How can I buy a suitable laser pen?
People will find that the green high powered laser pointer between 1MW and 5MW is not bright enough and is invisible in astronomy. The light beam will become dark and gloomy in the sky. On the contrary, high-power laser may damage the retina and lead to serious aviation accidents. 5MW to 50MW medium power green laser pen is enough and is very suitable for star standard. Visible light beams can pass through the earth's atmosphere and reach the target object quickly. You will be able to see the celestial bodies clearly and accurately.
With the development of semiconductor chip technology and optical technology, the output power of semiconductor laser is continuously improved, the beam quality is significantly improved, and many applications have been obtained in the industrial field. At present, the output power and beam quality of high-power industrial semiconductor lasers have exceeded pump lamp YAG lasers and are close to semiconductor YAG lasers. Semiconductor lasers have been gradually applied in plastic welding, cladding and alloying, surface heat treatment, metal welding and other fields, and progress has been made in marking and cutting.

Laser has been a controversial topic since its inception. Everyone pays close attention to the danger of laser and the safety of its operation. Laser danger is not as terrible as we think, as long as we have a general understanding of laser safety knowledge. Jetlasers aims to provide useful instructions on laser safety and hazards without exaggeration.Laser has been a controversial topic since its inception.

Laser danger is not as terrible as we think, as long as we have a general understanding of laser safety knowledge. Jetlasers aims to provide useful instructions on laser safety and hazards without exaggeration. The blue laser indicator is usually generated by frequency doubling 946 nm laser radiation from diode pumped Nd: YAG or Nd: YVO4 crystals. At the same time, there are 450nm blue laser pens on the open market, which are produced by finished 450nm laser diodes. The low power 460nm blue laser can also be used as a demonstration tool under various conditions.
