Cov kws tshawb nrhiav ntawm Massachusetts Lub Tsev Kawm Ntawv Txuj Ci (MIT) thiab University of Waterloo tau tsim lub zog loj, lub luag haujlwm ntawm lub zog me me ntawm lub teeb laser uas tuaj yeem tsim terahertz hluav taws xob sab nraud qhov chaw kuaj. Qhov laser no tuaj yeem siv rau hauv thaj chaw xws li thaj chaw muaj tseeb ntawm kev mob qog nqaij daim tawv thiab kuaj cov khoom tawg.
Cov lasers no tsuas yog ob peb millimeters ntev thiab yog quantum zoo qauv nrog ua tib zoo tsim lub qhov dej thiab kev txwv. Hauv cov qauv no, xaim hluav taws xob" cascade" nqes ib hom ntaiv, txhua kauj ruam uas tso tawm qhov hluav taws xob me me, uas yog, photon. Lub tswv yim tshiab hauv kev tshawb nrhiav yog qhov siab ob npaug ntawm qhov thaiv txoj hauv sab hauv lub laser kom tiv thaiv xau hluav taws xob ntawm cov hluav taws xob, uas zoo li nce ntawm siab kub.
Hauv thaj chaw kho mob, lub tshuab tshiab no suav nrog lub koob yees duab ua kom pom me me thiab kuaj xyuas, uas tuaj yeem ua haujlwm hauv txhua qhov chaw nrog lub qhov hluav taws xob, thiab tuaj yeem muab cov duab pom tseeb rau lub sijhawm kuaj mob tawv nqaij thiab txawm tias thaum phais mob kom tshem tawm cov nqaij hlav tawv nqaij. Professor Hu hais tias cov kab mob cancer "ua kom meej meej hauv terahertz" vim tias lawv cov dej thiab ntshav ntau yog siab tshaj cov hlwb ib txwm. Lub tshuab thev naus laus zis tseem tuaj yeem siv rau ntau qhov kev lag luam uas xav tau kuaj cov khoom txawv teb sab hauv cov khoom kom ntseeg tau cov khoom nyab xeeb thiab zoo.
