Otsatsa zida za refrigeration laser amapindula ndikukula mwachangu kwa ma lasers a UV

Masiku ano, msika wa laser ukulamulidwa ndi ma fiber lasers omwe amaposa ma lasers a UV. Kugwiritsa ntchito kwamafakitale ambiri kumatsimikizira kuti fiber lasers ndiye gawo lalikulu pamsika. Ponena za ma laser a UV, mwina sangakhale othandiza ngati ma laser a fiber m'malo ambiri chifukwa cha malire ake, koma ndi mawonekedwe a 355nm wavelength omwe amasiyanitsa ma lasers a UV ndi ma lasers ena, kupangitsa ma lasers a UV kukhala chisankho choyamba muzapadera zina. mapulogalamu.  

Laser ya UV imatheka poika njira yachitatu yamtundu wa harmonic pa kuwala kwa infuraredi. Ndi gwero la kuwala kozizira ndipo njira yake yopangira imatchedwa kuzizira. Ndi utali waufupi wa mafunde& M'lifupi mwake ndi kuwala kwapamwamba kwambiri, ma laser a UV amatha kukwaniritsa ma micromachining olondola kwambiri popanga malo owoneka bwino a laser ndikusunga Malo ang'onoang'ono Okhudza Kutentha. Mayamwidwe amphamvu kwambiri a ma laser a UV, makamaka mkati mwa mawonekedwe a UV wavelength ndi kugunda kwakufupi, kumapangitsa kuti zidazo zisungunuke mwachangu kwambiri kuti muchepetse Kutentha kwa Zone ndi carbonization. Kuphatikiza apo, malo ocheperako amathandizira kuti ma lasers a UV agwiritsidwe ntchito m'malo olondola komanso ang'onoang'ono. Chifukwa cha Malo ang'onoang'ono Okhudzidwa ndi Kutentha, UV laser processing amagawidwa ngati kuzizira ndipo ndi chimodzi mwazinthu zodziwika bwino za laser UV zomwe zimasiyanitsa ndi ma lasers ena. Laser ya UV imatha kufikira mkati mwazinthuzo, chifukwa imagwira ntchito pamachitidwe azithunzi pakukonza. Kutalika kwa laser kwa UV ndi kwakufupi kuposa mawonekedwe owoneka. Komabe, ndi kutalika kwaufupi kumeneku komwe kumathandizira ma lasers a UV kuti aziyang'ana bwino kwambiri kuti ma laser a UV amatha kuwongolera bwino kwambiri ndikusunga mawonekedwe ake nthawi yomweyo.

Ma lasers a UV amagwiritsidwa ntchito kwambiri polemba zida zamagetsi, kuyika chizindikiro pazida zakunja za zida zoyera zapanyumba, chizindikiro cha tsiku lopanga chakudya.& mankhwala, chikopa, handicraft, nsalu kudula, mankhwala mphira, magalasi chuma, nameplate, zipangizo kulankhulana ndi zina zotero. Kuphatikiza apo, ma laser a UV amathanso kugwiritsidwa ntchito m'malo apamwamba komanso olondola, monga kudula kwa PCB ndi kubowola zoumba.& kulemba. Ndikoyenera kunena kuti EUV ndiye njira yokhayo yopangira laser yomwe imatha kuchita pa 7nm chip ndipo kukhalapo kwake kumapangitsa Lamulo la Moore kukhalabe mpaka lero.

M'zaka ziwiri zapitazi, UV laser msika wakumana ndi chitukuko mofulumira. Chaka cha 2016 chisanafike, katundu wapakhomo wa ma lasers a UV anali osakwana mayunitsi 3000. Komabe, mu 2016, chiwerengerochi chinakwera kwambiri kuposa mayunitsi 6000 ndipo mu 2017, chiwerengerocho chinalumpha kufika pa mayunitsi 9000. Kukula mwachangu kwa msika wa laser wa UV kumabwera chifukwa chakuwonjezeka kwa msika wa ntchito zopangira ma laser a UV. Kuphatikiza apo, mapulogalamu ena omwe anali otsogozedwa ndi ma laser a YAG ndi ma laser CO2 m'mbuyomu tsopano asinthidwa ndi ma UV lasers.

Pali makampani ambiri apakhomo omwe amapanga ndikugulitsa ma laser a UV, kuphatikiza Huaray, Inngu, Bellin, Logan, Maiman, RFH, Inno, DZD Photonics ndi Photonix. Kale mu 2009, zoweta UV laser njira anali atangoyamba kumene, koma tsopano ndi okhwima. Makampani ambiri a laser a UV azindikira kupanga kwakukulu, komwe kumaphwanya ulamuliro wamitundu yakunja pa ma laser olimba amtundu wa UV ndikuchepetsa kwambiri mtengo wamagetsi apanyumba a UV. The kwambiri yafupika mtengo kumabweretsa kutchuka kwambiri UV laser processing, amene amathandiza kusintha zoweta processing mlingo. Komabe, ndikofunikira kunena kuti opanga zapakhomo amayang'ana kwambiri ma laser apakati amphamvu a UV kuyambira 1W-12W. (Huaray wapanga ma lasers a UV oposa 20W.) Ngakhale kuti ma lasers amphamvu kwambiri a UV, opanga pakhomo sangathebe kupanga, kusiya zinthu zakunja.

Ponena za mitundu yakunja, Spectral-Physics, Coherent, Trumpf, AOC, Powerlase ndi IPG ndi omwe amasewera kwambiri m'misika yakunja ya UV laser. Spectral-Physics idapanga ma lasers amphamvu a 60W a UV (M2<1.3) pomwe Powerlase ili ndi DPSS 180W UV lasers(M2<30). Ponena za IPG, malonda ake apachaka amafika pafupifupi RMB miliyoni khumi ndipo ulusi wake wa laser umaposa 50% ya msika wa msika waku China. Ngakhale kuchuluka kwa malonda a ma laser a UV ku China ndi gawo laling'ono pakugulitsa kwake konse poyerekeza ndi ma lasers a fiber, IPG ikuganizabe kuti ma lasers aku China UV adzakhala ndi tsogolo labwino, lomwe limathandizidwa ndi kuchuluka kwa kuchuluka kwa ntchito zamagetsi zamagetsi. ku China. Mu kotala yapitayi, IPG idagulitsa laser ya UV yopitilira $ 1 miliyoni yaku US. IPG ikuyembekeza kupikisana ndi Spectral-Physics yomwe ndi gawo la MKS pagawoli komanso DPSSL yachikhalidwe.

Mwambiri, ngakhale ma lasers a UV sakhala otchuka ngati ma laser a fiber, ma lasers a UV akadali ndi tsogolo labwino pamagwiritsidwe ntchito ndi zofuna za msika, zomwe zitha kuwoneka kuchokera pakuwonjezeka kwakukulu kwa kuchuluka kwa zotumizira m'zaka 2 zapitazi. UV laser processing ndi mphamvu yofunika pamsika wa laser processing. Ndi kutchuka kwa lasers zoweta UV, mpikisano pakati zopangidwa m'nyumba ndi zopangidwa akunja adzakulitsa, zomwe zimapangitsa UV lasers otchuka m'nyumba UV laser processing dera.

Njira yayikulu yama lasers a UV imaphatikizapo kapangidwe ka kabowo ka resonant, kuwongolera kuchulutsa pafupipafupi, kubwezera kutentha kwamkati komanso kuziziritsa. Pankhani yowongolera kuziziritsa, ma lasers amphamvu otsika a UV amatha kuziziritsidwa ndi zida zoziziritsira madzi ndi zida zoziziritsira mpweya ndipo ambiri opanga amatha kugwiritsa ntchito zida zoziziritsira madzi. Ponena za ma laser apakati amphamvu a UV, onse ali ndi zida zozizirira madzi. Chifukwa chake, kufunikira kwa msika komwe kukukula kwa ma lasers a UV kudzakulitsa kufunikira kwa msika wamafuta oziziritsa madzi omwe ndi apadera kwa ma laser a UV. Kutulutsa kokhazikika kwa ma lasers a UV kumafuna kutentha kwamkati kuti kusungidwe mkati mwamitundu ina. Choncho, ponena za kuzizira, kuziziritsa kwamadzi kumakhala kokhazikika komanso kodalirika kuposa kuzizira kwa mpweya.

Monga amadziwika kwa onse, kusinthasintha kwa kutentha kwa madzi kwa chozizira chamadzi kumakhala (ie kuwongolera kutentha sikolondola), kuwononga kwambiri kuwala kudzachitika, zomwe zidzakhudza mtengo wokonza laser ndikufupikitsa moyo wa ma lasers. Komabe, kutentha kwambiri kwa chozizira chamadzi kumakhala kocheperako, kusinthasintha kwamadzi kumakhala kochepa komanso kutulutsa kokhazikika kwa laser kudzachitika. Komanso, khola madzi kuthamanga kwa chiller madzi akhoza kwambiri kuchepetsa chitoliro katundu wa lasers ndi kupewa m'badwo wa kuwira. S&A Teyu madzi ozizira ndi kapangidwe yaying'ono ndi bwino mapaipi kamangidwe angapewe m'badwo wa kuwira ndi kusunga khola linanena bungwe laser, amene amathandiza kutalikitsa moyo ntchito lasers ndi kupulumutsa mtengo kwa owerenga.
