Ntchito Yowonjezereka ya Kukonza Laser mu Zitsulo, Galasi, ndi Kupitirira

Mphamvu ya Wavelength pa Njira za Ukadaulo wa Laser

Kutalika kwa mafunde a laser kumakhudza kwambiri njirayi, makamaka pazinthu monga chitsulo chomangira. Ma laser omwe amatulutsa mu ultraviolet, malo owoneka, apafupi ndi akutali a infrared afufuzidwa kuti awone kuchuluka kwa mphamvu zawo zofunika pakusungunula ndi kupsa (Lazov, Angelov, & Teirumnieks, 2019).

Ntchito Zosiyanasiyana Zochokera pa Ma Wavelengths

Kusankha kutalika kwa mafunde a laser sikosankha koma kumadalira kwambiri mawonekedwe a chinthucho ndi zotsatira zomwe mukufuna. Mwachitsanzo, ma laser a UV (okhala ndi mafunde afupiafupi) ndi abwino kwambiri pakujambula bwino komanso kupanga ma micromachine, chifukwa amatha kupanga zinthu zabwino kwambiri. Izi zimapangitsa kuti zikhale zoyenera kwambiri m'mafakitale a semiconductor ndi microelectronics. Mosiyana ndi zimenezi, ma laser a infrared ndi othandiza kwambiri pokonza zinthu zokhuthala chifukwa cha mphamvu zawo zolowera kwambiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'mafakitale akuluakulu. (Majumdar & Manna, 2013). Mofananamo, ma laser obiriwira, omwe nthawi zambiri amagwira ntchito pa mafunde a 532 nm, amapeza malo awo ogwiritsira ntchito omwe amafunikira kulondola kwambiri komanso kutentha kochepa. Amagwira ntchito bwino kwambiri mu ma microelectronics pa ntchito monga circuit patterning, mu ntchito zachipatala pa njira monga photocoagulation, komanso mu gawo la mphamvu zongowonjezwdwa popanga ma solar cell. Kutalika kwapadera kwa ma laser obiriwira kumawapangitsanso kukhala oyenera kulemba ndi kujambula zinthu zosiyanasiyana, kuphatikizapo mapulasitiki ndi zitsulo, komwe kusiyana kwakukulu ndi kuwonongeka kochepa kwa pamwamba kumafunika. Kusinthasintha kumeneku kwa ma laser obiriwira kukuwonetsa kufunika kosankha kutalika kwa mafunde muukadaulo wa laser, kuonetsetsa kuti zinthu ndi ntchito zinazake ndi zabwino kwambiri.

TheLaser wobiriwira wa 525nmndi mtundu winawake wa ukadaulo wa laser womwe umadziwika ndi kutulutsa kwake kuwala kobiriwira pa kutalika kwa mafunde a 525 nanometers. Ma laser obiriwira pa kutalika kwa mafunde kumeneku amapeza ntchito mu retina photocoagulation, komwe mphamvu zawo zapamwamba ndi kulondola kwawo zimakhala zothandiza. Amakhalanso othandiza pokonza zinthu, makamaka m'magawo omwe amafunikira kukonza kutentha kolondola komanso kochepa..Kupanga ma diode obiriwira a laser pa c-plane GaN substrate kupita ku ma wavelengths ataliatali pa 524–532 nm kukuwonetsa kupita patsogolo kwakukulu muukadaulo wa laser. Kukula kumeneku ndikofunikira kwambiri pakugwiritsa ntchito komwe kumafuna mawonekedwe enaake a wavelength.

Magwero a Mafunde Osalekeza ndi Magwero a Laser Otsekedwa

Mafunde osalekeza (CW) ndi magwero a laser a quasi-CW okhala ndi mafunde osiyanasiyana monga near-infrared (NIR) pa 1064 nm, wobiriwira pa 532 nm, ndi ultraviolet (UV) pa 355 nm amaganiziridwa kuti agwiritsidwe ntchito ndi ma solar cell osankha ma laser. Mafunde osiyanasiyana ali ndi tanthauzo pakupanga zinthu mosavuta komanso moyenera (Patel et al., 2011).

Ma Laser a Excimer a Zipangizo Zopanda Mzere Waukulu

Ma laser a Excimer, omwe amagwira ntchito pa mafunde a UV, ndi oyenera kukonza zinthu zopingasa monga galasi ndi carbon fiber-reinforced polymer (CFRP), zomwe zimapereka kulondola kwakukulu komanso kutentha kochepa (Kobayashi et al., 2017).

Nd:YAG Lasers ya Mafakitale Ogwiritsira Ntchito

Ma laser a Nd:YAG, omwe amatha kusinthasintha malinga ndi kusintha kwa mafunde, amagwiritsidwa ntchito m'njira zosiyanasiyana. Kutha kwawo kugwira ntchito pa 1064 nm ndi 532 nm kumalola kusinthasintha pokonza zinthu zosiyanasiyana. Mwachitsanzo, mafunde a 1064 nm ndi abwino kwambiri pojambula zinthu mozama pazitsulo, pomwe mafunde a 532 nm amapereka zojambula zapamwamba kwambiri pamwamba pa pulasitiki ndi zitsulo zophimbidwa. (Moon et al., 1999).

→Zogulitsa Zofanana:Laser yolimba yopompedwa ndi diode ya CW yokhala ndi mafunde a 1064nm

Kuwotcherera kwa Laser kwa Mphamvu Yaikulu ya Ulusi

Ma laser okhala ndi mafunde ozungulira pafupifupi 1000 nm, okhala ndi kuwala kwabwino komanso mphamvu zambiri, amagwiritsidwa ntchito powotcherera zitsulo pogwiritsa ntchito laser ya keyhole. Ma laser amenewa amasungunula ndi kusungunula zinthu bwino, ndikupanga ma weld apamwamba (Salminen, Piili, & Purtonen, 2010).

Kuphatikiza kwa Kukonza Laser ndi Maukadaulo Ena

Kuphatikizika kwa njira zopangira laser ndi ukadaulo wina wopanga, monga cladding ndi milling, kwapangitsa kuti pakhale njira zopangira zogwira mtima komanso zosiyanasiyana. Kuphatikiza kumeneku ndikothandiza kwambiri m'mafakitale monga kupanga zida ndi zida zoyeretsera komanso kukonza injini (Nowotny et al., 2010).
