The PEARL (PEtawatt pARametric Laser) which was built in 2006 at the Institute of Applied Physics (IAP) of the Russian Academy of Sciences (RAS), makes it possible to create the most powerful light radiation on Earth. This setting is based on the technology of parametric amplification of light in nonlinear optical crystals, and can provide the spark for 0.56 petawatts of power, significantly greater than the capacity of all existing power plants. There are also plans to launch the XCELS project, which involves creating laser power up to 200 petawatts, and later up to 1 exawatt. According to physicist Efim Khazanov, such laser systems will explore extreme physical processes and the fundamental laws of the universe. The electric field in the light pulse exceeds the field holding the electron near the nucleus by several degrees,” he says. “The radiation intensity can reach values at which the vacuum could produce matter and antimatter.” The existing facilities’ main function is to research exawatt lasers. However, if the results of the work are able to enter the planning phase, the range of applications for these lasers could expand, Khazanov explains. This could make the treatment of cancerous tumors significantly cheaper and less harmful than X-ray treatments,” he said. Acum astept injuraturi cu rusii!
