Cov khoom lag luam txiav-ntev feem ntau pib hauv kev tshawb fawb kev kawm. Hauv ntau qhov xwm txheej, cov kws tshaj lij pib cov tuam txhab lawv tus kheej lossis nyiam cov tub ua lag luam rau daim ntawv tso cai thev naus laus zis tau yug los hauv chav kuaj kev kawm, yog li hloov lawv mus rau hauv cov khoom lag luam.
Thaum cov kws tshawb fawb kev kawm tsim cov khoom tshiab, lawv feem ntau tsim thiab tsim lawv siv ntau yam sib txawv. Thaum tej yam kev mob tso cai, lawv integrate off-the-shelf Cheebtsam rau hauv cov khoom kawg. Raws li daim ntawv thov kev thov nce zuj zus, cov khoom siv ntawm cov khoom no tau nce zuj zus thiab tshwj xeeb.
Pulse-based tunable lasers, piv txwv li, yuav tsum tau hloov pauv tau yooj yim, muaj peev xwm tsim tau ntau yam ntawm wavelengths los ntawm pom mus rau ultraviolet sib sib zog nqus, thiab outputting high-siv pulses nyob rau hauv nanosecond increments. Lawv muaj ntau yam kev siv xws li, tab sis tsis txwv rau, fiber optic cov ntaub ntawv kis tau tus mob, ion desorption, tshav kub tiam, ultrasonic tiam, hluav taws xob excitation, thiab lwm yam. Nws yog los ntawm kev tsim txiaj ntawm lawv qhov kev hloov pauv tau zoo uas cov lasers ua lub luag haujlwm tseem ceeb hauv thaj chaw ntawm lub sijhawm daws teeb meem lub cev chemistry, huab hwm coj spectrometry, photoacoustic imaging, spectroscopy, spectrophotometric, diagnostics, thiab hyperspectral imaging.
Ntawm cov lasers pulsed no, Optical Parametric Oscillator (OPO) lasers sawv tawm rau lawv qhov yooj yim thiab kev lag luam, raws li lawv tuaj yeem "tuned" rau ntau qhov dav ntawm cov wavelengths tshwj xeeb.
Tom qab ntau tshaj 35 xyoo ntawm kev hloov kho thev naus laus zis, OPO lasers tau ua lag luam. Thaum Ntxov OPO tshuab tau loj heev thiab ua yuam kev uas lawv tau tsim thiab muag hauv chaw nres tsheb. Niaj hnub no OPOs tau hloov pauv mus rau hauv kev sib xyaw ua ke, ntsaws-thiab-ua si uas tsis tas yuav teeb tsa thiab calibration los ntawm cov kws tshaj lij laser tshwj xeeb. Niaj hnub nimno OPOs tuaj yeem yooj yim ua ke rau hauv OEM systems nrog kev tswj xyuas zoo.
Qhov kev nce qib no yog qhov ua tau zoo rau biologists, chemists, physicists, kws tshawb fawb thiab lwm cov kws tshawb fawb kev kawm. Thaum lawv tau ua tiav zoo hauv lawv cov haujlwm, lawv yuav tsis muaj kev paub tshwj xeeb ntawm kev tsim laser lossis tuning.
"Op-the-shelf OPOs yog tsim los rau cov neeg uas tsis paub ntau txog optics lossis yuav ua li cas kho lasers," said Dr. Mark Little. Nws yog tus kws tshaj lij kev lag luam thiab kev tshawb fawb txog kev lag luam rau OPOTEK, LLC hauv Carlsbad, California, lub ntiaj teb cov chaw tsim khoom ntawm tunable lasers. "Qhov tseeb, nws yog 'lub thawv dub' uas tuaj yeem yooj yim ua ke rau hauv lwm qhov kev tsim kho."
