It would be the greatest job that high power green laser pointer has got wide application in those of high-tech required area such as military, astronomy, scientific research etc. Among all series of laser crystals, green color laser diode is famous for its high bright and visible beam. How can green laser pointer so popular in the world?
Green color is the most sensitive color among all series of laser diodes, and the wavelength of 532nm has made green laser pointer has a good light dispersion in the atmospheres. The green laser pointer is especially bright in the night sky, thus it is especially loved by those of astronomy researchers and enthusiasts. The moment green laser is pointing at a star or other celestial objects; and it is so bright that you can feel your eye is almost touching the star.
