Excellent and Brilliant Blue Laser Pointer

More and more people know laser pointers through the efforts of laser sellers and companies, and green lasers and red ones have already occupied a big share all over the world. Furthermore, the emergence of the blue laser pointer supplies another wonderful choice for laser men.

As far as I know, blue laser pointer was first introduced by a Japanese person. At first, he invented a blue LED to provide a blue laser to consumers. That is also to say, blue LED is the embryonic form of the blue laser pointer. At present, the laser technology has becoming matured gradually and the blue laser pointers’ manufacture has reached a higher level.

Let me give you some information about the blue lasers. To start with, blue laser pointer is characterized with a wavelength of 445nm and the output power ranges from 5mW to 1W. It belongs to Laser Class III and the laser beam can reach from 400m to 8000m.

Second, the blue laser pointers have abundant applications in various fields. It can serve as a torch at night when you go camping. What’s more, high power blue lasers can light matches when you unfortunately encounter bad weather. And then, you can burn some wood to warm yourselves and do some cooking. Besides, nothing is more frustrated than being trapped in a jungle during hiking or camping. Blue laser pointer can be used as a distress signal because its beam is so bright that the policemen can see it clearly from long distance.

Third, blue laser pointer has another big advantage, that is, it is a helpful speech guide during conferences, educational lectures, public speech, etc. The speaker just needs to point the blue laser at the target, and the laser beam will turn into a dot. The audiences’ attentions are diverted with the movement of the blue dot. It is truly useful and time-saving.

Next, with a 1W blue laser pointer, you can do almost everything, such as burning metals, cutting tapes, laser shows, etc. The most important thing is the blue laser pointer is portable and can be put into the bag and even your pocket. It does not take up much room, but it can do you a big favor when you have demand.

Finally, there are still many applications waiting to be discovered by scientists or laser professionals. And we are looking forward to new surprises from blue laser pointers.
