Pākēka muahāmeʻa laser attosecondke kūkulu ʻia nei

Ua lilo ka attosecond i mea hana hou no nā mea noiʻi e ʻimi i ke ao uila. "No nā mea noiʻi, he mea pono ka noiʻi attosecond, me ka attosecond, e ʻoi aku ka maopopo o nā hoʻokolohua ʻepekema he nui i ke kaʻina hana dynamics unahi atomika pili, e ʻoi aku ka pololei o nā kānaka no nā protein biological, nā hanana ola, ka unahi atomika a me nā noiʻi pili ʻē aʻe." wahi a Pan Yiming.

Manaʻo ʻo Wei Zhiyi, he mea noiʻi ma ka Institute of Physics o ka Chinese Academy of Sciences, ʻo ka holomua o nā pulse māmā coherent mai femtoseconds a i attoseconds ʻaʻole wale ia he holomua maʻalahi i ka pae manawa, akā ʻoi aku ka nui, ʻo ka hiki i nā kānaka ke aʻo i 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, ka mea i hoʻoulu ai i kahi kipi nui i ka noiʻi physics kumu. ʻO ia kekahi o nā pahuhopu ʻepekema koʻikoʻi a ka poʻe e alualu ai e ana pololei i ka neʻe ʻana o nā electrons, e hoʻomaopopo i ka hoʻomaopopo ʻana i ko lākou mau waiwai kino, a laila e kāohi i ka ʻano hana o nā electrons i loko o nā ʻātoma. Me nā pulse attosecond, hiki iā mākou ke ana a hoʻoponopono i nā ʻāpana microscopic pākahi, a pēlā e hana ai i nā nānā a me nā wehewehe kumu a me nā kumu o ka honua microscopic, kahi honua i hoʻomalu ʻia e nā mechanics quantum.

ʻOiai ua mamao iki kēia noiʻi mai ka lehulehu, ʻo ka hoʻoulu ʻana o nā "ʻēheu pulelehua" e alakaʻi maoli i ka hōʻea ʻana mai o ka noiʻi ʻepekema "ʻino". Ma Kina, attosecondlaserUa hoʻokomo ʻia nā noiʻi pili i ke kuhikuhi hoʻomohala koʻikoʻi o ka ʻāina, ua kūkulu ʻia ka ʻōnaehana hoʻokolohua pili a ke hoʻolālā ʻia nei ka mea ʻepekema, e hāʻawi i kahi ala hou koʻikoʻi no ke aʻo ʻana i ka dynamics attosecond, ma o ka nānā ʻana i ka neʻe ʻana o ka electron, e lilo i "microscope electron" maikaʻi loa i ka māhele hoʻonā manawa e hiki mai ana.

Wahi a ka ʻike lehulehu, he attosecondhāmeʻa laserKe hoʻolālā ʻia nei ma ka Songshan Lake Materials Laboratory ma ka ʻĀpana ʻo Guangdong-Hong Kong-Macao Greater Bay ma Kina. Wahi a nā hōʻike, ua kūkulu pū ʻia ka hale hana laser attosecond holomua e ka Institute of Physics of the Chinese Academy of Sciences a me ka Xiguang Institute of the Chinese Academy of Sciences, a ua komo ka Songshan Lake Materials Laboratory i ke kūkulu ʻana. Ma o ka hoʻolālā hoʻomaka kiʻekiʻe, ʻo ke kūkulu ʻana i kahi kikowaena laina multi-beam me ke alapine hana hou 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 pulse pōkole loa ma lalo o 60as a me ka ikehu photon kiʻekiʻe loa a hiki i 500ev, a ua lako me ka paepae noiʻi noi like, a ke manaʻo ʻia nei e hoʻokō ka papa kuhikuhi piha i ke alakaʻi honua ma hope o ka pau ʻana.
