- Hazards of lasers can be separated into two general categories1:
- Beam related hazards to eyes and skin
- Non-beam hazards, such as electrical and chemical hazards
- Laser light can be emitted in a tight beam that does not grow in size at a distance from the laser. This means that the same degree of hazard can be present both close to and far from the laser.
- The eye can focus a laser beam to a very small, intense spot on its retina, which can result in a burn or blind spot.

Laser safety - Wikipedia
While most of the danger of lasers comes from the beam itself, there are certain non-beam hazards that are often associated with use of laser systems. Many lasers are high voltage devices, typically 400 V upward for a small 5 mJ pulsed laser, and exceeding many kilovolts in higher powered lasers. This, coupled with high pressure water for cooling the laser and other associated electrical equipment, can create a greater hazard than the laser beam itself.
