Basic Laser Safety - Introduction
All lasers and laser light show systems have intrinsic dangers - even laser pointers! Observation of basic laser safety rules and the specific safety regulations of the jurisdiction in which you operate are essential.
We can NOT hope to review laser safety regulations on a jurisdiction by jurisdiction basis - there is just not enough space. Instead we will focus on some general safety information that applies across the board. If you do need specific safety information for a particular jurisdiction, contact the authorities in your area or the embassy for the country in question and ask.
A laser can be considered as a highly collimated source of extremely intense electromagnetic radiation that is defined by three characteristics: monochromatic, directional and coherent. Due to the temporal and spatial coherence of the laser beam it can be considered as a point source of phenomenal brightness than can easily exceed the brightness of the sun. Lasers are a more directional light source than any other common fixture such as stage lights or a follow-spot. The higher the optical output power of the laser, the greater the potential hazard.
