangerous to the eyes, if you aim a laser at someone, there’s a chance you’ll hurt your eyes. It’s that easy. Of course you could be aiming with the 500mW laser pointer that can light cigars in the hand, the back of the head or on the bridge of the nose, where everybody does know it is safe. However, what happens if you move, your hand slips, someone hits you or anyone and the same things that can go wrong? What happens is that in that fraction of a second you are dependable for that person losing partially or completely the vision in that eye.

  1. Point the Laser to the Aircraft

This is seen as something very obvious that has nothing to do with a laser, but judging by the number of people who point to lasers on the plane, it’s not noticeable enough. In addition to the safety issues and hazards involved, aiming lasers at aircraft is a central offense in almost every country.

The main problem with modifying the lasers is that the lasers are not designed to handle the highest power levels and changing them will usually destroy or damage the lasers.

But if you have spent several hundred dollars hard earned to buy your laser cutter machine, leave it as it is.
