Blue Laser Pointers
The blue laser pointers were introduced by a Japanese researched named, Shuji Nakamura. The idea behind this construction was to use a bright blue LED to provide a blue laser to the consumer. The blue LED was the former model used to produce this kind of laser pointer. It allowed for the creation of the blue laser which is of tremendous use today. Not only is this blue laser pointer used for DVD players but it has also allowed for handheld lasers to be produced in this form. Thus, DVD players no longer need to be created with the red laser which allowed for shorter wavelength. Also, the blue laser pointer adds to the red and green pointers that were already available in the market.
Features of Blue Laser Pointers
The blue laser pointers are becoming increasingly common as new technology becomes more rampant. The construction of the blue lasers is very similar to that of the green lasers. The blue laser pointers are created by doubling the radiation produced by the lasers to the diode-pumped crystal. This kind of pointer is produced for mass consumption and sold in the same manner in the market. The kind of crystals employed for these kind of lasers depend on the kind of output power which is required for their use. The higher the power, the stronger the crystal employed while the lower powers require weaker crystals. There are certain semiconductors which allow for blue lights to be used without doubling the frequency.
Specifications of Blue Laser Pointers
The blue laser pointers come with a high wavelength which can amount to 473 nm. The output power of the blue laser is also incredibly high as these laser pointers generally fall above 5 millwatts. The diameter of the aperture of the blue laser pointers is also incredibly high in terms of millimeters.
Uses of Blue Laser Pointers
Blue laser pointers are used for various activities. The first is its use for astronomy for those who prefer to look at the constellations. This kind of pointer is perfect for those who hold star gazing parties or those who conduct lectures or classes on astronomy. The blue laser pointer allows for individuals to mount their lasers on telescopes which can then be directed towards a certain position in the sky. The military uses laser pointers for attacking aircraft. The blue laser pointers can also be used for hiking and other camping activities
