U.S. develops world's largest power laser to be used in cancer treatment

scientists at the University of Michigan laboratory in the United States recently developed a laser beam, which is two orders of magnitude stronger than other existing lasers in the world, a strong beam of light can be widely used in the field of radiation therapy cancer, greatly contributing to the development of proton therapy and electronic therapy technologyThe findings were published online in the journal Optical LettersScientists added amplifiers to Hercules laser systems to make a new laser beamHercules is a titanium-mixed sapphire laser that occupies several rooms in the lab and, once light feedback enters the system, is emitted between continuous mirrors and optics, which is the process of energy focusingHercules previously had a maximum output of 50 terawatts, and the laser beam with the amplifier added can reach 300 terawatts, about 300 times the output power of all Power Stations in the United StatesThe measurements show that the laser's strength can reach 2 x 1022 watts per square centimeter, and its instantaneous energy is equivalent to concentrating the sun's beam on the Earth into one gravel with a huge magnifying glassThe laser's launch time is only 30 femtoseconds, but it is extremely short but can concentrate energy at a point of 1.3 microns, which is equivalent to one percent of the diameter of a human hairAnother new technology is that the laser can emit energy every 10 seconds, while other lasers take an hour to rechargeThe power and adaptability of the new laser makes it more widely used and more accessible to cutting-edge technologies other than medicalFor example, an extremely strong laser beam can reach the point where the vacuum is boiled, and the beam can only be focused when the experiment is neededScientists have also noted the role of new laser beams in inertial constrained fusion studiesThe technology has been stuck on individual devices since scientists came up with the idea of laser-induced fusion in the 1960sLaser energy, which can be achieved on a practical scale, is unthinkable, at the time or in the decades that followed, and the new laser beam gives scientists a sense of feasibility(Zhang Mengran)
