Iindlela zokuhlaziya ukukhanya zibalulekile kuluntu lwanamhlanje kuba zivumela ukuchongwa ngokukhawuleza nangokukhuselekileyo kwezinto ezikwizinto eziqinileyo, ulwelo okanye iigesi. Ezi ndlela zixhomekeke ekukhanyeni okunxibelelana ngokwahlukileyo nezi zinto kwiindawo ezahlukeneyo ze-spectrum. Umzekelo, i-ultraviolet spectrum inokufikelela ngqo kwiinguqu ze-elektroniki ngaphakathi kwento, ngelixa i-terahertz inovelwano kakhulu kwiintshukumo zeemolekyuli.
Umfanekiso wobugcisa we-mid-infrared pulse spectrum ngasemva kwentsimi yombane evelisa i-pulse
Iiteknoloji ezininzi eziphuhliswe kule minyaka idlulileyo ziye zavumela i-hyperspectroscopy kunye nemifanekiso, nto leyo evumela izazinzulu ukuba zibone izinto ezifana nokuziphatha kwee-molecules njengoko zigoba, zijikeleza okanye zingcangcazela ukuze ziqonde iimpawu zomhlaza, iigesi ezigcina ubushushu, ukungcola, kwanezinto ezinobungozi. Ezi teknoloji zinobukrelekrele kakhulu ziye zabonakala ziluncedo kwiindawo ezifana nokufumanisa ukutya, ukuqonda iikhemikhali, kwanelifa lenkcubeko, kwaye zinokusetyenziselwa ukufunda ulwakhiwo lwezinto zakudala, imizobo, okanye izinto eziqingqiweyo.
Umceli mngeni osele ukho ixesha elide kukungabikho kwemithombo yokukhanya emincinci ekwaziyo ukugubungela uluhlu olukhulu kangaka lwe-spectral kunye nokukhanya okwaneleyo. Ii-Synchrotrons zinokubonelela nge-spectral coverage, kodwa azinawo ukuhambelana kwexesha kwee-laser, kwaye loo mithombo yokukhanya ingasetyenziswa kuphela kwiindawo ezinkulu zabasebenzisi.
Kwisifundo sakutshanje esipapashwe kwiNature Photonics, iqela labaphandi bamazwe ngamazwe abavela kwiSpanish Institute of Photonic Sciences, iMax Planck Institute for Optical Sciences, iKuban State University, kunye neMax Born Institute for Nonlinear Optics kunye neUltrafast Spectroscopy, phakathi kwezinye, baxela umthombo oqinileyo nokhanyayo we-mid-infrared driver. Idibanisa i-inflatable anti-resonant ring photonic crystal fiber kunye ne-nonlinear crystal entsha. Esi sixhobo sinika i-spectrum edibeneyo ukusuka kwi-340 nm ukuya kwi-40,000 nm kunye nokukhanya kwe-spectral okuphindwe kabini ukuya kwesihlanu okuphezulu kunesinye sezixhobo ezikhanyayo ze-synchrotron.
Izifundo zexesha elizayo ziza kusebenzisa ixesha eliphantsi lokukhanya komthombo wokukhanya ukwenza uhlalutyo lwexesha lezinto kunye nezinto, zivula iindlela ezintsha zokulinganisa izinto ezininzi kwiindawo ezifana ne-molecular spectroscopy, i-physical chemistry okanye i-solid state physics, batsho abaphandi.
