1, makampani amasinthasintha ndi kupanga mkombero mu nthawi yochepa, ndi yaitali mosalekeza malowedwe amalimbikitsa kukula sikelo.
(1) Makina opanga ma laser ndi makampani omwe adatchulidwa
Unyolo wamakampani a laser: Kumtunda kwa unyolo wamakampani a laser ndi tchipisi ta laser ndi zida za optoelectronic zopangidwa ndi zida za semiconductor, zida zomaliza ndi zida zofananira zopangira, zomwe ndi mwala wapangodya wamakampani a laser.
Pakati pa unyolo wa mafakitale, tchipisi ta laser kumtunda ndi zida za optoelectronic, ma modules, zigawo za kuwala, ndi zina zotero zimagwiritsidwa ntchito kupanga ndi kugulitsa mitundu yonse ya lasers; Mtsinje wapansi ndi chophatikizira cha zida za laser, zomwe zogulitsa zake zimagwiritsidwa ntchito popanga zapamwamba, thanzi lachipatala, kafukufuku wasayansi, ntchito zamagalimoto, ukadaulo wazidziwitso, kulumikizana kwa kuwala, kusungirako kuwala ndi zina zambiri.
Mbiri yachitukuko chamakampani a laser:
Mu 1917, Einstein anaika patsogolo lingaliro la cheza chosonkhezera, ndipo luso la laser pang’onopang’ono linakula m’lingaliro m’zaka 40 zotsatira;
Mu 1960, woyamba ruby laser anabadwa. Pambuyo pake, mitundu yonse ya lasers idatuluka imodzi pambuyo pa inzake, ndipo makampaniwo adalowa gawo lakukulitsa ntchito;
Pambuyo pa zaka za m'ma 20, makampani a laser adalowa mu gawo lachitukuko chofulumira. Malinga ndi Report on Development of China's Laser Industry, kukula kwa msika wa zida za laser ku China kudakwera kuchoka pa 9.7 biliyoni kufika pa 69.2 biliyoni kuyambira 2010 mpaka 2020, ndi CAGR pafupifupi 21.7%.
(2) Pakanthawi kochepa, zimasinthasintha ndi kayendedwe ka kupanga. M'kupita kwa nthawi, kuchuluka kwa malowedwe kumawonjezeka ndipo ntchito zatsopano zimakula
1. Makampani a laser amafalitsidwa kwambiri kumunsi ndipo amasinthasintha ndi makampani opanga nthawi yochepa
Kulemera kwakanthawi kochepa kwamakampani a laser kumagwirizana kwambiri ndi mafakitale opanga.
Kufunika kwa zida za laser kumachokera ku ndalama zazikulu zamabizinesi akutsika, zomwe zimakhudzidwa ndi kuthekera komanso kufunitsitsa kwa mabizinesi kugwiritsa ntchito ndalama. Zomwe zimakhudzidwa zimaphatikizira phindu lamabizinesi, kugwiritsa ntchito mphamvu, malo azandalama zakunja zamabizinesi, ndi ziyembekezo zamtsogolo zamakampaniwo.
Nthawi yomweyo, zida za laser ndi zida zomwe zimagwiritsidwa ntchito ponseponse, zomwe zimafalitsidwa kwambiri pamagalimoto, zitsulo, mafuta, zomangamanga ndi mafakitale ena kumunsi kwa mtsinje. Kutukuka konse kwamakampani a laser kumagwirizana kwambiri ndi mafakitale opanga.
Potengera kusinthasintha kwambiri kwamakampani, msika wa laser udakula kwambiri kuyambira 2009 mpaka 2010, Q2, 2017, Q1 mpaka 2018, makamaka okhudzana ndi mayendedwe amakampani opanga zinthu komanso kusintha kwazinthu zomaliza.
Pakali pano, mkombero wamakampani opanga zinthu uli pachiwopsezo, malonda a maloboti amakampani, zida zodulira zitsulo, ndi zina zambiri zimakhalabe pamlingo wapamwamba, ndipo makampani a laser ali munthawi yofunikira kwambiri.
2. Kuwonjezeka kwa permeability ndi kuwonjezereka kwatsopano kwa ntchito m'kupita kwanthawi
Laser processing ali ndi ubwino zoonekeratu pokonza Mwachangu ndi khalidwe, ndi kusintha ndi kukweza makampani opanga kulimbikitsa chitukuko cha makampani. Laser processing ndi kuyang'ana laser pa chinthu kuti kukonzedwa, kuti chinthu akhoza kutenthedwa, kusungunuka kapena vaporized, kuti akwaniritse cholinga processing.
Poyerekeza ndi njira zachikhalidwe, laser processing ili ndi maubwino atatu:
(1) The laser processing njira akhoza kulamulidwa ndi mapulogalamu;
(2) The mwatsatanetsatane laser processing ndi apamwamba kwambiri;
(3) Laser processing ndi ya non-contact processing, yomwe ingachepetse kutaya kwa zipangizo zodulira ndipo imakhala ndi khalidwe labwino kwambiri.
Laser processing limasonyeza ubwino zoonekeratu pokonza Mwachangu, processing kwenikweni, etc., ndipo ikugwirizana ndi malangizo onse anzeru kupanga. Kusintha ndi kukweza kwa makampani opanga zinthu kumalimbikitsa m'malo mwa optical processing m'malo mwachikhalidwe.
(3) Ukadaulo wa laser ndi chitukuko chamakampani
Laser luminescence mfundo:
Laser imatanthawuza mtengo wolumikizana, wopangidwa ndi monochromatic komanso wolumikizana womwe umapangidwa ndi mzere wocheperako wa kuwala kwa ma radiation kudzera pakusonkhanitsa mayankho a resonance ndi kukulitsa ma radiation.
Laser ndiye chida chachikulu chopangira laser, chomwe chimapangidwa makamaka ndi magawo atatu: gwero lachisangalalo, sing'anga yogwira ntchito komanso patsekeke. Pogwira ntchito, gwero lachisangalalo limachita pa sing'anga yogwira ntchito, kupanga particles ambiri mu chisangalalo cha msinkhu wa mphamvu, kupanga kutembenuka kwa chiwerengero cha tinthu. Pambuyo pa chochitika cha photon, tinthu tating'onoting'ono tamphamvu timasintha kupita ku mphamvu yochepa, ndipo timatulutsa ma photon ambiri ofanana ndi mafotoni a zochitikazo.
Zithunzi zokhala ndi njira zosiyanasiyana zofalitsira kuchokera kumtunda wopingasa wa pabowo zidzatuluka pabowo, pomwe mafotoni omwe ali ndi njira yomweyi amabwerera m'mphepete, ndikupangitsa kuti ma radiation apitirire ndikupanga matabwa a laser.
Njira yogwirira ntchito:
Zomwe zimatchedwanso gain medium, zimatanthawuza chinthu chomwe chimagwiritsidwa ntchito kuzindikira kusinthika kwa chiwerengero cha tinthu ndikupanga mphamvu yokulitsa mphamvu ya kuwala. Sing'anga yogwirira ntchito imatsimikizira kutalika kwa laser komwe laser imatha kuwunikira. Malingana ndi mawonekedwe osiyanasiyana, amatha kugawidwa kukhala olimba (crystal, galasi), gasi (gasi wa atomiki, gasi ionized, mpweya wa maselo), semiconductor, madzi ndi zina.
Pampu Gwero:
Limbikitsani sing'anga ntchito ndi kupopera adamulowetsa particles kuchokera pansi boma kuti mkulu mphamvu mlingo kuzindikira kutembenuzidwa kwa tinthu nambala. Kuchokera pakuwona mphamvu, njira yopopera ndi njira yomwe dziko lakunja limapereka mphamvu (monga kuwala, magetsi, chemistry, mphamvu ya kutentha, etc.) ku tinthu tating'onoting'ono.
Zitha kugawidwa mu excitation kuwala, mpweya kumaliseche excitation, limagwirira mankhwala, nyukiliya mphamvu excitation, etc.
Resonant cavity:
Chowunikira chosavuta kwambiri chowunikira ndikuyika bwino magalasi awiri owoneka bwino kumapeto onse a sing'anga yogwira, imodzi mwagalasi yokwanira, yomwe ikuwonetsa kuwala konse kumbuyo kwapakati kuti ipitirire kukulitsa; Chinacho ndi chowonetsera pang'ono komanso chowonetsera pang'ono ngati galasi lotulutsa. Malingana ndi malire a mbali akhoza kunyalanyazidwa, resonator imagawidwa kukhala yotseguka, yotsekedwa ndi mpweya wa waveguide.
