Ke kūkulu ʻia nei ka mīkini laser attosecond mua Kina

Pākēka muamea laser atosecondke 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 dynamics unahi atomika kūpono, ʻoi aku ka pololei o nā kānaka no nā protein biological, 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 Science, 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, ka hiki o nā kānaka ke aʻo. ʻO ke ʻano o ka mea, mai ka neʻe ʻana o nā ʻātoma a me nā molekala a i loko o nā ʻātoma, hiki ke ʻike i ka neʻe ʻana o nā electrons a me nā ʻano pili, i hoʻoulu ai i kahi kipi nui i ka noiʻi physics. 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 hoʻoponopono 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, ka flux kiʻekiʻe a me ka laulā pulse 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, a me ka huina hoonui i manaoia e hoʻokō i ka honua alakaʻi ma hope o ka pau ana.
