How do green laser pointer work in our daily life

Posted on by

I would have to admire the elite professionals of laser diode technology, who have made laser pointers playing a significant part in our daily life. The laser pointer can not only used for presentation in teaching, speech, lecture, and business conference etc, but a wonderful gadget for joys and entertainment.

As a tool for presentation, nothing would compare with green laser pointer. With the most sensitive color to naked eyes, the green laser pointer is the brightest one among all series of laser diodes. What’s more, green laser pointer has a wavelength of 532nm, which is just among the medium range of wavelength, has perfect beam dispersion in atmosphere layer. As a result, green laser pointer is considered as the most visible and brightest laser diode and most commonly used in our daily life.

In our daily life, the green laser pointer is mainly used for pointing objects. The bright beam of green laser pointer is visible for hundred miles far away, thus it has been possible to watch objects in a long distance. In the night sky, people can use a green laser pointer to watch stars since the green color is especially bright in the evening. In the direction of bright visibly beam, people can find stars clearly and easily which cannot be seen through naked eyes. No need of waving arms hardly, people can just fix the beam of green laser pointer on a certain star and this high efficient tool has become a helpful gadget for those of astronomy hobbies and researchers.

Most of the time, people can choose a green laser pointer to pop balloons, light matches, burn plastic, rubbers, and papers, cut electric tapes etc. Higher power green laser pointer would always get better result than those of low powered lasers, and the laser pointer for burning experiments should at 100mW or even higher. Any time of playing burning games, people should pay enough attention and laser safety goggles are always necessary. The green laser pointer is really a wonderful tool in our daily life, and people should take enough care of the bright beam.
