Definition of bright laser pointer
Generally, a higher power laser will make a longer beam visible and better scatter the beam, allowing you to choose a more powerful laser pointer to point at the stars and other constellations, while sharing the beautiful night view. The super-powered laser pointer has always been a wonderful entertainment product. For example, you will enjoy bursting balloons, burning plastic and rubber, lighting matches, and cutting tape with a more powerful laser pointer. The laser can work continuously at a clearly defined frequency and wavelength, and the accuracy is better than the parts in 10 16. This allows the laser to provide standards for time and length scales. It provides a spectrally pure light source that can be tuned to very narrow resonances in atoms and molecules, coupled so tightly that it can very precisely manipulate the internal states of atoms and molecules and allow them to move. The heat is so slow that their temperature can be reduced from absolute zero to a fraction of a degree.

With the development of high powered laser, laser pointers are often convenient for people. People use the long-distance pointing characteristics of the laser pointer. In many natural disasters, their lights are used as guides and distress signals. In a dim environment, you can clearly see the lines of this beam, which has become an important guiding tool. Not only that, it began to gradually integrate into people's presentations, combined with our computers, produced a new type of laser pointer page presentation laser pointer. Its creation helps presenters, especially teachers' presentations. When I was in school, I often saw teachers dancing with a pen-like tool in their hands. When the teacher presses the corresponding function key on the laser pointer, the classroom ppt can be rotated and used. As an important display tool, it can help the listener clearly understand the current location.
