Ke kūkulu ʻia nei ka mīkini laser attosecond mua o Kina

ʻO Kina ka muamea laser attosecondke kukuluia nei

Ua lilo ka attosecond i mea hana hou no nā mea noiʻi e ʻimi i ka honua uila."No ka poʻe noiʻi, pono ka noiʻi attosecond, me ka attosecond, ʻoi aku ka maopopo o nā hoʻokolohua ʻepekema i ke kaʻina hana hoʻoikaika atomika pili, ʻoi aku ka pololei o ka poʻe no nā protein olaola, nā hanana ola, ka unahi atom a me nā noiʻi ʻē aʻe e pili ana."Ua ʻōlelo ʻo Pan Yiming.

ʻO Wei Zhiyi, he mea noiʻi ma ka Institute of Physics of the Chinese Academy of Sciences, manaʻoʻiʻo ʻo ka holomua o nā pulses kukui coherent mai nā femtoseconds a i attoseconds ʻaʻole ia he holomua maʻalahi i ka pae manawa, akā ʻoi aku ka mea nui, ʻo ka hiki o nā kānaka ke aʻo. ʻO ke ʻano o ka mea, mai ka neʻe ʻana o nā ʻātoma a me nā molekala i loko o nā ʻātoma, hiki ke ʻike i ka neʻe ʻana o nā electrons a me nā ʻano pili e pili ana, kahi i hoʻoulu ai i kahi hoʻololi nui i ka noiʻi physics kumu.ʻO ia kekahi o nā pahuhopu ʻepekema koʻikoʻi a ka poʻe e ʻimi nei e ana pono i ka neʻe o nā electrons, ʻike i ka hoʻomaopopo ʻana i ko lākou mau waiwai kino, a laila hoʻomalu i ka ʻano ikaika o nā electrons i nā mana.Me nā pulses attosecond, hiki iā mākou ke ana a me ka hoʻoponopono ʻana i nā ʻāpana microscopic pākahi, a pēlā e hana ai i nā ʻike kumu a me nā wehewehe kumu o ka honua microscopic, kahi honua i hoʻomalu ʻia e ka quantum mechanics.
ʻOiai ua mamao iki kēia noiʻi mai ka lehulehu, ʻo ka hoʻoulu ʻana o "nā ʻēheu butterfly" e alakaʻi maoli i ka hōʻea ʻana o ka noiʻi ʻepekema "ʻino".Ma Kina, attosecondlaserua hoʻokomo ʻia ka noiʻi pili i loko o ka ʻaoʻao hoʻomohala koʻikoʻi o ka ʻāina, ua kūkulu ʻia ka ʻōnaehana hoʻokolohua kūpono a ke hoʻolālā ʻia nei ka mea ʻepekema, e hāʻawi i kahi ala koʻikoʻi no ke aʻo ʻana i nā dynamics attosecond, ma o ka nānā ʻana i ka neʻe electron, lilo i mea maikaʻi loa. "microscope electron" i ka mahele hoʻonā manawa e hiki mai ana.

Wahi a ka ʻike lehulehu, he attosecondmea laserke hoʻolālā ʻia nei ma ka Songshan Lake Materials Laboratory ma Kina Guangdong-Hong Kong-Macao Greater Bay Area.Wahi a nā hōʻike, ua kūkulu pū ʻia ka hale hana laser attosecond kiʻekiʻe e ka Institute of Physics o ka Chinese Academy of Science a me ka Xiguang Institute o ka Chinese Academy of Science, a ua komo ka Songshan Lake Materials Laboratory i ke kūkulu ʻana.Ma o ka hoʻolālā kiʻekiʻe o ka hoʻomaka ʻana, ʻo ke kūkulu ʻia ʻana o kahi laina laina multi-beam me ke alapine repetition kiʻekiʻe, ka ikehu photon kiʻekiʻe, ke kahe kiʻekiʻe a me ka laulā puʻupuʻu pōkole loa e hāʻawi i ka radiation coherent ultrafine me ka laulā puʻupuʻu pōkole loa ma lalo o 60as a me ka ikehu photon kiʻekiʻe. i 500ev, a ua lako me ka noiʻi noiʻi anuu pili, a me ka papa kuhikuhiE kuhikuhipuʻuone ua manaoia e hoʻokō i ka honua alakaʻi ma hope o ka pau ana.
