Laser items were initially introduced in the market as toys. The laser point took on the shape of a teddy bear, a star, a Christmas tree, a heart, or the peace sign. Fortunately these were not high power laser pointers. The red beam worked best on a dark background. Hours could be spent, darting it across the room, making your pet dog or cat run around in circles. But technology over the years has evolved into the production of high power laser pointers which can be lethal if not used responsibly.
The high power laser pointers are the ones that use power from 200 to 800 milliwats. These are available in a wide range of sizes and colors and come with accessories like a case and stand. The internet has opened the market for such but unless approved and certified by the FDA, they are extremely dangerous and illegal to use. The FDA checks whether safety measures like infrared filters, key switches, a metal body etc. have been used in the manufacture of the. While buying one, check for the FDA certification of the specifications. Do not go for something cheaper, as this may not even have the minimum one year warranty on the product.
The high power laser pointer can make a hole in paper, cut through electric tape, can light a fire, can burst a balloon, and can reach to identify a target that is more than 50 miles away. The beam can reach the stars, even through dense atmospheric layers. The medical use in performing specialized surgery is well known. Just imagine what it can do the human eye if indiscriminately used. The verdict would be 'damaged beyond repair'. The high power laser pointers are quite the sort of things that appeal to teenagers, wanting to show off to their friends. All the more reason why any manufacturer must insist on putting in writing (accompanying each such product) the hazards of undue exposure to a high power laser pointer.
The misuse of the high power laser pointer has made some countries ban laser pointers of higher power being used in non professional fields. Special permission is needed to use these in industry. In the US, it is illegal to point a laser beam at a helicopter or an aircraft, and is punishable by a stiff fine. Nor can lasers be pointed at moving vehicles or directed at a police officer. It is better to be safe than sorry. Any usage of a should be in controlled surroundings and done responsibly.
