The ideal color strength laser pens gun should be “no color” in the infrared, and you see the blue laser may not necessarily be the color itself, it is very likely that the luminous light hit the target in the high temperature region produced by laser emitting laser itself will be hot, if large power or it will burst a cooling device.
If you do not want every shot to CD, then give it an evaporative cooling device, like the laser pens gun, the cooling liquid natural water can not be so low things, then use liquid nitrogen, affordable, safe and clean, high concealment, just need your gun. A coolant and exhaust port.
When it comes to the powerful laser pens device, it must mention the laser cutting machine, which is now more conventional can rival the laser gun thing, it is indeed very small, just to support it to work there is a lot of things.
Laser pens gun just need that little things below the white black sub center of the beam on the above, it can be like a tofu cut anything you want to cut any metal you want to cut it, just for killing the target is too small, you need a little rough. Plus a handheld device for cooling equipment and inexhaustible power, finally add a cool shell, is a laser gun.
