Laser pointers play a major role in the Tokyo Olympics

As we all know, the laser pointer is a tool that plays a major role in our work and daily life, but in addition to being often used in meetings to help with presentations, it also has a very important role outside the meeting room. In the Tokyo Olympics, the laser pointer played a major role. With its high unidirectionality and long-distance pointing function, the high power laser pointer can point out the direction to the athletes in the Tokyo Olympics and keep the scene from being chaotic.

The laser pointer can also be used as a demonstration

You've probably seen a laser show, colorful lasers can create a great stage atmosphere, and generally speaking, AAA battery-powered pen or keychain lasers are almost never considered burning lasers. Many of them are low power, around 5 megawatts, which means they will be visible and useful, but not able to light a match or pop a balloon. Large batteries that use rechargeable batteries make up nearly all green laser pointer that are classified as burning. European XFEL displays and captures images. Subatomic secrecy drives breakthroughs in medicine, biology, energy, information technology and chemistry. List the molecular structures of viruses and cells. Send nanoscale 3D snapshots. And the chemistry as the movie unfolds. Geoscientists should be able to replicate and study the processes that take place deep within the Earth, including ourselves. "The laser is the largest and most powerful source of X-rays ever built," Olivier Napoli, a member of the French Atomic Energy Commission who helped build the complex, told AFP.
