The 808nm infrared laser excitation wavelength of the green nonlinear crystal is used to generate 1064nm infrared light, which is then multiplied by the 532nm green light belonging to a solid-state laser. Some green laser pointers operate in pulsed or near continuous mode to reduce cooling problems and extend battery life. It was recently announced that the frequency of the green laser needs to be doubled to increase efficiency. The wavelength of the red laser laser diode is different, and its structure is the simplest. Basically, each diode has only one battery. The red laser pointer first appeared in the 1980s. It was a huge and heavy device, worth hundreds of dollars, but now it is very small and very cheap. In recent years, a solid-state laser (Dpss) red laser pointer with a wavelength of 671nm has appeared.
Are you looking for high-potential lasers or infrared Laser Pointer crows to locate and aim in the army? Different laser tools will find different values for each army. The 532nm green laser pointer is the brightest light color in the human eye, but it is often misunderstood as being very suitable for engraving. The actual situation is not the case, because the color does not determine the engraving ability, it is determined by the force itself. For example, 200mW green will burn like any other 200mW color, and vice versa. There is also a view that in terms of the use and visual recognition of people with congenital color vision defects during surgery, green lasers are easier to detect than red lasers. DPSS (diode-pumped solid-state laser) products are widely used in green leather pens with low prices. However, due to the large number of optical equipment parts and complex electronic circuits, they are generally more expensive than red laser pointers.
