That shift reduced the pulse duration of high-energy lasers from around 500 femtoseconds (fs) to around 25 fs.<\/p>\n<p>However, the <a href=\"https:\/\/phys.org\/tags\/upper+limit\/\" rel=\"tag\" class=\"\">upper limit<\/a> for titanium: sapphire ultra-intense ultrashort lasers appears to be 10-petawatt. Presently, for 10-petawatt to 100-petawatt development planning, researchers generally abandon the titanium: sapphire chirped pulse <a href=\"https:\/\/phys.org\/tags\/amplification\/\" rel=\"tag\" class=\"\">amplification<\/a> technology, and turn to optical parametric chirped pulse amplification technology, based on deuterated potassium dihydrogen phosphate nonlinear crystals. That technology, due to its low pump-to-signal conversion efficiency and poor spatiotemporal-spectral-energy stability, will pose a great challenge for the realization and application of the future 10\u2013100 petawatt lasers.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ultra-intense ultrashort lasers have a wide-ranging scope of applications, encompassing basic physics, national security, industrial service, and health care.
