With the development of technology, laser pointer has became one of the latest technical products, laser pointer finally applied in our daily life, while laser has been
existed for almost 60 years. Laser is a mysterious stuff that seldom has people
has a well knowledge about it, even though you own a laser pointer. So what is
laser pointer? As per the Wikipedia, laser is defined as "light
amplification by stimulated emission of radiation." And in modern level of
science and technology, the stimulation is accomplished by diode. Diode is an
integral part of laser pointer. Then what is the special light used for? Well,
laser is used for a variety purposes according to its almighty nature. The
purposes including pointing out aim in a presentation, museum interpretation,
sales house sand table indicating, aligning materials at construction sites,
guided tools. Play with pets at home. For doctors, it is used for cosmetic and
surgical procedures. For workers, it is used for carve up and alignment. Laser
is also being able to use in the hunting, hiking, shooting and the beauty
fields. Many items you encounter on a daily basis use laser, including CD and
DVD players, bar code scanner dental drills.
After a preliminary understanding of laser, it will
have many help in the next introduction of laser pointer. Laser pointer is a
small handheld portable device with a power source and a laser diode emitting a
very narrow coherent low-powered laser beam of visible light, intended to be
used to highlight something of interest by illuminating it with a small bright
spot of colored light. (Wikipedia) Laser is divided according to its output
power and wavelength. The output power is stated in type of milliwatt. Lasers
are divided into different safety classes on basis of output power. The
technical of output power as it relates to laser products is the power level of
the laser beam. A higher output power is brighter than a lower output power. So
does the cost. More powerful laser cost more.
Thus far, laser pointer has the different output
power from 1mW to 3000mW. According to FDA, only the laser pointer with output
power 5mW below meet with the safety standards and available for market. But it
doesn't mean that it is forbidden to produce or to own a laser pointer more
than 5mW, that is quite a ridiculous idea. What the FDA means is to let users
to pay attention to the safety operation. More than 5mW laser pointer will lead
the unimaginable damage. 50mW is able to burn cigarette or wear out the balloon
in a flash. Even not to mention your eye. But we truly need more than 5mW laser
pointer. Take stargazing for example, 5mW laser pointer is difficult to clearly
indicate. The higher the power, the bigger the energy. The high power laser
pointer even be able to cut board and glass pane.
So is there an all-in-one solution? Maybe a pair of
laser safety goggles can be easily solve our scruple. Wearing laser safety
goggles can protect eyes. But at the same time, it is also need to pay special
attention that don't shoot laser on the glaze with reflection ability, and
human body especially. Power of laser is the most important reason that laser
can be popular and can't be replaced.
