The use of lasers is very wide. Especially high-energy laser pointer have huge application potential in the fields of cancer treatment and particle physics. The development of high-energy lasers in Japan. Tokyo. The world is planning to create extremely high-energy lasers. Because high-energy lasers can make the cost of X-ray observers and equipment for treating malignant tumors through proton beams lower. They will become a reality to a large extent.
In Japan, the National Institute of Quantum and Radiology Science and Technology, established in April this year, has become an important institution in the field of high-energy lasers in Japan. The Japanese cabinet also decided to make lasers an important research and development topic. A professor at Osaka University in Japan said: “Europe, the United States, South Korea and China have all started the development of high-power lasers.
If Japan does not start to develop high-performance lasers now, it will not be able to keep up with the global rhythm within a few years. I believe most people are familiar with lasers. Blue type lasers are used to read and write Blu-ray discs, while red ones are often used as laser pointers in presentations. High-energy lasers emit an order of magnitude stronger light than ordinary beams, and they are also the focus of competition in the international laser field.
The power of a laser is often expressed in watts per square centimeter. Imagine that the sun’s rays are focused to a point with a diameter of 0.1 mm through a huge lens the size of the earth’s diameter. The result will be 1,000 trillion times of 1 million watts of energy. The world’s most powerful green laser pointer was built in 2008 at the University of Michigan, and its power is 10 times as much. But this intensity cannot be maintained for too long, only 30 quadrillionths of a second.
The smaller the size, the greater the power. Compared with the applications in people’s daily life, the applications of high-energy lasers are more peculiar. Scientists are currently trying to uncover the secrets of this microscopic world by sending protons and electrons through linear and ring-shaped giant magnets. This method requires a large and expensive particle accelerator. But high-energy lasers can do this. In theory, the cost is lower and the space required is smaller.
