Tsis ntev los no, pab neeg tshawb fawb los ntawm Harvard University University thiab tshaj tawm tias lawv tau ua tiav cov lus qhia txog kev sib tw ua laser. Cov cuab yeej tshiab laser tuaj yeem ua rau muaj cov khoom siv optical, ua tiav cov khoom siv tsis sib haum xeeb thiab theem kev hloov pauv ntawm lub tshuab hluav taws xob, ntawm cov laser tshuab, thiab kev ntsuas zoo nkauj.
Cov pab pawg neeg tshawb fawb tau hais tias cov mem tes no mem tes no tuaj yeem muab rho tawm thiab nthuav dav rau ntau qhov kev sim kho kho tshiab. Ib qho ntxiv, lub laser system kuj muab cov peev txheej tshiab rau daim ntawv thov ntawm dual-zuag spectroscopy.
Dual-zuag spectroscopy yog qhov kev daws teeb meem siab, ceev spectral kev tshawb xyuas cov qauv uas siv tau rau hauv kev nqus roj av thiab lwm thaj teb. Tus txheej txheem ntawm cov thev naus laus zis no yog siv ob zaus sib txawv ntawm cov qauv ntsuas kom tau txais cov ntaub ntawv kho qhov muag tau hloov kho kom tau hloov kho qhov ntsuas hluav taws xob. Cov qauv no tau txhim kho qhov nrawm thiab qhov tseeb ntawm kev txheeb xyuas qhov tseeb, thiab cov khoom lag luam laser ua kom muaj peev xwm ua tau ob qho tib si tshwj xeeb ua rau muaj kev sib tw thev naus laus zis.
