Iyo tekinoroji uye maitiro ekusimudzira eattosecond lasers muChina
The Institute of Physics, Chinese Academy of Sciences, yakashuma kuyerwa kwemigumisiro ye160 seyakasarudzika attosecond pulses muna 2013. The isolated attosecond pulses (IAPs) yeboka iri rekutsvakurudza yakagadzirwa maererano nepamusoro-soro harmonics inotungamirirwa ne-sub-5 femtosecond laser pulses yakagadzikana neCEP repetiH. Hunhu hwenguva dzeatosecond pulses hwairatidzwa neattosecond stretch spectroscopy. Mhedzisiro yacho inoratidza kuti beamline iyi inogona kupa yakasarudzika attosecond pulses ine pulse duration ye160 attoseconds uye yepakati wavelength ye82eV. Chikwata chakaita budiriro muatosecond sosi chizvarwa uye attosecond inotambanudza spectroscopy tekinoroji. Yakanyanya ultraviolet mwenje masosi ane attosecond resolution ichavhurawo minda mitsva yekushandisa yeyakapfupikiswa nyaya fizikisi. Muna 2018, iyo Institute of Physics, Chinese Academy of Sciences, yakashumawo chirongwa chekuvaka chemuchinjika-chirango chekupedzisira-chakagadziriswa cheyero mushandisi mudziyo unosanganisa attosecond magetsi masosi ane akasiyana kuyerwa zviteshi. Izvi zvinogonesa vaongorori kuitisa anochinjika attosecond kune femtosecond-yakagadziriswa zviyero zve Ultrafast process in matter, ukuwo vaine kukurumidza uye kugadzirisa kwenzvimbo. Uye inobvumira vaongorori kuti vaongorore uye vadzore iyo microscopic ultrafast electronic dynamics mumaatomu, mamorekuru, nzvimbo uye zvinhu zvakawanda zvakasimba. Izvi zvinozopedzisira zvagadzira nzira yekunzwisisa uye nekushandisa yakakodzera macroscopic zviitiko zvinofukidza akawanda ekutsvagisa maitiro akadai sefizikisi, chemistry uye biology.
Muna 2020, Huazhong University yeSainzi neTekinoroji yakakurudzira kushandiswa kwenzira yekuona-yese kuyera uye kuvakazve mapurusi eatosecond kuburikidza neiyo frequency-yakagadziriswa optical geting tekinoroji. Muna 2020, iyo Chinese Academy yeSainzi yakashuma zvakare kuti yakabudirira kugadzira ega attosecond pulses nekugadzira femtosecond pulse photoelectric munda kuburikidza nekushandiswa kwehuviri-mwenje yakasarudzika yekupfuura-gedhi tekinoroji. Muna 2023, timu kubva kuNational University of Defence Technology yakaronga kukurumidza PROOF maitiro, inonzi qPROOF, yekumisikidzwa kweakanyanya-wideband akasarudzika attosecond pulses.
Muna 2025, vaongorori kubva kuChinese Academy yeSainzi muShanghai vakagadzira tekinoroji yelaser synchronization yakavakirwa pane yakazvimiririra yakavakirwa nguva yekubatanidza sisitimu, ichigonesa yakakwirira-chaiyo nguva jitter kuyerwa uye chaiyo-nguva mhinduro yepicosecond lasers. Izvi hazvina kungodzora sisitimu nguva jitter mukati meatosecond renji asi zvakare yakasimbisa kuvimbika kweiyo laser system panguva yekushanda kwenguva refu. Iyo yakagadziridzwa yekuongorora uye yekudzora sisitimu inogona kuita chaiyo-nguva kururamisa kune nguva jitter. Mugore rimwe chetero, vaongorori vaishandisawo relativistic intensity spacetime vortices (STOV) lasers kugadzira ari ega attosecond gamma-ray pulses inotakura lateral orbital angular momentum.
Munda weattosecond lasers uri munguva yekukurumidza kusimudzira, inovhara akawanda maficha kubva pakutsvaga kwekutanga kuenda kukusimudzira kwekushandisa. Kuburikidza nekuedza kwezvikwata zvekutsvagisa zvesainzi, kuvakwa kwezvivakwa, kutsigirwa kwemitemo yenyika, uye kushandira pamwe nekutsinhana kwemumba neyekunze, dhizaini yeChina mumunda weatosecond lasers ichanakidzwa nebudiriro yakakura. Sezvo mamwe mayunivhesiti uye masangano ekutsvagisa ajoinha tsvagiridzo yeattosecond lasers, boka rematarenda ekutsvagisa kwesainzi ane maonero epasirese uye kugona kwehunyanzvi acharimwa, achisimudzira budiriro yakadzikama yeattosecond sainzi. National Attosecond hombe sainzi nzvimbo ichapawo inotungamira yekutsvagisa nharaunda yesainzi uye kuita mipiro yakakura mukufambisira mberi kwesainzi uye tekinoroji.
