Kuwotcherera ndi njira yolumikiza zitsulo ziwiri kapena zingapo pamodzi pogwiritsa ntchito kutentha. Kuwotcherera nthawi zambiri kumaphatikizapo kutenthetsa zinthu kuti zisungunuke kuti zitsulo zoyambira zisungunuke kudzaza mipata pakati pa mfundozo, kupanga kulumikizana kolimba. Kuwotcherera kwa laser ndi njira yolumikizira yomwe imagwiritsa ntchito laser ngati gwero la kutentha.
Tengani batire ya square kesi yamphamvu monga chitsanzo: batire yoyambira imalumikizidwa ndi laser kudzera magawo angapo. Pa nthawi yonse ya kuwotcherera kwa laser, mphamvu yolumikizira zinthu, mphamvu zopangira, komanso kuchuluka kwapang'onopang'ono ndi zinthu zitatu zomwe makampani akuda nkhawa nazo. Mphamvu yolumikizana ndi zinthu imatha kuwonetsedwa ndi kuya ndi kuzama kwa metallographic (zogwirizana kwambiri ndi gwero la kuwala kwa laser); Mwachangu kupanga makamaka zokhudzana ndi processing mphamvu ya gwero kuwala laser; kuchuluka kwachilema kumakhudzana makamaka ndi kusankha kwa gwero la kuwala kwa laser; chifukwa chake, nkhaniyi ikufotokoza zomwe zimafala pamsika. Kuyerekeza kosavuta kwa magwero angapo a kuwala kwa laser kumachitika, ndikuyembekeza kuthandiza othandizira ena.
Chifukwalaser kuwotchererakwenikweni ndi njira yosinthira kuwala kwa kutentha, magawo angapo ofunikira omwe akukhudzidwa ndi awa: mtengo wamtengo (BBP, M2, divergence angle), kachulukidwe kamphamvu, mainchesi apakati, mawonekedwe ogawa mphamvu, mutu wowotcherera, kukonza mazenera ndi zinthu zosinthika. amagwiritsidwa ntchito makamaka kusanthula ndi kufananiza magwero a kuwala kwa laser kuchokera kumayendedwe awa.

Monga momwe tawonetsera pachithunzichi: Chithunzi b chikuwonetsa kugawa mphamvu kwa njira imodzi yofunikira, ndipo kugawa mphamvu kumbali iliyonse kudutsa pakati pa bwalo kuli ngati mawonekedwe a Gaussian curve. Chithunzi a chikuwonetsa kugawa kwamitundu yambiri, komwe ndi kugawa mphamvu kwapamlengalenga komwe kumapangidwa ndi mawonekedwe apamwamba amitundu ingapo ya laser. Chotsatira cha multi-mode superposition ndi chopindika chapamwamba.
Ma lasers a single-mode: IPG YLR-2000-SM, SM ndiye chidule cha Single Mode. Kuwerengera kumagwiritsa ntchito collimated focus 150-250 kuwerengera kukula kwa malo, mphamvu yamagetsi ndi 2000W, ndipo kachulukidwe ka mphamvu kakugwiritsidwa ntchito kuyerekeza.

Ma semiconductors nthawi zambiri amagwiritsa ntchito kuwala kwakukulu kopitilira 400um, komwe kumayambitsa kutentha kwa zinthuzo, kusungunula pamwamba pa zinthuzo, ndikuwonjezera kuchuluka kwa mayamwidwe a fiber laser (mayamwidwe a laser amachulukira momwe kutentha kumachulukira)
Mphete ya laser: Ma module awiri a fiber laser amatulutsa kuwala kwa laser, komwe kumatumizidwa kuzinthu zakuthupi kudzera mumagulu ophatikizika a ulusi (mphete ya kuwala mkati mwa cylindrical optical fiber).
Miyendo iwiri ya laser yokhala ndi malo a annular: mphete yakunja imayang'anira kukulitsa chibowo cha kiyi ndikusungunula zinthu, ndipo mphete yamkati ya laser imayang'anira kuzama kolowera, ndikupangitsa kuwotcherera kwa spatter kopitilira muyeso. Mphete zamkati ndi zakunja za laser mphamvu zapakati zimatha kufananizidwa momasuka, ndipo mainchesi apakati amatha kufananizidwa momasuka. Zenera la ndondomekoyi ndi losavuta kusintha kusiyana ndi mtengo umodzi wa laser.
