Well i dont think so but you can get arrested if you do something bad with the etc, shine them at aircraft, blind some one and so on ...
In general lasers of 1mW or lower power are legal without a license. Lasers of higher power must be licensed, the users have special training, and often automatic cutoff mechanisms must be installed to shut off the laser if someone enters the room. Following those restrictions any laser can be legal.
However even with a 1mW laser, don't aim it at a car, airplane, etc. It might briefly blind the driver, pilot, etc. causing an accident that you would be legally responsible for! The laser may be legal but the action isn't.
True. Rubies are used in certain types of lasers, specifically ruby lasers, which were among the first lasers developed. These lasers utilize synthetic ruby crystals, which emit red light when stimulated by a flash of light. The unique properties of ruby make it suitable for applications in various fields, including medicine and telecommunications.
No, most lasers emit light at a different frequency than UV.
All noble gases - He, Ne, Ar, Kr, Xe - were used in lasers.
Yes, scandium is sometimes used in the production of solid-state lasers, particularly in scandium-doped crystals or materials. Scandium can help improve the efficiency and performance of these lasers by enhancing certain properties of the laser material.
Yes.
All lasers are illegal if they are higher than 5mw green and blue lasers are not illegal if they are 5mw or less.
anything above 5mw is illegal, also green and blue lasers are illegal in Ireland.
No green lasers are not illegal just do not point them at aircraft
Yes Lasers are illegal because there is a law about it that a kid killed himself and now they are illegal
No
No
No green lasers are completely legal, just don't point them at occupied vehicles or aircrafts.
No..lol Lasers above 5mW are illegal in Florida. While, you can get a strong one at normal conditions.
Lasers differ in price between manufactures and quality. i have found a 100 mw laser for $16.00. But as a buyer you have to be careful, ordering any laser over 5mw to the U.S is illegal. I do not know how strictly it is enforced. Correction to your reply: Lasers over 5mw are illegal to IMPORT to the USA. 100% legal to purchase in the US
im sure it is illegal in Australia theres been many cases of people aiming industrial size lasers at police helicopters. they fined them heaps and conviscatad the equipment...
