subject: Laser Technology And The Laser Pointer [print this page] The technology in lasers has been improving a lot for the last 20 years. Many industries have found many uses for lasers may it be in entertainment, defense, weaponry, research, and science and technology. The invention of the handheld laser device called laser pointer has given fascination to people worldwide because of its many uses, not only as a pointer. Many astronomers find it best to observe heavenly bodies at night by using powerful laser as pointers. The military use these lasers during trainings of their soldiers especially as a big help in using weapons. Since it is released commercially, some people who are just fascinated by the technology want to own it as a personal gadget or a toy.
Whatever purpose you may have in owning this device as long as it is good then there will be no problems. Being responsible as owner of this laser device is important because you might not know the dangers that may arise if misused. The first laser pointers are available in only one laser beam color which is red. During its time, the public was already warned that it can be dangerous to the eye. Now that it is created more powerful in many different color variants, the more that we need to be careful.
The creation of the laser pointer is not simple. You can see that there are so many green laser pointer products being advertised now but the technology used is a bit complex. In order to achieve the green laser pointer beam color, they need to align the crystal laser diodes to attain the green laser wavelength, which is 532nm. This is the same with other laser beam colors with different frequencies in nanometer (nm).
If you have decided to buy your own laser device, you have to take good care of it and use it properly. As a responsible owner, you have to keep it away from the irresponsible ones. Avoid dropping or shaking the device for it may impair the production of laser.
