Kusiyana pakati pa kuwala kosalala pamwamba ndi kuwala kwa Gaussian

Mu mphamvu ya laser nthawi zambiri imakhala mtengo wa Gaussian, ndiye kuti, kulimba kwa mtengowo mumlengalenga kumapereka kugawidwa kwa Gaussian, mtengo woterewu umakhala ndi mphamvu yapakatikati kwambiri, ndipo pang'onopang'ono umatsika motsatira njira ya Gaussian kunja.

Muzogwiritsira ntchito, sikuti matabwa a Gaussian amafunikira nthawi zambiri, komanso matabwa a laser pazofuna zinazake.Mwachitsanzo, pakugawa mphamvu, pali kugawa kwa mphete;Pamawonekedwe a mtengo, pali mawonekedwe monga masikweya, ozungulira, etc.

Pankhani yogawa, pali kugawa kwa mphete

Kugawidwa kwa mphamvu kwa mtengo wa Gaussian kumakhala kosagwirizana, ndipo mphamvu yapakati imakhala yochuluka kwambiri, zomwe zidzachititsa kuti kutentha kwa m'deralo kukhale kokwera kwambiri komanso kumakhudza kuyanjana pakati pa laser ndi chinthu;Mphamvu zamapiko awiriwa ndizochepa kwambiri, zomwe zimachepetsa kugwiritsa ntchito.Chifukwa chake, nthawi zina, ndikofunikira kupanga mtengo wa Gaussian kukhala mtengo wathyathyathya wokhala ndi mphamvu yogawa mphamvu kuti muwongolere magwiridwe antchito a laser.

Ziwerengero zotsatirazi zikuwonetsa mawonekedwe a mbiri ya laser ya Gaussian komanso mbiri ya laser yapamwamba:

Magawo otsika kwambiri mbali zonse za gawo lapakati la mtengowo amatchedwa "mapiko awiri" omwe mphamvu yawo ili pansi pa khomo loyaka lomwe limafunikira pakukonza laser, ndipo mphamvu ya mapiko awiriwa nthawi zambiri imawonongeka, zomwe zimapangitsa kuti pakhale vuto lalikulu. kuchepetsa kugwiritsa ntchito mphamvu;Panthawi imodzimodziyo, mphamvu za mapiko awiriwa zidzawononganso malo ozungulira kunja kwa malo omwe akukonzekera, motero kukulitsa malo okhudzidwa ndi kutentha.Kumbali ina, zigawo zamphamvu kwambiri pamwamba pa malo oyaka moto zimatchedwa "mphamvu zowonjezera", ndipo mphamvu zowonjezerazi zimatha kuwononga gawo lapansi;Kuphatikiza apo, mphamvu zapakati ndizokhazikika kwambiri, ndipo ndizosavuta kuwononga ma optics.

Miyendo ya laser ya Flat-top imagwiritsa ntchito mphamvu bwino kuposa matabwa a laser a Gaussian.Mu mbiri ya mtengo wa Gaussian, mphamvu zochulukirapo zomwe zili pakati pazomwe zimafunikira pakugwiritsira ntchito ndi mphamvu pansi pa zomwe zimafunikira m'mapiko onse awiri zimawonongeka.Palibe mapiko pazithunzi zamtengo wapatali, koma pali kusintha kwapamwamba kwambiri, kotero kugwiritsa ntchito mphamvu kumakhala kothandiza kwambiri ndipo kuwonongeka kwa malo ozungulira kumachepetsedwa.

Monga momwe tikuonera pachithunzi pamwambapa, mphamvu ya mtengo wathyathyathya imakhala yodziwika bwino m'dera lomwe laperekedwa kuposa mtengo wa Gaussian.Kuwotcherera kapena kudula ndi mtengo wathyathyathya kudzakhala kolondola komanso kosawononga malo ozungulira.

Podula ndi mtengo wathyathyathya pamwamba, mabala oyeretsera ndi m'mphepete mwake amatha kupanga.

Pamene kuwotcherera ndi mtengo wathyathyathya-pamwamba, mipata mu weld idzakhala yosalala kuposa momwe zimakhalira ndi matabwa a gaussian.

Ndi kuipa kotani kwa matabwa a flattop?

Mosiyana ndi mizati ya Gaussian, mawonekedwe amphamvu amasintha pamene akufalikira mu malo aulere, kotero sizothandiza kufalitsa mtunda wautali.Pakufalikira kwa mtengo wa Gaussian, ngakhale kukula kwa mtengowo kukasintha, ndondomeko ya mtengoyo imakhalabe ya Gaussian.

Nthawi zambiri laser imatulutsa mtengo wa Gaussian, kenako zida zina zowoneka bwino zimafunika kugwiritsidwa ntchito kusintha mawonekedwe ake kuti apeze mtengo wapamwamba.

Ukadaulo wapadera wa HBF wa Guanghui Laser(Kuwala Kwambiri Pamwamba Pamwamba),kudzera mu kuwala CHIKWANGWANI linanena bungwe kuwala lathyathyathya pamwamba kuwala, m'mphepete mwa malo akuthwa, mkulu mphamvu pakhomo, akhoza kusintha mlingo laser magwiritsidwe ntchito mphamvu pamene kuchepetsa kutentha anakhudzidwa zone ndi kuwonongeka, mogwira kusintha laser processing liwiro ndi kulondola.

Kutengera chitsanzo cha 5M-12000W laser ya Guanghui Laser, poyerekeza ndi ma lasers ena omwe ali mu gulu lamphamvu lomwelo, kuchuluka kwa mphamvu yogwiritsira ntchito mphamvu kumatha kusintha kwambiri, ndipo mawonekedwe owoneka bwino ndikuti kuthamanga kwachangu kumachulukira kwambiri.

Mukadula mbale zokhuthala (oxygen kudula 16mm zitsulo za kaboni zomwe zikuwonetsedwa pachithunzichi), kudula kwapamwamba kwapamwamba pogwiritsa ntchito ukadaulo wa HBF ndikosavuta ndipo m'mphepete mwake ndi chakuthwa kuposa malo a Gaussian.

Gaussian ndi nsonga zathyathyathya ndizofunikira kwambiri pamtengo wa laser, ndipo mutatha kumvetsetsa kusiyana kwawo, amatha kusankhidwa molingana ndi kusiyana kumeneku pakukonzanso laser.
