Reaching extreme light intensities by utilizing electrons' collective motion in a plasma, bypassing chirped pulse amplification limitations

https://www.eurekalert.org/news-releases/1124675 "high laser intensity breaks optical gratings/ mirrors, so made larger, but expensive/ difficult... overcome using ionized atom plasma (unbreakable) as amplifying medium... interference pattern organizes plasma into dense layers acting like highly efficient, transient mirror reflecting energy from pump beam into seed beam, compressing into light intensities orders magnitude higher reaching Schwinger limit (intense enough to create matter/ antimatter directly out of vacuum)... tabletop particle accelerators, photonics"
