1.disc laser
Lub tswv yim ntawm Disk Laser tsim lub tswv yim zoo daws qhov teeb meem thermal effect ntawm solid-state lasers thiab ua tiav kev sib xyaw ua ke zoo tshaj plaws ntawm lub zog nruab nrab, siab ncov lub zog, kev ua haujlwm siab, thiab cov kab hluav taws xob siab zoo ntawm cov khoom hauv lub xeev lasers.Disk lasers tau dhau los ua qhov hloov tsis tau tshiab laser lub teeb rau kev ua haujlwm hauv tsheb, nkoj, tsheb ciav hlau, aviation, lub zog thiab lwm yam haujlwm.Tam sim no high-power disc laser tshuab muaj lub zog siab tshaj plaws ntawm 16 kilowatts thiab beam zoo ntawm 8 hli milliradians, uas enables neeg hlau laser tej thaj chaw deb welding thiab loj-hom laser high-ceev txiav, qhib dav prospects rau solid-state lasers nyob rau hauv thaj teb ntawmhigh-power laser ua.Kev ua lag luam.
Qhov zoo ntawm disc lasers:
1. Modular qauv
Lub disc laser txais cov qauv qauv, thiab txhua qhov module tuaj yeem hloov tau sai ntawm qhov chaw.Lub tshuab cua txias thiab lub teeb qhia kev sib xyaw ua ke nrog lub laser qhov chaw, nrog cov qauv compact, me me hneev taw thiab ceev installation thiab debugging.
2. Zoo beam zoo thiab standardized
Txhua TRUMPF disc lasers tshaj 2kW muaj cov khoom lag luam kab teeb (BPP) tus qauv ntawm 8mm / mrad.Lub laser yog invariant rau kev hloov hauv kev khiav hauj lwm hom thiab yog sib xws nrog tag nrho cov TRUMPF optics.
3. Txij li thaum qhov chaw loj nyob rau hauv lub disc laser yog loj, lub optical hwj chim ceev endured los ntawm txhua qhov chaw kho qhov muag yog me me.
Qhov kev puas tsuaj ntawm cov khoom siv kho qhov muag txheej feem ntau yog li 500MW / cm2, thiab qhov kev puas tsuaj ntawm quartz yog 2-3GW / cm2.Lub zog ceev hauv TRUMPF disk laser resonant kab noj hniav feem ntau yog tsawg dua 0.5MW / cm2, thiab lub zog ceev ntawm cov coupling fiber yog tsawg dua 30MW / cm2.Xws li lub zog qis qis yuav tsis ua rau muaj kev puas tsuaj rau cov khoom siv kho qhov muag thiab yuav tsis tsim cov teebmeem nonlinear, yog li ua kom muaj kev ntseeg siab ua haujlwm.
4. Txais laser zog real-time tawm tswv yim tswj qhov system.
Lub sij hawm tawm tswv yim tswj qhov system tuaj yeem ua kom lub zog ncav cuag T-thooj ruaj khov, thiab cov txiaj ntsig tau ua tau zoo dua qub.Lub sij hawm preheating ntawm lub disc laser yog yuav luag xoom, thiab adjustable hwj chim ntau yog 1% -100%.Txij li thaum lub disc laser tiav daws qhov teeb meem ntawm thermal lens nyhuv, lub laser lub zog, qhov loj me, thiab beam divergence lub kaum sab xis yog ruaj khov nyob rau hauv tag nrho cov hwj huam ntau, thiab lub wavefront ntawm lub beam tsis mus distortion.
5. Cov fiber ntau optical tuaj yeem ntsaws-thiab-ua si thaum lub laser tseem khiav.
Thaum qee qhov kho qhov muag tsis ua haujlwm, thaum hloov kho qhov muag fiber ntau, koj tsuas yog yuav tsum kaw txoj kev kho qhov muag ntawm qhov kho qhov muag tsis tau kaw, thiab lwm cov fibers kho qhov muag tuaj yeem txuas ntxiv tso tawm lub teeb laser.Kev hloov kho qhov muag fiber ntau yog ib qho yooj yim rau kev khiav lag luam, ntsaws thiab ua si, tsis muaj cov cuab yeej lossis kev hloov kho kom haum.Muaj cov khoom pov thawj plua plav ntawm txoj kev nkag mus kom nruj kom tsis txhob muaj plua plav nkag mus rau thaj chaw kho qhov muag.
6. Muaj kev nyab xeeb thiab txhim khu kev qha
Thaum lub sijhawm ua haujlwm, txawm tias qhov emissivity ntawm cov khoom ua tiav yog siab heev uas lub teeb laser tau rov qab los rau hauv lub laser, nws yuav tsis muaj kev cuam tshuam rau lub laser nws tus kheej lossis cov nyhuv ua, thiab yuav tsis muaj kev txwv rau cov khoom siv lossis fiber ntev.Kev nyab xeeb ntawm kev ua haujlwm laser tau txais daim ntawv pov thawj kev nyab xeeb German.
7. Lub twj tso kua mis diode module yog yooj yim dua thiab sai dua
Lub diode array mounted ntawm lub twj tso kua mis module kuj yog kev tsim kho modular.Diode array modules muaj lub neej ua haujlwm ntev thiab tau lav rau 3 xyoos lossis 20,000 teev.Tsis tas yuav muaj lub sijhawm poob qis txawm tias nws yog qhov kev npaj hloov pauv lossis hloov tam sim vim qhov tsis ua tiav tam sim ntawd.Thaum lub module tsis ua hauj lwm, lub kaw lus tswj yuav ceeb toom thiab cia li nce tam sim no ntawm lwm cov modules tsim nyog kom lub laser tso zis hwj chim tas li.Tus neeg siv tuaj yeem ua haujlwm txuas ntxiv rau kaum lossis txawm kaum ob teev.Hloov cov twj tso kua mis diode ntawm qhov chaw tsim khoom yog qhov yooj yim heev thiab yuav tsum tsis muaj kev cob qhia tus neeg siv khoom.
Fiber lasers, zoo li lwm yam lasers, yog tsim los ntawm peb qhov chaw: ib tug nce nruab nrab (doped fiber) uas muaj peev xwm tsim photons, ib tug optical resonant kab noj hniav uas tso cai rau photons rov qab thiab resonantly amplified nyob rau hauv nruab nrab nce, thiab ib tug twj tso kua mis qhov chaw uas excites. photon kev hloov pauv.
Nta: 1. Optical fiber ntau muaj qhov "surface area/volume" ratio, zoo thermal dissipation effect, thiab tuaj yeem ua haujlwm tsis tu ncua yam tsis tau yuam kom txias.2. Raws li ib tug waveguide nruab nrab, optical fiber muaj ib tug me me txoj kab uas hla thiab yog nquag muaj zog ceev ceev nyob rau hauv lub fiber.Yog li ntawd, fiber ntau lasers muaj kev hloov dua siab tshiab dua, qis dua, nce siab dua, thiab cov kab dav dav dua, thiab sib txawv ntawm fiber ntau optical.Coupling poob yog me me.3. Vim tias cov fibers kho qhov muag muaj qhov ua tau zoo, fiber ntau lasers me me thiab hloov tau yooj yim, compact hauv cov qauv, tus nqi tsim nyog, thiab yooj yim rau kev sib koom ua ke.4. Kev kho qhov muag fiber ntau kuj muaj ntau yam tsis tunable thiab xaiv, thiab tuaj yeem tau txais ntau qhov sib txawv, zoo dispersion thiab stability.
Fiber ntau laser classification:
1. Tsis tshua muaj ntiaj teb doped fiber ntau laser
2. Tsis tshua muaj ntiaj teb cov ntsiab lus doped nyob rau hauv tam sim no kuj paub tab active optical fibers: erbium, neodymium, praseodymium, thulium, thiab ytterbium.
3. Cov ntsiab lus ntawm fiber ntau stimulated Raman scattering laser: Fiber laser yog qhov tseem ceeb ntawm lub wavelength converter, uas tuaj yeem hloov lub twj tso kua mis wavelength mus rau lub teeb ntawm ib lub wavelength tshwj xeeb thiab tso tawm rau hauv daim ntawv ntawm laser.Los ntawm kev pom lub cev, lub hauv paus ntsiab lus ntawm kev tsim lub teeb amplification yog muab cov khoom siv ua haujlwm nrog lub teeb ntawm lub wavelength uas nws tuaj yeem nqus tau, kom cov khoom siv ua haujlwm tuaj yeem nqus tau lub zog thiab ua haujlwm.Yog li ntawd, nyob ntawm cov khoom siv doping, qhov sib nqus nqus wavelength kuj txawv, thiab lub twj tso kua mis Cov kev xav tau ntawm lub teeb lub teeb kuj txawv.
2.3 Semiconductor Laser
