What is the price of the 3000mw green indicator?
Some 3000mw green laser pointers work in pulse or quasi-continuous operation to reduce cooling problems and extend battery life. Even at night, air molecules can see the laser pointer-strong green Rayleigh scattering. This laser pointer is often used for astronomy enthusiasts who display stars and constellations. Green lasers can have a variety of output powers. Since the wavelength of the laser module produces red, the structure is the simplest, basically just made of a battery-powered diode. The red laser module first appeared in the 1980s. It is a huge device worth hundreds of dollars. It is now small and cheap. In recent years, a diode-pumped solid-state laser (DPSS) high power laser pointer with a wavelength of 671nm has appeared. Although this wavelength can be obtained with inexpensive diodes, DPSS technology can produce higher-quality, narrower-band lasers. Most of the current green, red, and blue laser pointers are small in size, but expensive. The 50mw green laser pointer is relatively easy to make, with a wavelength of about 532 nanometers, mature technology, and precise semiconductor process materials. The wavelength of the red laser is also 600 nanometers. This is because the current ribbon semiconductor laser technology is not very mature, so the red laser pointer is expensive and low in power.

If the laser pointer you are using can be seen from hundreds of meters away, please use the laser pointer frequently. Most of the current green, red, and blue laser pointers are small in size, but expensive. The 50mw green laser pointer is relatively easy to make, with a wavelength of about 532 nanometers, mature technology, and precise semiconductor process materials. The wavelength of the red laser is also 600 nanometers. This is because the current ribbon semiconductor laser technology is not very mature, so the red laser pointer is expensive and low in power. The super laser pointer can set off fireworks, making it easier to burn balloons. After buying a "strong laser" online, a set of comparative experiments found that the laser pointer cigarette claims. Moreover, if the laser pointer beam does not pay attention to the surface of the human skin, it will produce a burning sensation. Obviously, the laser pointer is not suitable as a "toy". Sent with 5000mw laser pointer and a box of matches. Unlike ordinary games, the head of this box of matches is black. The seller told reporters that because black is easy to absorb heat, this gaming black laser pointer is easy to light up.

Nowadays, the 1000mw laser pointer is becoming more and more popular among students, but some students pass the laser pointer back and forth through the eyes of the students. Experts suggest that when the laser pointer is used to irradiate the eyes directly, it is easy to damage the eyes and even cause permanent blindness.
