1 see laser
Some people out of curiosity, trying to repair the fault or just purely for laser beam out stupid will look down to the lens of the laser.I don't care about your finger is close button, you have to take a battery or if the courage of the laser is working all over you, you never overlooks a laser.You never look down the barrel of a rifle and in the same way you should never overlook the laser.
Most of the portable laser eye injury occurs when someone is looking down their laser that is safe.A classic example is when a laser lovers looked down laser cleaning their shot when realized too late, they forgot the battery.The man now has a permanent blindness in their eyes.
2 laser in the plane
This looks like a very obvious not do laser, but the number of people pointing laser in the plane, it's not clear enough.
In addition to safety and hazard problem, pointed out that the laser in the plane is a federal crime in any country.So if you want to finally break the rock in the next 10 to 20 years in federal prison, please continue to be my guest.
If there is one thing wise laser fans hate, it is people in the aircraft laser.It is not only dangerous and stupid a be hardly worthy of belief, it is also responsible for the control of portable laser point hobbies may not have a legitimate future.
3 laser at
Another obvious "not to do laser", too many people don't seem to understand.High power laser is dangerous, your eyes, if you're a laser beam to a person, there is a chance you will hurt their eyes.It is so simple.

5 modified laser
Modification of a laser is when you use several methods of increasing power of laser diode and laser beam has more power.All of the laser, whether they are laser pointer or laser module can be modified, it sounds like a very cheap way of getting a high power laser.
