A more powerful blue laser pointer
Laser melting cutting: laser melting metal material melting, and then through the nozzle coaxial with the beam blowing non-oxidizing gas (Ar, He, N, etc.), rely on the strong pressure of the gas to liquid metal discharge, forming cutting. Laser melting does not require complete vaporization of the metal, the energy required is only steam cutting 1 / laser melting cutting is mainly used for some difficult to oxidize materials or active metal cutting, such as stainless steel, titanium, aluminum and its alloys. The green laser pointer is actually the same type of laser used in blu-ray technology. Blue laser Pointers didn't exist until recently. Some laser Pointers that appear blue are actually purple, the last color in the visible spectrum. As far as demo Pointers are concerned, using a purple or blue laser pointer is a good change of pace, but a more powerful blue laser can also be used.

Depending on the power of the laser designator, these devices can be very dangerous, causing impaired vision, skin burns and even fires. That's why it's important for anyone operating lasers of any type to take appropriate precautions. The more powerful Class III laser should only be used when wearing proper protective gear, and no laser of any intensity should be directed at a person's eyes. As mentioned earlier, laser beams above 100mW can cause severe optical damage, while a 300mW high powered laser pointer can cause instant blindness if directed into someone's eye. Even a 30mW beam can cause serious eye damage, although the damage is usually not permanent and can heal in time.
