Nyob rau hauv niaj hnub laser tshuab, diode twj tso kua mis modules tau dhau los ua qhov zoo tshaj plaws twj tso kua mis qhov chaw rau solid-state thiab fiber lasers vim lawv high efficiency, kev cia siab, thiab compact tsim. Txawm li cas los xij, ib qho tseem ceeb cuam tshuam rau lawv cov txiaj ntsig kev ua tau zoo thiab kev ruaj ntseg system yog qhov sib xws ntawm kev faib khoom hauv lub twj tso kua mis module.
1. Gain Distribution Uniformity yog dab tsi?
Nyob rau hauv diode twj tso kua mis modules, ntau laser diode tuav yog teem nyob rau hauv ib tug array, thiab lawv lub teeb lub twj tso kua mis yog xa mus rau hauv lub nce nruab nrab (xws li Yb-doped fiber los yog Nd: YAG siv lead ua) los ntawm ib tug optical system. Yog hais tias lub zog faib ntawm lub twj tso kua mis lub teeb tsis sib npaug, nws ua rau asymmetric nce hauv nruab nrab, ua rau:
①Degraded beam zoo ntawm cov zis laser
②Txo tag nrho lub zog conversion efficiency
③Ua kom thermal stress thiab txo qhov system lifespan
④Muaj kev pheej hmoo siab ntawm optical puas thaum lub sijhawm ua haujlwm
Yog li ntawd, kev ua tiav qhov sib txawv ntawm qhov sib txawv hauv lub twj tso kua mis lub teeb faib yog lub hom phiaj tseem ceeb hauv kev tsim thiab tsim cov twj tso kua mis module.
2. Feem ntau ua rau kev faib khoom tsis sib xws
①Variations hauv Chip Emission Power
Laser diode chips inherently nthuav tawm lub zog hloov pauv. Yog tias tsis muaj kev txheeb xyuas los yog kev them nyiaj, qhov sib txawv no tuaj yeem ua rau tsis sib haum ntawm lub twj tso kua mis siv nyob rau hauv lub hom phiaj.
②Qhov yuam kev hauv Collimation thiab Focusing Systems
Misalignments lossis flaws nyob rau hauv cov khoom siv kho qhov muag (xws li, FAC / SAC lo ntsiab muag, microlens arrays, fiber ntau txuas) tuaj yeem ua rau qhov chaw ntawm cov nqaj sib txawv ntawm lub hom phiaj, tsim cov hotspots lossis thaj chaw tuag.
③Thermal Gradient Effects
Semiconductor lasers yog rhiab heev rau qhov kub thiab txias. Kev tsim cov cua sov tsis zoo lossis qhov cua txias tsis sib xws tuaj yeem ua rau muaj qhov sib txawv ntawm qhov sib txawv ntawm cov chips sib txawv, cuam tshuam rau kev sib txuas ua haujlwm thiab cov khoom sib xws.
④Tsis txaus Fiber Output Design
Hauv ntau cov tub ntxhais fiber ntau lossis kab teeb sib txuas cov qauv tsim tawm, cov txheej txheem tsis tsim nyog tuaj yeem ua rau lub teeb tsis sib xws hauv lub teeb faib hauv qhov nruab nrab.
3. Cov txheej txheem los txhim kho kom muaj kev sib haum xeeb
①Chip sorting thiab fais fab sib piv
Precisely tshuaj ntsuam thiab pab pawg laser diode chips los xyuas kom meej cov zis muaj zog nyob rau hauv txhua lub module, txo qis hauv zos overheating thiab nce hotspots.
②Optimized Optical Design
Siv cov optics uas tsis yog duab los yog homogenizing lo ntsiab muag (xws li, microlens arrays) los txhim kho kab sib tshooj thiab tsom qhov tseeb, yog li ua kom lub teeb pom kev zoo.
③Txhim kho Thermal Management
Siv cov khoom siv thermal conductivity siab (xws li CuW, CVD pob zeb diamond) thiab cov tswv yim tswj qhov kub thiab txias kom txo cov nti-rau-chip kub hloov pauv thiab tswj cov zis ruaj khov.
④Lub teeb siv homogenization
Muab cov diffusers los yog beam-shaping ntsiab nyob rau hauv lub twj tso kua mis txoj kev mus cuag ib tug ntau txawm spatial faib ntawm lub teeb nyob rau hauv lub nce nruab nrab.
4. Tus nqi tsim nyog hauv kev siv tiag tiag hauv ntiaj teb
Nyob rau hauv high-end laser systems—xws li precision industrial processing, tub rog laser xaiv, kev kho mob, thiab kev tshawb fawb tshawb fawb—lub stability thiab beam zoo ntawm lub laser tso zis yog qhov tseem ceeb. Non-uniform nce kev faib ncaj qha cuam tshuam rau kev ntseeg siab thiab raug, tshwj xeeb hauv cov xwm txheej hauv qab no:
①High-zog pulsed lasers: Tsis txhob muaj qhov saturation hauv zos lossis cov teebmeem uas tsis yog-linear
②Fiber laser amplifiers: Tshem tawm ASE (Amplified Spontaneous Emission) buildup
③LIDAR thiab rangefinding systems: Txhim kho kev ntsuas qhov tseeb thiab rov ua dua
④Kev kho mob lasers: xyuas kom meej lub zog tswj thaum lub sij hawm kho
5. Cov lus xaus
Tau txais kev faib tawm tsis sib xws yuav tsis yog qhov pom pom zoo tshaj plaws ntawm lub twj tso kua mis module, tab sis nws yog qhov tseem ceeb rau kev txhim kho lub zog ua haujlwm siab laser tshuab. Raws li kev xav tau ntawm laser zoo thiab kev ruaj ntseg txuas ntxiv mus, twj tso kua mis module manufacturers yuav tsum kho“kev tswj tsis sib xws”raws li tus txheej txheem tseem ceeb—tas li refining nti xaiv, qauv tsim, thiab thermal cov tswv yim kom xa ntau txhim khu kev qha thiab zoo ib yam laser qhov chaw rau downstream daim ntaub ntawv.
Xav paub seb peb yuav ua li cas kom tau txais kev sib npaug hauv peb cov twj tso kua mis? Tiv tauj peb hnub no kom paub ntau ntxiv txog peb cov kev daws teeb meem thiab kev txhawb nqa.
