Nhanganyaya yeLaser Processing muKugadzira
Laser processing tekinoroji yakasangana nekukurumidza uye inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana, senge aerospace, mota, zvemagetsi, nezvimwe.Inobata basa rakakosha mukuvandudza mhando yechigadzirwa, kugadzirwa kwevashandi, uye otomatiki, uku ichideredza kusvibiswa uye kushandiswa kwezvinhu (Gong, 2012).
Laser Processing muSimbi uye Zvisiri-simbi Zvishandiso
Iko kushandiswa kwekutanga kwelaser processing mumakore gumi apfuura kwave mune simbi zvinhu, zvinosanganisira kucheka, welding, uye kupfekedza.Nekudaro, munda uri kuwedzera kuita zvisiri-simbi zvinhu semachira, girazi, mapurasitiki, mapolymers, uye ceramics.Chimwe nechimwe chezvishandiso izvi chinovhura mikana mumaindasitiri akasiyana siyana, kunyangwe ivo vakatogadzira nzira dzekugadzirisa (Yumoto et al., 2017).
Matambudziko uye Innovations muLaser Processing yeGirazi
Girazi, rine mashandisirwo ayo akafara mumaindasitiri akaita semotokari, kuvaka, uye zvemagetsi, inomiririra nzvimbo yakakosha yekugadziriswa kwelaser.Maitiro echinyakare ekucheka magirazi, ayo anosanganisira yakaoma alloy kana madhaimani maturusi, anoganhurirwa nekushomeka kwekuita uye mipendero yakaoma.Kusiyana neizvi, laser kucheka kunopa imwe inoshanda uye yakanyatsoita imwe nzira.Izvi zvinonyanya kuoneka mumaindasitiri akaita sekugadzira smartphone, uko kucheka kwelaser kunoshandiswa kumakamera lens mavhavha uye makuru ekuratidzira skrini (Ding et al., 2019).
Laser Processing Yepamusoro-Kukosha Girazi Mhando
Mhando dzakasiyana dzegirazi, dzakadai segirazi remaziso, girazi requartz, uye girazi resafire, zvinopa matambudziko akasiyana nekuda kwehunhu hwawo hwakaoma.Nekudaro, nzira dzepamberi dzelaser senge femtosecond laser etching dzakagonesa kunyatsogadziriswa kwezvinhu izvi (Zuva & Flores, 2010).
Kufurira kweWavelength paLaser Technological process
Iyo wavelength yelaser inonyanya kupesvedzera maitiro, kunyanya kune zvinhu zvakaita sesimbi yekugadzira.MaLaser anobuda muultraviolet, anooneka, ari padyo uye ari kure infrared nzvimbo akaongororwa nekuda kwesimba rawo rakakosha density yekunyunguduka uye kubuda (Lazov, Angelov, & Teirumnieks, 2019).
Zvishandiso zvakasiyana-siyana zvinoenderana neWavelengths
Sarudzo yelaser wavelength haisi yekupokana asi inotsamira zvakanyanya pazvinhu zvezvinhu uye mhedzisiro inodiwa.Semuyenzaniso, UV lasers (ane mapfupi wavelengths) akanakira kunyora chaiko uye micromachining, sezvo achigona kuburitsa yakatsetseka.Izvi zvinovaita vakanaka kune semiconductor uye microelectronics maindasitiri.Kusiyana neizvi, infrared lasers inoshanda zvakanyanya kune yakakora kugadzirwa kwezvinhu nekuda kwekudzika kwekupinda kwayo, ichiita kuti ive yakakodzera kune inorema maindasitiri kunyorera.(Majumdar & Manna, 2013) .Saizvozvowo, malaser egirinhi, anowanzo shanda paavelength ye532 nm, anowana niche yawo mumaapplication anoda kurongeka kwepamusoro ane kushomeka kwemafuta.Iwo anonyanya kushanda mune mamicroelectronics emabasa akaita sedunhu patani, mune zvekurapa zvikumbiro zvemaitiro senge photocoagulation, uye mune inovandudzwa simba chikamu chekugadzira solar cell.Green lasers 'yakasarudzika wavelength zvakare inoita kuti ive yakakodzera kumaka uye kunyora zvakasiyana zvinhu, zvinosanganisira mapurasitiki nesimbi, uko kusiyanisa kwakanyanya uye kushoma kwekukuvara kwepasi kunodiwa.Uku kuchinjika kwegirinhi lasers kunosimbisa kukosha kwekusarudzwa kwewavelength mune laser tekinoroji, kuve nechokwadi chemhedzisiro yezvakakwana zvezvinhu zvakanangana nemashandisirwo.
The525nm green laserimhando chaiyo yelaser tekinoroji inoratidzwa neyakajeka girinhi mwenje kuburitsa pawavelength ye525 nanometers.Green lasers pane iyi wavelength inowana maapplication mune retinal photocoagulation, uko simba ravo repamusoro uye nemazvo zvinobatsira.Iwo zvakare anogona kubatsira mukugadzirisa zvinhu, kunyanya muminda inoda chaiyo uye kushoma kwemafuta kukanganisa kugadzirisa.Kuvandudzwa kwegirinhi laser diode pane c-ndege GaN substrate yakananga kureba wavelengths pa524-532 nm inoratidza kufambira mberi kwakakosha muhunyanzvi hwelaser.Iyi budiriro yakakosha kune maapplication anoda chaiwo wavelength maitiro
Inoenderera Wave uye Modelocked Laser Sources
Inoenderera mberi wave (CW) uye modelocked quasi-CW laser masosi payakasiyana wavelengths senge padhuze-infrared (NIR) pa1064 nm, girini pa532 nm, uye ultraviolet (UV) pa355 nm inoonekwa seye laser doping inosarudza emitter solar maseru.Yakasiyana wavelengths ine zvazvinoreva pakugadzira kuchinjika uye kugona (Patel et al., 2011).
Excimer Lasers yeWide Band Gap Materials
Excimer lasers, inoshanda paUV wavelength, inokodzera kugadzirisa yakakura-bandgap zvinhu segirazi uye kabhoni fiber-yakasimbiswa polymer (CFRP), ichipa yakanyanya kurongeka uye kushoma kwemafuta ekupisa (Kobayashi et al., 2017).
Nd: YAG Lasers yeMaindasitiri Zvikumbiro
Nd: YAG lasers, nekuchinjika kwavo maererano newavelength tuning, inoshandiswa mumhando dzakasiyana dzekushandisa.Kugona kwavo kushanda pa 1064 nm uye 532 nm inobvumira kushanduka mukugadzirisa zvinhu zvakasiyana.Semuyenzaniso, 1064 nm wavelength yakanakira kunyora kwakadzika pasimbi, nepo 532 nm wavelength inopa yepamusoro-soro pepamusoro pekunyora pamapurasitiki nesimbi dzakavharwa. (Mwedzi et al., 1999).

High Power Fiber Laser Welding
Laser ane wavelengths padyo ne1000 nm, ane yakanaka danda mhando uye yakakwirira simba, anoshandiswa mu keyhole laser welding yesimbi.Aya lasers anonyatso vaporize uye anonyungudika zvinhu, achigadzira emhando yepamusoro welds (Salminen, Piili, & Purtonen, 2010).
Kubatanidzwa kweLaser Processing nemamwe Tekinoroji
Iko kubatanidzwa kwelaser processing nemamwe matekinoroji ekugadzira, senge cladding uye kugaya, kwatungamira kune mamwe anoshanda uye anoshanda akasiyana masisitimu ekugadzira.Kubatanidzwa uku kunonyanya kubatsira mumaindasitiri akadai sechishandiso uye kufa kugadzira uye kugadzirisa injini (Nowotny et al., 2010).
Laser Processing mune Emerging Fields
Iko kushandiswa kwelaser tekinoroji kunosvika kuminda iri kusimukira semiconductor, kuratidza, uye maindasitiri akaonda emafirimu, achipa hunyanzvi hutsva nekuvandudza zvivakwa zvezvinhu, kunyatsoita chigadzirwa, uye kuita kwechishandiso (Hwang et al., 2022).
Ramangwana Trends muLaser Processing
Kubudirira kweramangwana mulaser processing tekinoroji yakanangana nehunyanzvi hwekugadzira hunyanzvi, kuvandudza hunhu hwechigadzirwa, huinjiniya hwakabatanidzwa hwakawanda-zvinhu zvinhu uye kusimudzira hupfumi uye maitiro mabhenefiti.Izvi zvinosanganisira laser kukurumidza kugadzirwa kwezvivakwa zvine inodzorwa porosity, hybrid welding, uye laser mbiri yekucheka kwesimbi mapepa (Kukreja et al., 2013).
Laser yekugadzirisa tekinoroji, ine akasiyana mashandisiro uye inoenderera mberi hunyanzvi, iri kuumba ramangwana rekugadzira uye kugadzirisa zvinhu.Kusarudzika kwayo uye kurongeka kunoita kuti ive chishandiso chakakosha mumaindasitiri akasiyana, ichisundira miganhu yemaitiro echinyakare ekugadzira.
