In a study recently published in <i>Scientific Reports<\/i>, researchers from Osaka University proposed a concept for next-generation ultra-intense lasers with a simulated peak power up to the Exawatt class (1 Exawatt equals 1000 Petawatts).<\/p>\n<p>The laser, which was invented by Dr. T. H. Maiman in 1960, has one important characteristic of high intensity (or high peak power for pulse lasers): historically, laser peak power has experienced two-stage development. Just after the birth of the laser, Q-switching and mode-locking technologies increased laser peak power to Kilowatt (10<sup>3<\/sup> Watt) and Gigawatt (10<sup>9<\/sup> Watt) levels. After CPA technology was invented by G\u00e9rard Mourou and Donna Strickland in 1985, by which material damage and optical nonlinearity were avoided, laser peak power was dramatically increased to Terawatt (10<sup>12<\/sup> Watt) and Petawatt (10<sup>15<\/sup> Watt) levels. Today, two 10-Petawatt CPA lasers have been demonstrated in Europe (ELI-NP laser) and China (SULF laser), respectively.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers from the Max Planck Society assessed humans\u2019 capabilities for controlling killer AI.
