Nyob rau hauv kev lag luam laser daim ntaub ntawv, lub diode pumping laser module ua hauj lwm raws li lub "power core" ntawm lub laser system. Nws qhov kev ua tau zoo cuam tshuam ncaj qha rau kev ua haujlwm, cov khoom siv lub neej ntev, thiab cov khoom zoo kawg nkaus. Txawm li cas los xij, nrog ntau yam diode siv laser muaj nyob rau hauv kev ua lag luam (xws li qhov kawg-pum, sab-pumped, thiab fiber ntau-coupled hom), yuav ua li cas kom tau raws li cov kev cai tshwj xeeb? Kab lus no muab cov tswv yim xaiv cov txheej txheem raws li cov txheej txheem kev ua haujlwm thiab kev txheeb xyuas qhov xwm txheej.
1. Txhais cov ntsiab lus tseem ceeb ntawm Daim Ntawv Thov Kev Lag Luam
Ua ntej xaiv lub diode pumping laser module, nws yog ib qho tseem ceeb uas yuav tau txheeb xyuas qhov tseem ceeb ntawm daim ntawv thov scenario:
① Hom kev ua haujlwm
- Kev ua haujlwm siab ua haujlwm tsis tu ncua (piv txwv li, tuab hlau txiav / vuam): Ua ntej lub zog ruaj khov (> 1kW) thiab muaj peev xwm ua kom sov.
- Precision micromachining (piv txwv li, nkig khoom drilling / etching): Yuav tsum tau siab beam zoo (M² <10) thiab meej mem tes tswj (nanosecond theem). - Dynamic high-speed processing (piv txwv li, lithium roj teeb tab welding): Yuav tsum muaj peev xwm teb tau sai (repetition rate in the kHz range). ② Environmental Adaptability - Ib puag ncig hnyav (xws li, kub siab, plua plav, kev co xws li tsheb tsim cov kab): Yuav tsum muaj kev tiv thaiv siab (IP65 lossis siab dua) thiab tsim kev poob siab. ③ Kev txiav txim siab txog tus nqi mus sij hawm ntev Cov cuab yeej siv feem ntau ua haujlwm 24/7, yog li nws yog ib qho tseem ceeb rau kev ntsuam xyuas electro-optical efficiency (> 30%), kev tu lub voj voog, thiab cov nqi seem.
2. Piav qhia txog kev ua tau zoo
① Tso zis fais fab thiab nqaj zoo
- Lub Hwj Chim Loj: Muaj qib diode siv laser modules feem ntau ntawm 100W txog 10kW. Xaiv raws li cov khoom thickness (xws li, txiav 20mm steel yuav tsum ≥3kW).
- Beam Quality (M² Factor):
- M² < 20: Tsim nyog rau kev ua haujlwm ntxhib (xws li, ntxuav qhov chaw).
- M² <10: Haum rau precision vuam / txiav (xws li, 0.1mm stainless hlau). - Ceeb toom: Lub zog siab dua feem ntau cuam tshuam cov kab teeb pom kev zoo; xav txog sab-pumped lossis hybrid-pumping designs rau optimization. ② Electro-Optical Efficiency thiab Thermal Management - Electro-Optical Efficiency: Ncaj qha cuam tshuam rau cov nqi hluav taws xob. Modules nrog> 40% efficiency yog nyiam (xws li, diode siv laser modules yog 2-3 npaug ntau npaum li cov tsoos teeb-tswj sawv daws yuav).
- Txias Tsim: Microchannel kua txias (kev ua kom txias> 500W / cm²) yog qhov tsim nyog rau lub sijhawm ntev, kev ua haujlwm siab tshaj li cua txias.
③ Kev ntseeg tau thiab lub neej ntev
- MTBF (Lub Sijhawm Nruab Nrab Nruab Nrab Tsis Ua Haujlwm): Kev lag luam ib puag ncig xav tau ≥50,000 teev.
- Kev Tiv Thaiv Kev Tiv Thaiv: Lub kaw lus kho qhov muag tiv thaiv cov hlau txaws thiab plua plav nkag (IP67 qhov ntsuas zoo dua).
④ Compatibility thiab Scalability
- Tswj Interface: Kev them nyiaj yug rau cov txheej txheem kev lag luam xws li EtherCAT thiab RS485 txhawb kev koom ua ke rau hauv cov kab ntau lawm.
- Modular Expansion: Kev them nyiaj yug rau ntau qhov kev sib txuas ua ke (piv txwv li, 6-hauv-1 stacking) tso cai rau kev hloov kho lub zog seamless.
⑤ Cov yam ntxwv wavelength thiab mem tes
- Kev sib tw wavelength:
- 1064nm: Feem ntau rau kev ua hlau.
- 532nm / 355nm: Haum rau kev ua tiav ntawm cov khoom tsis yog xim hlau xws li iav thiab ceramics.
- Pulse Control:
- QCW (Quasi-Nruam Wave) hom yog qhov zoo tagnrho rau kev siv lub zog siab, qis zaus (xws li, sib sib zog nqus engraving).
- High repetition zaus (MHz theem) yog haum rau high-speed marking.
3. Zam kev xaiv pitfalls
- Pitfall 1: "Lub zog siab dua, qhov zoo dua" - Lub zog ntau dhau tuaj yeem ua rau cov khoom hlawv. Sib npaug zog thiab beam zoo.
- Pitfall 2: "Tsis quav ntsej cov nqi tu mus sij hawm ntev" - Cov khoom siv hluav taws xob tsawg tuaj yeem ua rau muaj hluav taws xob ntau dua thiab cov nqi kho mob thaum lub sij hawm, tshaj qhov nyiaj tau los pib.
- Pitfall 3: "Ib-loj-fits-tag nrho module rau txhua qhov xwm txheej" - Precision thiab coarse processing yuav tsum tau sib txawv designs (xws li, doping concentration, twj tso kua mis qauv).
