Muaj ntau txoj hauv kev rau kev faib cov laser, uas tuaj yeem muab faib ua cov khoom, roj, kua, semiconductor, dye thiaboptical fiber ntau.
(1) Solid State laser feem ntau me me thiab muaj zog, nrog lub zog hluav taws xob siab siab thiab dav siv ntau yam. Xws li: Nd: YAG laser. Nd (neodymium) yog ib pawg ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb, YAG sawv cev rau yttrium aluminium garnet, thiab cov qauv siv lead ua zoo ib yam li ruby. Tm: YAG, Ho: YAG, Ho: YAG, thiab lwm yam.
(2) Semiconductor lasers yog qhov me me, lub teeb hauv qhov hnyav, ntev hauv lub neej thiab yooj yim hauv cov qauv, uas yog tshwj xeeb tshaj yog siv rau hauv dav hlau, kev ua rog, tsheb thiab spaceships. Semiconductor laser tuaj yeem hloov lub wavelength ntawm laser los ntawm sab nraud hluav taws xob teb, magnetic teb, kub, siab thiab lwm yam, tuaj yeem hloov hluav taws xob ncaj qha rau hauv lub zog laser, yog li txoj kev loj hlob sai.
(3) Gas laser yog lub laser uas tso tawm tam sim no los ntawm Gas los tsim lub teeb coherent. Zoo monochromatic thiab coherence, laser wavelength tuaj yeem mus txog ntau txhiab hom, dav siv. Gas laser muaj cov qauv yooj yim, tus nqi qis thiab ua haujlwm yooj yim. Dav siv nyob rau hauv kev lag luam, kev ua liaj ua teb, tshuaj, precision ntsuas, holographic technology thiab lwm yam teb. Gas laser muaj hluav taws xob, thermal zog, tshuaj zog, lub teeb lub zog, nuclear zog thiab lwm yam excitation txoj kev.
(4) Dye lasers, uas cov kua Dye yog cov khoom ua haujlwm, tau tsim nyob rau xyoo 1966 thiab tau siv dav hauv ntau yam kev tshawb fawb tshawb fawb. Muaj txog 500 dyes uas tau pom los tsim cov lasers. Cov dyes tuaj yeem yaj hauv cawv, benzene, acetone, dej lossis lwm yam kev daws teeb meem. Lawv tuaj yeem muab tso rau hauv cov organic plastics hauv cov khoom siv, lossis sublimated rau hauv cov pa hauv daim ntawv gaseous. Yog li ntawd, dye laser kuj hu ua "kua laser". Cov yam ntxwv zoo tshaj plaws ntawm dye laser yog tias lub wavelength tsis tu ncua adjustable. Roj lasers muaj nyob rau hauv ntau yam kev siv, xws li spectroscopic, photochemical, kev kho mob, thiab kev ua liaj ua teb daim ntawv thov, uas tsis muaj nqi, high efficiency, thiab lub zog tso zis piv rau cov roj thiab cov khoom lub xeev lasers.
(5) Chemical lasers: Qee cov tshuaj tiv thaiv tsim kom muaj lub zog siab txaus kom tso tawm lub zog loj, uas tuaj yeem siv los tsim Laser txiav. Qhov no feem ntau yog siv riam phom. Hydrogen fluoride lasers, piv txwv li, tuaj yeem muab lub zog tso zis tas li hauv thaj tsam megawatt.
(6) Dawb electron laser xws li lasers yog tsim nyog tshaj li lwm hom rau tsim hluav taws xob hluav taws xob siab. Nws cov mechanism ua hauj lwm txawv. Nws tau txais kaum tawm lab tus volts high-zog kho electron beam los ntawm lub accelerator, thiab tsim lub zog theem ntawm lub zog sib txawv los ntawm lub sij hawm sib nqus teb, generating stimulated hluav taws xob.
(7) Excimer laser (qhov tseeb yog ib qho ntawm cov roj lasers) yog hom ultraviolet gaseous laser. Nws yog ib qho molecule tsim los ntawm kev sib xyaw ntawm cov roj inert thiab lwm cov roj (inert gas lossis halogen). Thaum lub laser yog launched rau hauv av, nws yog hu ua Excimer laser. Excimer laser yog ib lub zog qis laser uas tsis muaj thermal nyhuv. Nws yog ib tug pulse laser nrog muaj zog directivity, siab wavelength purity thiab loj tso zis zog. Lub zog photon wavelength ntau yog 157-353 nm, thiab lub sijhawm mem tes yog kaum ntawm nanoseconds. Feem ntau cov wavelengths yog 157 nm, 193 nm, 248 nm, 308 nm, thiab 351-353 nm.
(8) Fiber laser siv qhov nce nruab nrab (tsis tshua muaj lub ntiaj teb cov ntsiab lus) hauv Fiber los muab cov teeb liab optical amplification. Muaj ob homfiber ntaulaser: ib leeg-kawg twj tso kua mis thiab ob-kawg twj tso kua mis, tom kawg tuaj yeem ua tiav lub zog tso zis ntau dua. Lub coherent synthesis technology nyob rau hauv txoj kev loj hlob tuaj yeem txuas ntxiv lub zog tso zis.
(9) Hais txog kev txuas mus ntxiv, Nruam laser thiab Ultrashort Pulsed laser raug cais raws li hauv qab no: nanosecond (10e-6 SEC), picosecond (10e-9 SEC), femtosecond (10e-12 SEC ), thiab txawm attosecond (10e-15 SEC). Nruam laser, ntev mem tes laser thiab Ultrashort mem tes laser kuj ua rau lub hom phiaj nto, thiab cov thermal nyhuv txawv heev.
(10) Lwm hom laser muaj ntau, Raman laser Raman (laser), Hlau vapor laser (hlau vapor lasers), thiab hais txog. Yuav muaj ntau subdivisions rau ntau daim ntawv thov.
Raws li lub hauv paus ntawm Kev Lag Luam 4.0, laser yuav tseem ceeb dua.
