The Laser Pointers are not in Science Fiction Anymore

Posted Dec 07 2012 7:54am
The advances in laser technology application over the past few decades had made people wonder what life would be like if we had not discovered the beauty of the process. "Light Amplification by Stimulated Emission of Radiation" is a process which is now known as Laser. We can find
532nm Lasers in multitude of consumer products such as printer, scanner, video CD, medical equipment, laser pointer, etc. Laser has not surprisingly become our faithful servant just like pen and pencil. The use of laser pointer for teaching and presentation is very much a routine. However, how many users are aware of the potential problems associated with its use?

Conventional laser pointer usually comes with a low-powered red laser. The laser beam of the pointer is generated by a laser diode which produces the red wavelength. Since the power of the laser beam is relatively low, proper use of the pointer will not normally cause any safety concerns. Recently, a more attractive green laser pointer is available in the market. The green laser pointer has a definite advantage over the red as human eyes' response to the green wavelength is far more sensitive than the red. The green dot appears much brighter to the audience than the red dot. However, the laser diode which produces the green wavelength is not commonly available and it takes a complicated set-up to generate the green beam. With the set-up, the power of the green laser pointer can easily go over 100mW, whereas, the power of the conventional red pointer is normally less

These Cheap Laser Pointers should never be pointed towards other. Always, should be pointed facing towards wall or the floor. This might cause injuries to others.
These powerful laser pointers should never be repaired on own as they are made with powerful lenses which might damage if repaired on own. In considering one particular brand, look out for the high end components, high stability beam power and output power. These three pointers are your ways to finding the perfect laser pointer pen.
