Hauv kev siv laser hauv kev lag luam, lub diode pumping laser module ua haujlwm ua "lub hauv paus fais fab" ntawm lub laser system. Nws cov kev ua tau zoo cuam tshuam ncaj qha rau kev ua haujlwm zoo, lub neej ntev ntawm cov khoom siv, thiab qhov zoo ntawm cov khoom kawg. Txawm li cas los xij, nrog ntau yam diode pumping laser muaj nyob rau hauv kev ua lag luam (xws li hom kawg-pumped, sab-pumped, thiab fiber-coupled), ib tus neeg yuav ua li cas thiaj phim tau cov kev xav tau tshwj xeeb hauv kev lag luam? Tsab xov xwm no muab cov tswv yim xaiv raws li cov kev ntsuas kev siv tshuab thiab kev tshuaj xyuas raws li qhov xwm txheej.
1. Txhais cov Kev Xav Tau Tseem Ceeb ntawm Daim Ntawv Thov Kev Lag Luam
Ua ntej xaiv lub diode pumping laser module, nws yog ib qho tseem ceeb kom txhais cov ntsiab lus tseem ceeb ntawm daim ntawv thov scenario:
① Hom Ua Haujlwm
- Kev ua haujlwm tas mus li uas muaj zog heev (piv txwv li, txiav/vuam hlau tuab): Tso qhov tseem ceeb rau kev ruaj khov ntawm lub zog (>1kW) thiab lub peev xwm tso cua sov tawm.
- Kev siv tshuab micromachining kom raug (piv txwv li, kev khawb/etching cov khoom tawg yooj yim): Yuav tsum muaj qhov zoo ntawm lub teeb ci (M² < 10) thiab kev tswj lub zog ntawm lub zog (nanosecond level). - Kev ua haujlwm ceev ceev (piv txwv li, kev vuam roj teeb lithium): Yuav tsum muaj peev xwm teb sai (qhov rov ua dua hauv kHz ntau). ② Kev Hloov Kho Ib Puag Ncig - Ib puag ncig hnyav (piv txwv li, kub siab, plua plav, kev co xws li cov kab tsim khoom tsheb): Yuav tsum muaj qib kev tiv thaiv siab (IP65 lossis siab dua) thiab tsim qauv tiv taus kev poob siab. ③ Kev Xav Txog Tus Nqi Mus Ntev Cov khoom siv hauv kev lag luam feem ntau khiav 24/7, yog li nws tseem ceeb heev uas yuav tsum ntsuas qhov ua tau zoo ntawm electro-optical (> 30%), kev saib xyuas lub voj voog, thiab cov nqi khoom seem.
2. Cov Cim Qhia Txog Kev Ua Tau Zoo Tseem Ceeb Piav Qhia
① Lub zog tso zis thiab Beam zoo
- Lub Hwj Chim Ntau: Cov diode pumping laser modules qib kev lag luam feem ntau yog txij li 100W txog 10kW. Xaiv raws li cov khoom tuab (piv txwv li, txiav 20mm hlau xav tau ≥3kW).
- Qhov Zoo ntawm Beam (M² Factor):
- M² < 20: Haum rau kev ua cov khoom loj (piv txwv li, kev ntxuav qhov chaw).
- M² < 10: Haum rau kev vuam/txiav kom raug (piv txwv li, 0.1 hli stainless hlau). – Lus Cim: Lub zog siab dua feem ntau ua rau lub beam zoo tsis zoo; xav txog kev tsim cov twj tso kua mis sab lossis cov twj tso kua mis sib xyaw rau kev ua kom zoo dua. ② Electro-Optical Efficiency thiab Thermal Management – Electro-Optical Efficiency: Cuam tshuam ncaj qha rau cov nqi zog. Cov modules nrog >40% efficiency yog qhov nyiam dua (piv txwv li, diode pumping laser modules yog 2-3 npaug ntau dua li cov teeb-pumped ib txwm muaj).
- Tsim Kev Txias: Microchannel kua txias (kev ua haujlwm txias > 500W / cm²) yog qhov tsim nyog dua rau kev ua haujlwm ntev, kev thauj khoom siab dua li cua txias.
③ Kev Ntseeg Tau thiab Lub Neej Siv Tau Ntev
- MTBF (Lub Sijhawm Nruab Nrab Ntawm Kev Ua Tsis Tau Zoo): Cov chaw ua haujlwm hauv kev lag luam xav tau ≥50,000 teev.
- Kev Tiv Thaiv Kev Kis Kab Mob: Lub qhov muag kaw kaw tiv thaiv cov hlau txaws thiab cov hmoov av nkag (IP67 qib zoo dua).
④ Kev Sib Haum Xeeb thiab Kev Loj Hlob
- Kev Sib Txuas Lus Tswj: Kev txhawb nqa rau cov txheej txheem kev lag luam xws li EtherCAT thiab RS485 pab txhawb kev koom ua ke rau hauv cov kab ntau lawm tsis siv neeg.
- Kev Nthuav Dav Modular: Kev txhawb nqa rau ntau lub module sib luag (piv txwv li, 6-hauv-1 stacking) tso cai rau kev hloov kho hluav taws xob tsis muaj teeb meem.
⑤ Cov yam ntxwv ntawm qhov ntev ntawm lub zog thiab lub zog ntawm lub plawv dhia
- Kev Sib Tw Ntev Ntev:
- 1064nm: Feem ntau siv rau kev ua hlau.
- 532nm/355nm: Haum rau kev ua cov khoom siv tsis yog hlau xws li iav thiab ceramics.
- Kev Tswj Lub Plawv:
- QCW (Quasi-Continuous Wave) hom yog qhov zoo tagnrho rau kev siv zog siab, qis zaus (piv txwv li, kev kos duab tob).
- Qhov zaus rov ua dua siab (MHz theem) yog qhov tsim nyog rau kev cim ceev ceev.
3. Tsis txhob ua tej yam tsis zoo uas yuav tshwm sim los ntawm kev xaiv tsa
- Qhov Teeb Meem 1: "Lub zog siab dua, qhov zoo dua" - Lub zog ntau dhau yuav ua rau cov khoom kub hnyiab. Kev sib npaug ntawm lub zog thiab qhov zoo ntawm lub teeb.
- Qhov Teeb Meem 2: "Tsis quav ntsej txog cov nqi kho mus sij hawm ntev" - Cov modules uas tsis ua haujlwm zoo tuaj yeem raug nqi hluav taws xob thiab kev kho ntau dua, ntau dua li cov nyiaj txuag thaum pib.
- Qhov Teeb Meem 3: "Ib qho module loj-haum-txhua tus rau txhua qhov xwm txheej" - Kev ua tiav thiab kev ua tiav tsis zoo yuav tsum muaj kev tsim qauv sib txawv (piv txwv li, kev sib xyaw ua ke ntawm cov tshuaj doping, cov qauv twj tso kua mis).
