Kuyamba kwa Laser Processing mu Manufacturing
Ukadaulo waukadaulo wa laser wakula mwachangu ndipo umagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana, monga zakuthambo, magalimoto, zamagetsi, ndi zina zambiri.Zimagwira ntchito yofunika kwambiri pakuwongolera zopangira, zokolola za anthu ogwira ntchito, komanso zodzipangira zokha, pomwe zimachepetsa kuipitsidwa ndi kugwiritsa ntchito zinthu (Gong, 2012).
Laser Processing mu Zitsulo ndi Zopanda zitsulo
Kugwiritsa ntchito kwambiri laser processing m'zaka khumi zapitazi kwakhala muzinthu zachitsulo, kuphatikizapo kudula, kuwotcherera, ndi kuphimba.Komabe, gawoli likukulirakulira kukhala zinthu zopanda chitsulo monga nsalu, magalasi, mapulasitiki, ma polima, ndi zoumba.Chilichonse mwazinthu izi chimatsegula mwayi m'mafakitale osiyanasiyana, ngakhale adakhazikitsa kale njira zopangira (Yumoto et al., 2017).
Zovuta ndi Zatsopano mu Laser Processing of Glass
Galasi, yomwe imagwiritsidwa ntchito kwambiri m'mafakitale monga magalimoto, zomangamanga, ndi zamagetsi, imayimira malo ofunikira kwambiri pokonza laser.Njira zachikhalidwe zodulira magalasi, zomwe zimaphatikizapo zida zolimba za aloyi kapena diamondi, zimakhala zocheperako komanso m'mphepete mwazovuta.Mosiyana ndi izi, kudula kwa laser kumapereka njira yabwino komanso yolondola.Izi zikuwonekera makamaka m'mafakitale monga kupanga mafoni a m'manja, komwe kudula kwa laser kumagwiritsidwa ntchito pazovala zamagalasi a kamera ndi zowonera zazikulu (Ding et al., 2019).
Kusintha kwa Laser kwa Mitundu Yamagalasi Yamtengo Wapatali
Mitundu yosiyanasiyana ya magalasi, monga magalasi owoneka bwino, magalasi a quartz, ndi galasi la safiro, amakumana ndi zovuta zapadera chifukwa cha kufooka kwawo.Komabe, njira zapamwamba za laser monga femtosecond laser etching zathandizira kukonzedwa bwino kwa zida izi (Sun & Flores, 2010).
Mphamvu ya Wavelength pa Njira za Laser Technological
Kutalika kwa mafunde a laser kumakhudza kwambiri njirayi, makamaka pazinthu monga zitsulo zamapangidwe.Ma laser otulutsa mu ultraviolet, owoneka, pafupi ndi madera akutali a infrared adawunikidwa chifukwa cha kuchuluka kwawo kwamphamvu kwamphamvu pakusungunuka ndi kutuluka kwa nthunzi (Lazov, Angelov, & Teirumnieks, 2019).
Ntchito Zosiyanasiyana Zotengera Wavelengths
Kusankhidwa kwa laser wavelength sikopanda pake koma kumadalira kwambiri zinthu zakuthupi ndi zotsatira zomwe mukufuna.Mwachitsanzo, ma lasers a UV (okhala ndi mafunde amfupi) ndiabwino kwambiri pakujambula bwino komanso kupanga ma micromachining, chifukwa amatha kupanga zambiri.Izi zimawapangitsa kukhala abwino kwa mafakitale a semiconductor ndi ma microelectronics.Mosiyana ndi izi, ma lasers a infrared ndi othandiza kwambiri pakukonza zinthu zokhuthala chifukwa cha kuthekera kwawo kolowera, kuwapangitsa kukhala oyenera kugwiritsa ntchito mafakitale olemera.(Majumdar & Manna, 2013) .Mofananamo, ma laser obiriwira, omwe amagwira ntchito pamtunda wa 532 nm, amapeza niche yawo pamapulogalamu omwe amafunikira kulondola kwambiri komanso kutentha kochepa.Amagwira ntchito makamaka mu ma microelectronics pa ntchito monga ma circuit patterning, mu ntchito zachipatala zamachitidwe monga photocoagulation, ndi gawo la mphamvu zongowonjezwdwanso popanga ma cell a solar.Kutalika kwapadera kwa ma lasers obiriwira kumawapangitsanso kukhala oyenera kuyika chizindikiro ndi kuzokota zinthu zosiyanasiyana, kuphatikiza mapulasitiki ndi zitsulo, pomwe kusiyanasiyana kwakukulu komanso kuwonongeka pang'ono kumafunika.Kusinthika kwa ma laser obiriwira kumatsimikizira kufunikira kwa kusankha kwa kutalika kwa ukadaulo wa laser, kuwonetsetsa kuti pamakhala zotsatira zabwino pazida zina ndi ntchito.
The525nm wobiriwira laserndi mtundu wina waukadaulo wa laser womwe umadziwika ndi kuwala kwake kobiriwira komwe kumafikira kutalika kwa 525 nanometers.Ma laser obiriwira pamafundewa amapeza ntchito mu retinal photocoagulation, pomwe mphamvu zawo zapamwamba komanso kulondola kwake kumakhala kopindulitsa.Zimakhalanso zothandiza pakukonza zinthu, makamaka m'magawo omwe amafunikira kuwongolera bwino komanso kochepa kwambiri kwa kutentha.Kupanga ma laser diode obiriwira pagawo la ndege la GaN kupita kumtunda wautali pa 524-532 nm kukuwonetsa kupita patsogolo kwaukadaulo wa laser.Kukula kumeneku ndikofunikira pamapulogalamu omwe amafunikira mawonekedwe apadera a kutalika kwa mafunde
Wopitiriza Wave ndi Modelocked Laser Sources
Continuous wave (CW) ndi ma modelocked quasi-CW laser sources pamafunde osiyanasiyana monga pafupi-infrared (NIR) pa 1064 nm, wobiriwira pa 532 nm, ndi ultraviolet (UV) pa 355 nm amaganiziridwa ngati ma cell a laser doping selective emitter solar.Mafunde osiyanasiyana amakhala ndi tanthauzo pakupanga kusinthika komanso kuchita bwino (Patel et al., 2011).
Excimer Lasers kwa Wide Band Gap Zida
Ma laser a Excimer, omwe amagwira ntchito pa UV wavelength, ndi oyenera kukonza zida za bandgap zazikulu ngati galasi ndi kaboni fiber-reinforced polymer (CFRP), zomwe zimapereka kulondola kwambiri komanso kutenthetsa pang'ono (Kobayashi et al., 2017).
Nd: LAG Lasers for Industrial Applications
Ma lasers a Nd:YAG, omwe amatha kusinthasintha malinga ndi kusintha kwa mafunde, amagwiritsidwa ntchito pazinthu zosiyanasiyana.Kukhoza kwawo kugwira ntchito pa 1064 nm ndi 532 nm kumalola kusinthasintha pokonza zinthu zosiyanasiyana.Mwachitsanzo, kutalika kwa kutalika kwa 1064 nm ndikwabwino pakuzokota mozama pazitsulo, pomwe kutalika kwa 532 nm kumapereka zojambula zapamwamba kwambiri pamapulasitiki ndi zitsulo zokutidwa. (Moon et al., 1999).

High Power Fiber Laser Welding
Ma laser okhala ndi kutalika kwa mafunde pafupi ndi 1000 nm, okhala ndi mtengo wabwino komanso mphamvu zambiri, amagwiritsidwa ntchito powotcherera zitsulo za keyhole laser.Ma lasers awa amatulutsa nthunzi bwino ndikusungunula zida, kupanga ma welds apamwamba kwambiri (Salminen, Piili, & Purtonen, 2010).
Kuphatikiza kwa Laser Processing ndi Matekinoloje Ena
Kuphatikizana kwa laser processing ndi matekinoloje ena opanga, monga kuphimba ndi mphero, kwapangitsa kuti pakhale njira zopangira zogwira mtima komanso zosunthika.Kuphatikizana kumeneku kumapindulitsa kwambiri m'mafakitale monga zida ndi kufa ndi kukonza injini (Nowotny et al., 2010).
Kusintha kwa Laser M'magawo Otukuka
Kugwiritsa ntchito ukadaulo wa laser kumafikira madera omwe akubwera ngati semiconductor, mawonedwe, ndi mafakitale ocheperako amafilimu, opatsa mphamvu zatsopano ndikuwongolera zinthu zakuthupi, kulondola kwazinthu, komanso magwiridwe antchito a chipangizo (Hwang et al., 2022).
Tsogolo Latsopano mu Laser Processing
Zotukuka zamtsogolo muukadaulo waukadaulo wa laser zimayang'ana kwambiri njira zopangira zinthu zatsopano, kukonza zinthu, uinjiniya wophatikizika wazinthu zambiri komanso kupititsa patsogolo phindu lazachuma komanso kachitidwe.Izi zikuphatikiza kupanga laser mwachangu kwazinthu zokhala ndi porosity yoyendetsedwa, kuwotcherera kosakanizidwa, ndi kudula mbiri ya laser yama sheet achitsulo (Kukreja et al., 2013).
Ukadaulo waukadaulo wa laser, womwe umagwiritsidwa ntchito mosiyanasiyana komanso zopanga zatsopano, ukupanga tsogolo lazopanga ndi kukonza zinthu.Kusinthasintha kwake komanso kulondola kwake kumapangitsa kuti ikhale chida chofunikira kwambiri m'mafakitale osiyanasiyana, kukankhira malire a njira zachikhalidwe zopangira.
