Kukula Udindo Wakukonza Laser mu Zitsulo, Galasi, ndi Kupitilira

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, komwe kumafunikira kusiyanitsa kwakukulu komanso kuwonongeka pang'ono pamtunda. Kusinthika kwa ma lasers obiriwira kumatsimikizira kufunikira kwa kusankha kwa kutalika kwa ukadaulo wa laser, kuwonetsetsa kuti zinthu zikuyenda bwino pazinthu zinazake ndikugwiritsa 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).

→Zogwirizana nazo:CW Diode-pumped solid-state laser yokhala ndi kutalika kwa 1064nm

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).
