Class 2 Green Laser Pointer How to view a label?

Who invented the laser? In 1960, a physicist named Theodore Maiman designed the first laser while working at the Hughes Research Laboratory in Malibu. His laser uses a synthetic ruby rod, plated with silver at both ends, cut in such a way that the beam bounces into it, gaining brightness before coming out the other side. The device emits a narrow, bright beam of light with a wavelength of 694 nanometers. Different methods are used to produce different colored lasers. green laser pointer are created by using simple semiconductor diodes to produce light. This consists of two semiconductors placed side by side, one on top of the other. On top of that, we usually find gallium arsenide, which is an electron-deficient material called a P-type semiconductor. At the bottom, gallium arsenide and selenium, which have extra electrons, are called N-type semiconductors. The two of them are stacked in a diode to form what is called a PN junction.

Because high powered laser produce condensed light, the nanometer (nM) scale is used to measure colors within the visible spectrum. Green at 532nm is the brightest color of the human eye. This means that a green laser pointer with the same power output as any other color will be seven to 10 times brighter. Due to this fact, green lasers are currently the most popular and universally desired color simply because they look vivid. You need at least 100mW to generate enough heat, and the higher the better. The laser is measured in milliwatts (mW), depending on the output of the laser, and can be handheld with power ranging from 5mW to 1000mW.
