Muyeso wa m'lifupi mwa laser
Kuyeza m'lifupi mwa mzere wa laser Pali njira zambiri zoyezera m'lifupi mwa mzere wa laser: 1. Pamene m'lifupi mwa mzere wa laser ndi waukulu (> 10 GHz, pamene njira zingapo zimasinthasintha mu ma resonator angapo a laser), ma spectrometer achikhalidwe omwe amagwiritsa ntchito ma diffraction gratings angagwiritsidwe ntchito poyeza. Komabe, njira iyi...Werengani zambiri -
Laser yofulumira kwambiri ya sayansi ya attosecond
Laser yofulumira kwambiri ya sayansi ya attosecond Pakadali pano, ma attosecond pulses amapezeka makamaka kudzera mu kupanga kwa harmonic yapamwamba (HHG) yoyendetsedwa ndi minda yolimba. Kupangidwa kwawo kumatha kumveka ngati ma electron omwe amasinthidwa kukhala ion, kufulumizitsidwa, ndikugwirizanitsidwanso ndi magetsi amphamvu a laser...Werengani zambiri -
