1, the laser at any time must not point to their own or other people's eyes, even if the laser will be wrong in the case of closing the possibility.
2, the laser can not illuminate any reflective surface or smooth surface, the reflection of the laser is very good, when shining on the reflective surface will produce reflection, if it happens to illuminate people's eyes, can cause damage.
3, the laser is not a toy, can not be used for children, intelligence is not complete, do not understand the characteristics of the laser, in this case, it is easy to cause damage.
4, the use of laser should wear special goggles, for invisible laser, this point is particularly important.
5, the laser can not shine on vehicles, aircraft and other vehicles with people.
6, pay attention to the safety of the laser battery, to prevent others from removing the battery to cause short circuit combustion or battery explosion accidents.
 
Laser emission principle and the particularity of the process of laser has decided that ordinary light does not have the characteristics: that is, three good (monochromatic good, good coherence, good direction) a high (high brightness).
