1

At present, due to the needs of actual industrial production. Advances in green laser pointer positioning technology worldwide. Laser locators are moving in a higher direction. Such as higher accuracy, faster and convenient use, small size and easy to carry, and so on. The entire laser ranging field is also making continuous progress in this direction. However, the current laser ranging and positioning technology is still immature in the development of technology, and the gap with Western European and American countries is very obvious. Some high-precision green laser pointers ranging and positioning products still need to be imported from abroad. And the price is also very expensive.

Particles move very fast. It has always been difficult for humans to see exactly how they move. The hard X-ray free electron green laser pointer device solves this problem. "This device is similar to a 'high-speed ultra-high-definition camera', which can 'make a movie' for molecules, atoms, and electrons, and capture instantaneous moving images of the microscopic world with high resolution in femtosecond scale time. Clarify the detailed process of complex chemical reactions, "said Zhu Zhiyuan, secretary of the Party Committee of Shanghai University of Science and Technology and general manager of the hard X-ray free electron laser device project. Taking energy research as an example, Yang Peidong, the founding dean of the School of Material Science at Shanghai University of Science and Technology, believes that the device can help scientists see the specific reaction process of photosynthesis in nature. Based on this, a green laser pointer artificially synthesized new material can be simulated and developed. Greatly eliminate the harm of the greenhouse effect on humans.

Therefore, since we know that we need at least 100 megawatts of power, and the higher the power, the better the combustion performance, so we need to study different types of lasers. Generally speaking, AAA battery-powered pen or keychain lasers are almost never regarded as burning lasers. If this pen is powered by AAA batteries, it may not be a high-power combustion laser. You can simply use it intermittently through the buttons on the body. You do need to hold down the button, but for this short-term switch, this may be your best choice.
 
Many of them are low power, about 5 megawatts, which means they will be visible and useful, but they will not be able to light matches or burst balloons. Large batteries using rechargeable batteries constitute almost all lasers that are classified as burning. Therefore, be sure to check the main body and battery of any unit. This will depend on the laser you plan to use. If you want to use the laser pointer to point out the content on the classroom blackboard or projector, the simple AAA laser pointer style may be the best choice.
