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 ʻana 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 i ke ʻano o ka mea, mai ka neʻe ʻana o nā atoms a me nā molekole i loko o nā ʻātoma, hiki ke ʻike i ka neʻe ʻana o nā mea uila. noiʻi. 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, attosecondlaserpili noiʻi ua komo i loko o ka 'āina koʻikoʻi hoʻomohala kuhikuhi, ua kūkulu ʻia ka ʻōnaehana hoʻokolohua kūpono a ke hoʻolālā ʻia nei ka mea ʻepekema, e hāʻawi i kahi ʻano mea hou nui no ke aʻo ʻana i ka dynamics attosecond, ma o ka nānā ʻana i ka neʻe electron, e lilo i "microscope electron" maikaʻi loa i ka ʻāpana 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 hoʻomaka kiʻekiʻe, 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 puʻupuʻu pōkole loa e hāʻawi ai 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 ʻia me ka papa noiʻi noiʻi e pili ana, a ua manaʻo ʻia ka alakaʻi piha ma hope o ka hoʻokō ʻana i ka honua.
