The difference between green laser pointer and red laser pointer
On the front end, at the touch of a button, the desired red laser appears, which is only one wavelength, strong beam and high intensity compared to incandescent light. When pointing at architectural details, using a laser pointer is a convenient way to get to the point without any extra effort. The laser pointer is very precise and easy to use when showing long distances. They are useful in dark spaces, but are especially useful outdoors, especially with green laser pointers. The laser works through a series of liquid crystals that self-assemble into a spiral pattern, which then acts as a laser cavity. These helices are chiral, meaning they move in the same direction, allowing tuning over a wide range of wavelengths.
I believe that many sellers are not very satisfied with the low-power and medium-power high power laser pointer they own. The current maximum power is 50000mw. No matter how long the continuous spot projection lasts, this industrially designed laser pointer efficiently provides ultra-stable and reliable spot projection service. The 532nm green laser is emitted from an 808nm laser diode pumped crystal. The light from the green laser pointer is more clearly identified. At the request of the majority of fans, we have developed some 50000mw new products to give back to the fans. lectures, presentations and reports. Green has the most obvious effect in the laser source RGB, which is farther than the same power and other colors, and the effect is more obvious, which is very suitable for outdoor use. Note that whether it is red light, green light, or laser pointers of other colors, they must be used with caution and cannot be used to irradiate the human body, otherwise it may cause harm to the human body.

Key differences:
1. The light-emitting principle is different.
The red laser pointer mainly relies on red laser diodes to emit light, and its structure is the simplest, and only one battery can be used as an energy source. The green laser pointer uses a wavelength of 808nm infrared laser to excite a nonlinear crystal as a light source, it can generate 1064nm infrared light, and then frequency double to generate 532nm green light, which belongs to solid laser.
2. Different scope of use
Green laser pointers are used in a wider range. At night, even low-power green light can be seen due to the Rayleigh scattering of atmospheric molecules, but the effect of red light is much worse. Both green and red laser pointers can be used for e-learning and presentations, but green laser pointers can be used to point to stars and constellations, but green laser pointer are not.
