most powerful personal laser

For the safety of laser products, the country has a clear standard. But reporters found that some online sales of laser pen manufacturer’s name is not clearly marked and graded, as the red laser pointer may cause harm to the human body is mentioned.

In addition, net sales of laser pointer, although some indicated graded, but not suitable for tour guides, point to the exhibition use. Reporters noted that some net sales of laser pointer that says “Class 1 laser product”, which is a Class 1 laser products, and some products are marked “3A” class or “3B” category, very few still marked ” 4B “. According to GB7247 standard laser safety requirements for radiation protection, Class 1, Class 2, 3A class laser is weak laser, 3B, 4 Laser class. GB document recommends the use of more than one Class 3A laser device, “should appoint a laser safety officer” and in need of the occasion, especially for Class 4 laser product users provide protective clothing and goggles. Visible, laser pointer has been far beyond the scope of toys.

“When using the green laser pointer, do not let the laser beam direct exposure to the eye.” Professor Yang said that because of this damage is irreversible, especially in such a high power laser pointer, but not to the children to play, to avoid unnecessary hurt.

Excitation wavelength of 808nm infrared laser nonlinear crystal to generate 1064nm infrared light, and then the frequency doubling 532nm green, is a solid laser. Some green lasers pointers operate in pulse or quasi-continuous mode down to reduce cooling problems and prolong battery life. Announced undesired harmonic green laser light has a higher efficiency. Even at night, low-power green Rayleigh scattering due to atmospheric molecules can also see that this laser pointer is often used for astronomy lovers pointing stars and constellations. Green Laser Pointer can have a variety of output power. 5mW to use the safest, and can also be found in dark lighting, so no need for the guidance of the purpose of a stronger power.

In crowded public places, in order to avoid accidental injury to others, you should stop using the laser pointer. Some high power laser pointer will be significant thermal effect, can not long continuous use, especially for temperature sensitive solid-state laser.
