ʻO nā ʻenehana a me nā ʻano hoʻomohala o nā lasers attosecond ma Kina

Nā ʻano hana ʻenehana a me ka hoʻomohala ʻana onā lasers attosecondma Kina

Ua hōʻike ka Institute of Physics, Chinese Academy of Sciences, i nā hopena ana o 160 ma ke ʻano he mau pulse attosecond i hoʻokaʻawale ʻia i ka makahiki 2013. Ua hoʻokumu ʻia nā pulse attosecond i hoʻokaʻawale ʻia (IAPs) o kēia hui noiʻi ma muli o nā harmonics kiʻekiʻe i hoʻokele ʻia e nā pulse laser femtosecond sub-5 i hoʻopaʻa ʻia e CEP, me ka helu hana hou o 1 kHz. Ua hōʻike ʻia nā ʻano manawa o nā pulse attosecond e ka spectroscopy hoʻolōʻihi attosecond. Hōʻike nā hopena hiki i kēia beamline ke hāʻawi i nā pulse attosecond i hoʻokaʻawale ʻia me ka lōʻihi o ka pulse o 160 attoseconds a me ka nalu waena o 82eV. Ua hana ka hui i nā holomua i ka hanauna kumu attosecond a me ka ʻenehana spectroscopy hoʻolōʻihi attosecond. ʻO nā kumu kukui ultraviolet koʻikoʻi me ka hoʻonā attosecond e wehe pū i nā kahua noi hou no ka physics mea condensed. I ka makahiki 2018, ua hōʻike pū ka Institute of Physics, Chinese Academy of Sciences, i kahi hoʻolālā kūkulu no kahi mea hoʻohana ana i hoʻoholo ʻia i ka manawa wikiwiki e hoʻohui i nā kumu kukui attosecond me nā kikowaena ana like ʻole. E hiki ai i kēia i nā mea noiʻi ke hana i nā ana hoʻonā manawa attosecond a femtosecond o nā kaʻina hana ultrafast i loko o ka mea, me ka loaʻa ʻana o ka momentum a me ka hoʻonā spatial. A hiki iā ia i nā mea noiʻi ke ʻimi a kāohi i ka dynamics uila ultrafast microscopic i loko o nā ʻātoma, nā molekala, nā ʻili a me nā mea paʻa nui. ʻO kēia ka mea e hoʻomākaukau ai i ke ala no ka hoʻomaopopo ʻana a me ka hoʻopili ʻana i nā hanana macroscopic pili e uhi ana i nā ʻano noiʻi he nui e like me ka physics, kemika a me ka biology.

I ka makahiki 2020, ua hāpai ke Kulanui ʻEpekema a me ka ʻenehana ʻo Huazhong i ka hoʻohana ʻana i kahi ala ʻōpiki āpau e ana pololei a hana hou i nā pulse attosecond ma o ka ʻenehana gating optical i hoʻoholo pinepine ʻia. I ka makahiki 2020, ua hōʻike pū ka Chinese Academy of Sciences ua hoʻopuka pono ʻo ia i nā pulse attosecond i hoʻokaʻawale ʻia ma ke ʻano o ke kahua photoelectric pulse femtosecond ma o ka hoʻohana ʻana i ka ʻenehana pass-gate koho dual-light. I ka makahiki 2023, ua hāpai kahi hui mai ke Kulanui ʻEpekema Palekana o ke Aupuni i kahi kaʻina hana PROOF wikiwiki, i kapa ʻia ʻo qPROOF, no ke ʻano o nā pulse attosecond i hoʻokaʻawale ʻia me ka ultra-wideband.

I ka makahiki 2025, ua hoʻomohala nā mea noiʻi mai ka Chinese Academy of Sciences ma Shanghailaserʻenehana hoʻonohonoho like e pili ana i kahi ʻōnaehana hoʻonohonoho like manawa i kūkulu kūʻokoʻa ʻia, e hiki ai ke ana ʻana i ka jitter manawa kiʻekiʻe a me ka pane manawa maoli o nā lasers picosecond. ʻAʻole wale kēia i kāohi i ka jitter manawa o ka ʻōnaehana i loko o ka pae attosecond akā ua hoʻonui pū i ka hilinaʻi o kaʻōnaehana laseri ka wā hana lōʻihi. Hiki i ka ʻōnaehana loiloi a me ka hoʻomalu i hoʻomohala ʻia ke hana i ka hoʻoponopono manawa maoli no ka jitter manawa. I ka makahiki hoʻokahi, ua hoʻohana pū nā mea noiʻi i nā lasers relativistic intensity spacetime vortices (STOV) e hana i nā pulse gamma-ray attosecond i hoʻokaʻawale ʻia e lawe ana i ka momentum angular orbital lateral.

Aia ke kahua o nā lasers attosecond i kahi manawa o ka hoʻomohala wikiwiki ʻana, e uhi ana i nā ʻano he nui mai ka noiʻi kumu a hiki i ka hoʻolaha noi. Ma o nā hana a nā hui noiʻi ʻepekema, ke kūkulu ʻana i nā ʻoihana, ke kākoʻo ʻana i nā kulekele aupuni, a me ka laulima kūloko a me ka honua a me nā hoʻololi, e hauʻoli ka hoʻolālā ʻana o Kina ma ke kahua o nā lasers attosecond i nā manaʻolana hoʻomohala ākea. I ka hui pū ʻana o nā kulanui a me nā ʻoihana noiʻi i ka noiʻi ʻana ma nā lasers attosecond, e hoʻoulu ʻia kahi hui o nā talena noiʻi ʻepekema me kahi hiʻohiʻona honua a me nā hiki hou, e paipai ana i ka hoʻomohala mau ʻana o ka ʻepekema attosecond. E hāʻawi pū ka hale ʻepekema nui ʻo National Attosecond i kahi kahua noiʻi alakaʻi no ke kaiāulu ʻepekema a hāʻawi i nā hāʻawi nui i ka holomua o ka ʻepekema a me ka ʻenehana.
