Lub laser dawb yog ib hom laser qhov chaw uas tsim lub teeb hla tag nrho cov pom spectrum (los ntawm liab mus rau violet). Tsis zoo li ib txwm lasers, uas emit lub teeb ntawm ib lub wavelength, ib lub laser dawb siv cov tswv yim tshwj xeeb los tsim lub teeb uas zoo li lub teeb dawb. Lub laser dawb feem ntau hu ua "ze-dawb lub teeb" laser, raws li nws cov wavelength ntau npog tag nrho cov pom spectrum, thiab nws muaj peev xwm txawm muaj xws li ib feem ntawm lub ze-infrared thiab ultraviolet ntau yam.
Cov yam ntxwv tseem ceeb ntawm Dawb Laser:
Wide Spectral Output: Lub laser dawb tuaj yeem npog thaj tsam ntawm 400 nm (violet) txog 700 nm (liab), thiab qee zaum txawm tias dav dua, tsim lub teeb uas zoo ib yam li lub teeb dawb.
High Brightness: Dawb lasers muaj qhov ci ntsa iab heev. Piv nrog rau cov teeb pom kev zoo, lawv lub teeb tso zis ntau dua thiab muaj zog.
Tib lub teeb Source: Ib lub laser dawb yog ib qho laser, tsis zoo li kev sib txuas ntawm ntau qhov chaw teeb pom kev zoo tib yam, muab kev sib raug zoo thiab kev coj ua.
Txoj Cai Ua Haujlwm ntawm Dawb Laser:
Dawb lasers tuaj yeem tsim los ntawm ntau txoj hauv kev:
Dispersion-Based White Laser: Txoj kev no siv cov array ntawm lasers los tsim cov kab hluav taws xob sib txawv wavelengths. Cov kab teeb no tau muab tso ua ke siv cov khoom siv kho qhov muag tshwj xeeb (xws li cov fibers lossis cov khoom tawg) los tsim cov spectrum zoo li lub teeb dawb.
Fluorescent Conversion Dawb Laser: Txoj kev no siv xiav lossis violet lasers los ua kom muaj cov khoom siv fluorescent (xws li phosphor lossis fluorescent coatings). Cov ntaub ntawv no tawm lub teeb ntawm qhov sib txawv wavelengths, thiab thaum ua ke, lawv tsim lub teeb dawb. Ib qho piv txwv yog xiav laser zoo siab daj phosphors los tsim lub teeb dawb.
Fiber-Based Dawb Laser: Txoj kev no muaj fiber ntau doped nrog tshwj xeeb tsis tshua muaj-lub ntiaj teb cov ntsiab lus (xws li erbium, ytterbium, thiab lwm yam). Cov fiber ntau yog pumped nrog lub teeb los tsim broadband lub teeb, thiab los ntawm kev sib txuas cov khoom sib txawv ntawm laser, lub teeb dawb laser tso zis yog generated.
Daim ntawv thov ntawm Dawb Laser:
Zaub Technology: Cov lasers dawb tuaj yeem siv rau hauv cov khoom siv laser (xws li laser TVs thiab projectors). Lawv qhov dav xim gamut thiab siab brightness ua rau lawv lub teeb pom kev zoo nyob rau hauv cov khoom siv niaj hnub no.
Kev sib txuas lus kho qhov muag: Dawb lasers tuaj yeem siv rau hauv kev sib txuas lus kho qhov muag, tshwj xeeb tshaj yog nyob rau hauv kev sib txuas lus fiber ntau, qhov sib txawv wavelengths yog siv rau kev sib kis.
Kev Siv Tshuaj Kho Mob: Cov lasers dawb tuaj yeem siv rau hauv laser imaging thiab laser kho, muab siab dua precision thiab dav daim ntawv thov ntau yam.
Spectroscopy: Vim lawv qhov dav spectral tso zis, lasers dawb yog haum rau cov kev siv uas yuav tsum tau muaj ib tug dav spectrum, xws li spectral tsom xam thiab nrhiav tau cov khoom.
Teeb pom kev zoo: Vim lawv qhov ci ntsa iab thiab kev ua haujlwm siab, cov lasers dawb tau pib siv hauv kev lag luam teeb pom kev zoo, tshwj xeeb hauv cov khoom siv teeb pom kev zoo.
Kev Sib Tw thiab Kev Txhim Kho:
Thaum lub lasers dawb qhia tau hais tias muaj peev xwm zoo hauv ntau qhov chaw, thev naus laus zis ntsib ntau yam teeb meem:
Kev tsim khoom nyuaj: Kev tsim cov laser dawb nrog kev ua haujlwm siab kho qhov muag thiab cov khoom siv dav dav yuav tsum tau siv tshuab thiab khoom siv. Tseem muaj chaw rau kev txhim kho nyob rau hauv cov nqe lus ntawm efficiency thiab stability ntawm lub teeb qhov chaw.
Cov Nqi Them Nqi: Tam sim no, tus nqi ntawm cov lasers dawb yog qhov siab, tshwj xeeb tshaj yog rau cov fluorescent hloov dawb lasers, qhov twg cov nqi ntawm cov khoom siv fluorescent tuaj yeem kim heev.
Hauv cov ntsiab lus, cov lasers dawb yog cov thev naus laus zis zoo nrog kev siv dav hauv kev siv thev naus laus zis, kev sib txuas lus kho qhov muag, kev kho mob, thiab lwm yam. Txawm li cas los xij, cov teeb meem ntsig txog kev tsim khoom nyuaj thiab tus nqi yuav tsum tau daws rau lawv txoj kev siv dav.
