Creating 'ghostly mirrors' for high-power lasers

https://phys.org/news/2023-01-ghostly-mirrors-high-power-lasers.html

"small footprint, ultra-high-power, ultra-short pulse laser... from hundreds of petawatts to exawatts... reduce size of ultra-high power lasers, which currently occupy buildings the size of aircraft hangars, to single room, table top, for reasonable price... mirror exists only fleetingly, for a few picoseconds... Plasma can withstand intensities up to 1018 watts per square cm, exceeding threshold for damage of conventional optics by four or five orders of magnitude, shrinking meter-sized optics to mm or cm"
