Laser Is The Most Widely Used Green Laser Pointer
For the first time, scientists have used topological photonics to create a green laser pointer beam. It has always been the unremitting pursuit of scientists to emit lasers more effectively. The latest research opens up completely new research ideas. Lasers, atomic energy, semiconductors, and computers are regarded as four modern inventions of the 20th century. Laser technology is a technology that uses strong energy such as light or electrical discharge to excite a specific substance to produce light. It is used in many fields such as machinery, aviation, electronics. Currently. Fiber laser is the most widely used green laser pointer.

According to forecasts. Global optical fiber green laser pointer sales will increase from US $ 1.59 billion in 2017 to US $ 2.5 billion in 2020. The compound annual growth rate is 16.28%. With the rapid development of lasers, correspondingly, research on laser technology in various countries has never stopped. In the latest research, a team from the Haifa Institute in Israel created a laser beam based on topological photonics. And the light waves in them are in phase. This means that the energy loss of the technology will be lower. That is, green laser pointers have higher emission efficiency.Lasers are used for a variety of purposes, including pointing out objects during demonstrations, alighting materials on construction sites and in homes, and for doctors performing cosmetic and surgical procedures. Many objects you encounter every day use lasers, including CD and DVD players; Barcode scanner; The drill. Laser guidance tools, such as a level; And laser Pointers. Some lasers emit radiation in the form of light. Others emit invisible radiation, such as ultraviolet or infrared radiation. In general, laser radiation is harmless in itself and behaves very much like ordinary light in its interactions with the body. Laser radiation should not be confused with radio waves, microwaves, ionizing X-rays, or radiation from radioactive substances such as radium.
