Inqubekelaphambili enkulu, ososayensi bathuthukisa umthombo wokukhanya ohambisanayo wokukhanya okuphezulu!

Izindlela zokubona ezihlaziyayo zibalulekile emphakathini wanamuhla ngoba zivumela ukuhlonzwa okusheshayo nokuphephile kwezinto ezikuqinile, uketshezi noma amagesi. Lezi zindlela zincike ekukhanyeni okusebenzisana ngokuhlukile nalezi zinto ezingxenyeni ezihlukene ze-spectrum. Isibonelo, i-spectrum ye-ultraviolet inokufinyelela okuqondile ekushintsheni kwe-electronic ngaphakathi kwento, kuyilapho i-terahertz izwela kakhulu ekudlidlizeni kwamangqamuzana.

Isithombe sobuciko se-mid-infrared pulse spectrum ngemuva kwenkundla kagesi ekhiqiza i-pulse

Ubuchwepheshe obuningi obuthuthukisiwe phakathi neminyaka buye benza i-hyperspectroscopy ne-imaging, okuvumela ososayensi ukuthi babone izinto ezinjengokuziphatha kwama-molecule njengoba egoqa, ephenduka noma edlidliza ukuze aqonde izimpawu zomdlavuza, amagesi abamba ukushisa, izinto ezingcolisayo, ngisho nezinto eziyingozi. Lobu buchwepheshe obuzwela kakhulu bubonakale buwusizo ezindaweni ezifana nokutholwa kokudla, inzwa ye-biochemical, ngisho namagugu amasiko, futhi bungasetshenziswa ukutadisha ukwakheka kwezinto zakudala, imidwebo, noma izinto ezibaziwe.

Inselele yesikhathi eside kube ukuntuleka kwemithombo yokukhanya ehlangene ekwazi ukumboza ububanzi obunjalo bokubukeka nokukhanya okwanele. Ama-synchrrons anganikeza ukumbozwa kwe-spectral, kodwa awanakho ukuhambisana kwesikhashana kwama-lasers, futhi imithombo enjalo yokukhanya ingasetshenziswa kuphela ezindaweni zabasebenzisi abakhulu.

Ocwaningweni lwakamuva olushicilelwe ku-Nature Photonics, ithimba lamazwe ngamazwe labacwaningi abavela e-Spanish Institute of Photonic Sciences, i-Max Planck Institute for Optical Sciences, i-Kuban State University, kanye ne-Max Born Institute for Nonlinear Optics and Ultrafast Spectroscopy, phakathi kwabanye, kubika. umthombo womshayeli ohlangene, okhanya kakhulu omaphakathi ne-infrared. Ihlanganisa indandatho ye-anti-resonant photonic crystal fiber ene-novel nonlinear crystal. Idivayisi iletha i-spectrum ehambisanayo ukusuka ku-340 nm kuya ku-40,000 nm enokukhanya kwe-spectral okulandelanayo okuphindwe kabili kuya kwamahlanu kobukhulu kunomunye wedivayisi egqama kakhulu ye-synchrotron.

Ucwaningo lwesikhathi esizayo luzosebenzisa isikhathi esiphansi somthombo wokukhanya we-pulse ubude ukwenza ukuhlaziya kwesizinda sesikhathi sezinto nezinto zokwakha, kuvule izindlela ezintsha zezindlela zokulinganisa i-multimodal ezindaweni ezifana ne-molecular spectroscopy, i-physical chemistry noma i-solid state physics, abacwaningi bathi.
