Hauv cov thev naus laus zis laser niaj hnub no, cov diode pumping modules tau dhau los ua qhov chaw twj zoo tshaj plaws rau cov solid-state thiab fiber lasers vim lawv qhov ua haujlwm tau zoo, kev ntseeg siab, thiab kev tsim qauv me me. Txawm li cas los xij, ib qho ntawm cov yam tseem ceeb uas cuam tshuam rau lawv cov zis ua tau zoo thiab kev ruaj khov ntawm lub kaw lus yog qhov sib xws ntawm kev faib tawm hauv lub twj tso kua mis module.
1. Kev Sib Npaug ntawm Kev Faib Tawm ntawm Qhov Tau Txais yog dab tsi?
Hauv cov modules diode pumping, ntau lub laser diode bars tau teeb tsa ua ib qho array, thiab lawv lub teeb twj tso kua mis raug xa mus rau hauv qhov nruab nrab nce (xws li Yb-doped fiber lossis Nd: YAG crystal) los ntawm lub tshuab optical. Yog tias lub zog faib ntawm lub teeb twj tso kua mis tsis sib npaug, nws ua rau muaj qhov nce tsis sib xws hauv qhov nruab nrab, ua rau:
①Qhov tsis zoo ntawm lub teeb laser
②Txo qhov kev hloov pauv hluav taws xob tag nrho
③Kev ntxhov siab thermal ntau ntxiv thiab txo lub neej ntawm lub cev
④Muaj kev pheej hmoo ntau dua ntawm kev puas tsuaj rau qhov muag thaum lub sijhawm ua haujlwm
Yog li ntawd, kev ua tiav qhov sib npaug ntawm qhov chaw hauv kev faib lub teeb twj tso kua mis yog lub hom phiaj tseem ceeb hauv kev tsim thiab tsim cov twj tso kua mis.
2. Cov laj thawj feem ntau ntawm kev faib tawm tsis sib xws
①Kev hloov pauv hauv Chip Emission Power
Cov laser diode chips muaj qhov sib txawv ntawm lub zog. Yog tsis muaj kev cais lossis kev them nyiaj kom zoo, cov kev sib txawv no tuaj yeem ua rau lub zog twj tsis sib xws thoob plaws thaj chaw uas xav tau.
②Yuam Kev Hauv Collimation Thiab Focusing Systems
Qhov tsis sib haum lossis qhov tsis zoo ntawm cov khoom siv kho qhov muag (piv txwv li, FAC/SAC lenses, microlens arrays, fiber couplers) tuaj yeem ua rau qee qhov ntawm lub teeb tig ntawm lub hom phiaj xav tau, tsim cov hotspots lossis thaj chaw tuag.
③Cov teebmeem thermal gradient
Cov semiconductor lasers muaj kev rhiab heev rau qhov kub thiab txias. Kev tsim cov heatsink tsis zoo lossis kev txias tsis sib xws tuaj yeem ua rau muaj qhov sib txawv ntawm cov wavelength ntawm cov chips sib txawv, cuam tshuam rau kev sib txuas ua haujlwm zoo thiab kev sib xws ntawm cov zis.
④Tsim Cov Khoom Siv Fiber Tsis Txaus
Hauv cov qauv tsim tawm ntawm ntau lub fiber lossis cov qauv tsim tawm ntawm lub teeb, qhov kev teeb tsa tsis raug ntawm lub hauv paus kuj tseem tuaj yeem ua rau lub teeb pom kev tsis sib xws hauv qhov nruab nrab.
3. Cov txheej txheem los txhim kho qhov nce qib sib xws
①Kev cais cov nti thiab kev sib phim fais fab
Tshawb xyuas thiab muab cov chips laser diode ua pawg kom meej kom ntseeg tau tias muaj zog tso zis sib xws hauv txhua lub module, txo qhov kub hnyiab thiab qhov kub nce.
②Kev Tsim Kho Kom Zoo Dua
Siv cov optics uas tsis yog duab lossis cov lens homogenizing (piv txwv li, microlens arrays) los txhim kho qhov sib tshooj ntawm lub teeb thiab kev tsom mus rau qhov tseeb, yog li ua kom lub teeb pom kev zoo ntawm lub twj tso kua mis tiaj tus.
③Kev Tswj Xyuas Thermal Zoo Dua
Siv cov ntaub ntawv ua kom muaj cua sov siab (piv txwv li, CuW, CVD pob zeb diamond) thiab cov tswv yim tswj qhov kub thiab txias sib xws kom txo qhov hloov pauv ntawm qhov kub thiab txias ntawm cov chips thiab tswj cov zis ruaj khov.
④Kev Sib Koom Ua Ke ntawm Lub Teeb
Siv cov diffusers lossis cov khoom siv ua lub teeb raws txoj kev teeb pom kev zoo kom ua tiav qhov kev faib tawm ntawm lub teeb hauv qhov nruab nrab.
4. Tus Nqi Siv Tau Hauv Kev Siv Hauv Lub Ntiaj Teb Tiag
Hauv cov tshuab laser siab kawg—xws li kev ua haujlwm precision industrial, kev siv laser rau tub rog, kev kho mob, thiab kev tshawb fawb txog kev tshawb fawb—Qhov ruaj khov thiab qhov zoo ntawm lub teeb laser yog qhov tseem ceeb heev. Kev faib tawm tsis sib xws ntawm qhov nce siab ncaj qha cuam tshuam rau kev ntseeg tau thiab qhov tseeb ntawm lub kaw lus, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej hauv qab no:
①Cov lasers pulsed muaj zog heev: Tsis txhob muaj kev sib sau ua ke hauv zos lossis cov teebmeem tsis sib xws
②Cov tshuab hluav taws xob fiber laser: Tiv thaiv ASE (Amplified Spontaneous Emission) kev tsim khoom
③LIDAR thiab cov txheej txheem ntsuas qhov ntau thiab tsawg: Txhim kho qhov tseeb ntawm kev ntsuas thiab rov ua dua
④Cov laser kho mob: Xyuas kom meej tias lub zog tswj tau zoo thaum lub sijhawm kho mob
5. Xaus Lus
Qhov sib npaug ntawm kev faib tawm tej zaum yuav tsis yog qhov pom tseeb tshaj plaws ntawm lub twj tso kua mis, tab sis nws yog qhov tseem ceeb rau kev siv lub zog laser ua haujlwm siab. Raws li qhov xav tau ntawm qhov zoo thiab kev ruaj khov ntawm laser txuas ntxiv nce ntxiv, cov chaw tsim khoom ntawm lub twj tso kua mis yuav tsum kho"kev tswj hwm kev sib npaug"ua ib qho txheej txheem tseem ceeb—tsis tu ncua txhim kho kev xaiv cov chip, kev tsim qauv, thiab cov tswv yim thermal kom xa cov khoom siv laser txhim khu kev qha thiab sib xws rau cov ntawv thov downstream.
