Fiber Coupled Diode Laser -pumped lasers yog qhov kev loj hlob sai thiab siv cov lasers tshiab hauv xyoo tsis ntev los no. Nws txoj kev loj hlob yog sib cais los ntawm kev txhim kho ntawm semiconductor lasers. Xyoo 1960 tawm thawj zaug ntawm thawj lub ruby lasers. Xyoo 1962 thawj qhov homogeneous hlaus gallium arsenide semiconductor lasers tawm los. Xyoo 1963, Newman thawj zaug tau thov siv cov semiconductor ua lub zog-xeev laser twj tso kua mis lub tswv yim. Nrog rau cov zis LD zog nce zuj zus, xyoo 1968 Ross thawj zaug paub txog kev siv GaAs Fiber Coupled Diode Laser nqus Nd: YAG laser. Thawj thawj zaug xyoo 1973, pulsed LD kawg xaus kev nrawm Nd: YAG lasers tau qhia thiab taw qhia qhov zoo ntawm qhov kawg ntawm kev nqus taub. Chesler thiab Singh muab cov qauv theoretical ntawm qhov kawg-pumped laser nyob rau ntau hom kev sib hloov thiab ib hom hloov chaw, thiab theoretical twj tso kua mis pib raws qhov kev xav ntawm cov twj tso kua mis tsis sib luag yog qhov ua tau zoo raws li cov kev sim sim. Xyoo 1976, Nd: YAG lasers nrog lub teeb pom kev zoo diodes tau nqus ntawm chav tsev qhov kub rau kev ua haujlwm tsis tu ncua. Txij li thaum xyoo 1980, semiconductor laser thiab nws cov haujlwm ntawm kev tshawb fawb tau ua rau muaj qhov kev sib tw loj, zoo heev txhawb cov khoom siv laser-thev naus laus zis, kev siv thev naus laus zis thiab daim ntawv thov, thiab ua rau muaj kev txhawb siab ntawm cov teeb meem ntawm lub xeev. Nrog rau cov tsos ntawm quantum zoo qauv thiab kev loj hlob ntawm kev siv lead ua kev loj hlob technology xws li hlau organic tshuaj vapor deposition (MOCVD) thiab molecular nqaj epitaxy (MBE), qhov pib ntawm LD tau pom tseeb txo, hloov dua siab tshiab txuag thiab tso zis hluav taws xob tau zoo dua tuaj. txhim kho, semiconductor laser array tso zis ntau zog ntawm 1W txog 2W. Ib tug tib LD nruam tso zis ntau zog ntawm 100mw rau 200mw.90 xyoo, lub Fiber Coupled Diode Laser ntau lawm technology thiab ntau lawm txheej txheem maj paub tab, lub neej, kev cia siab tau paub heev, uas DPL txoj kev loj hlob thiab daim ntawv thov tshiab kev kawm yog tshwj xeeb yog tseem ceeb. Xyoo 1992, Tebchaws Asmeskas Tshav Dav Hlau - Rivermore National Laboratory ua tiav kev tsim kho kilowatt-chav siab-lub zog hluav taws xob ntau lub diode-pumped lasers. Xyoo 1994, Asmeskas Lub Tsev Haujlwm Saib Xyuas Lub Zog tau tshaj tawm kev pom zoo" Kev Tshawb Fawb Kev Ruaj Ntseg Hauv Tebchaws GG; kev kawm. Xyoo 2001 Akiyama li al. Siv qhov peb-txoj kev ntawm sab-pumped Nd: YAG laser kom tau txais 5.4kW laser tso zis nrog kev siv hluav taws xob-hloov dua siab tshiab ntawm 22%. Xyoo 2002 Tebchaws Asmeskas lub tuam txhab TRW tau tsim kho 5.4kW tso zis Fiber Coupled Diode Laser nqus Nd: YAG laser. Nyob rau xyoo 2006 Tebchaws Asmeskas Nordisk tau ua tiav 19kW laser tsim tawm. Hauv cov ntsiab lus, DPL yog qhov feem ntau cov kev ua tau zoo thiab muaj kev pom zoo hauv cov khoom siv khov kho.
Raws li lub diode-pumped laser muaj qhov zoo ntawm lub zog loj, siab nqaj zoo cov zis, cov nyhuv ua haujlwm me, kev ua haujlwm siab thiab cov qauv me me, nws dhau los ua cov cuab yeej tseem ceeb ntawm cov ntaub ntawv siv thev naus laus zis. Nws cov ntawv thov siv dav, qhov dav yoj qhov ntau, qhov ceev ntawm kev txhim kho yog lwm hom lasers tsis tuaj yeem sib phim.
Tam sim no, daim teb ntawm diode-pumped solid-state lasers yog qhov dav heev, xws li tub rog, kev kho mob, kev lag luam thiab lwm cov teb.
Kev hloov pauv thiab nws cov txiaj ntsig lub zog raws li ultra-ceev high-power pulse qhov chaw, nrog kev rho tawm kho qhov muag, daim ntawv thov tom qab yog riam phom tiv thaiv cov cuab yeej, tuaj yeem tiv taus hluav taws xob cuam tshuam thiab txhim kho kev ntseeg tau; tib lub sij hawm, raws li ultra-ceev high-zog cov mem tes muaj peev xwm, cuam tshuam thiab kev sib cav, thiab cov khoom coj ua raug.
Pab pawg neeg tshawb fawb txawv teb chaws tau siv cov khoos phis tawm kho qhov muag kom tau txais cov xov tooj ntawm cov xov hluav taws xob tam sim no nyob rau saum npoo ntawm GaAs photoconductive hloov. Lub 1 cm qhov sib txawv hloov tau tshwm sim los ntawm lub teeb laser ntawm lub zog qib. Thaum qhov tsis ncaj ncees voltage yog 60 kV, tus nqi ntawm kA Qeb tam sim no.
Kev ua haujlwm ntawm qhov tsis ncaj ncees voltage yog qis dua qhov kev tshawb fawb txawv teb pawg 1 kev txiav txim siab ntawm lub zog loj, lub teeb tsa lub zog hluav taws xob qis dua qhov kev txiav txim txawv teb chaws 3 ntawm qhov loj, kev siv ntawm ib qho kev lag luam Fiber Coupled Diode Laser kom tau kA qhov siab ntawm lub siab tam sim no . Lub GaAs photoconductive hloov thiab nws cov teeb tsa lub zog nrog txhua yam khoom, me me, tus nqi pheej yig dua.
Works of innovation tsuas yog rau:
(1) GaAs Photoconductive Hloov rau Qhov Teeb Pom Ntawm Lub Teeb nrog Fiber Coupled Diode Laser, hloov cov tsoos hais ntawm lub zog loj-lub xeev laser. Koj tuaj yeem tau txais cov nqi qis, me-ntim high-power pulse qhov chaw.
(2) ntawm GaAs photoconductive hloov txhais cov qauv tsim, siab ua haujlwm siab, ua kom lub micro tsom mus rau qhov muag pom lub zog tsis muaj zog, lub sub-ohm load rau kA qhov loj ntawm lub zog tam sim no mem tes.
(3) siv tus qauv hluav taws xob hauv Circuit Court thiab lub tswv yim ntawm optical excitation charge sau los piav qhia txog hluav taws xob pulse waveform tsis tshwm sim vim raug xauv-vim muaj xwm txheej.
