Fa'asoa ile matou Fa'asalalauga Fa'aagafesootai Mo Fa'amatalaga Fa'anatinati
Folasaga i le Laser Processing i le gaosiga
Fa'atekonolosi fa'aogaina leisa ua o'o i le fa'avavevave o le atina'e ma fa'aaogaina lautele i vaega eseese, e pei o le va'alele, ta'avale, mea tau eletise, ma isi mea.E iai sona sao taua i le faʻaleleia atili o le lelei o oloa, gaosiga o tagata faigaluega, ma le masini, aʻo faʻaitiitia le faʻaleagaina ma le faʻaaogaina o meafaitino (Gong, 2012).
Fa'agasologa leisa i mea uamea ma mea e le fa'ameamea
O le faʻaaogaina muamua o le faʻaogaina o le laser i le sefulu tausaga talu ai o loʻo i totonu o mea uʻamea, e aofia ai le tipiina, uʻamea, ma le faʻapipiʻiina.Ae ui i lea, o loʻo faʻalauteleina le fanua i mea e le o ni uʻamea e pei o ie, tioata, palasitika, polymers, ma ceramics.O nei mea taʻitasi e tatalaina avanoa i pisinisi eseese, e ui lava ua uma ona latou faʻavaeina metotia faʻaogaina (Yumoto et al., 2017).
Lu'itau ma Fa'afouga i le Laser Processing of Glass
Glass, faʻatasi ai ma ana faʻaoga lautele i pisinisi e pei o taʻavale, faufale, ma mea tau eletise, o loʻo faʻatusalia ai se vaega taua mo le gaosiga o le laser.O auala tipi tioata masani, e aofia ai mea faʻapipiʻi malo poʻo ni taimane, e faʻatapulaʻaina i le maualalo o le lelei ma le talatala pito.I le faʻatusatusaga, o le tipiina o le laser e ofoina atu se isi mea e sili atu ona lelei ma saʻo.O lenei mea e faʻamaonia faapitoa i pisinisi e pei o le telefoni feaveaʻi, lea e faʻaaogaina ai le tipiina o le laser mo tioata tioata ma faʻaaliga tetele (Ding et al., 2019).
Fa'agasologa leisa o Ituaiga Mata'eta'e Maualuluga
O ituaiga tioata eseese, e pei o tioata mata, tioata quartz, ma tioata safaira, o loʻo iai ni luʻitau tulaga ese ona o lo latou natura maʻaleʻale.Ae ui i lea, o auala faʻapitoa e pei o le femtosecond laser etching ua mafai ai ona faʻatautaia saʻo o nei mea (Sun & Flores, 2010).
A'afiaga ole Umi ole Galu ile Fa'agasologa Fa'atekonolosi Laser
O le umi o le galu o le laser e matua aʻafia ai le faagasologa, aemaise lava mo mea e pei o le sila.Lasers e fa'aosoina i le ultraviolet, va'aia, latalata ma mamao mea infrared ua mae'a su'esu'eina mo lo latou malosi malosi mo le liusuavai ma le fa'asao (Lazov, Angelov, & Teirumnieks, 2019).
Fa'aaogāga 'ese'ese Fa'atatau ile Umi ole galu
Ole filifiliga ole umi ole galu ole leisa e le fa'asa'oloto ae e fa'alagolago tele i meafaitino ma mea e mana'omia.Mo se faʻataʻitaʻiga, o laisa UV (faʻatasi ai ma galu pupuu) e sili ona lelei mo le togitogiga saʻo ma le micromachining, aua e mafai ona latou maua ni faʻamatalaga sili atu.O le mea lea e lelei ai mo le semiconductor ma microelectronics alamanuia.I le faʻatusatusaga, o lasers infrared e sili atu ona lelei mo le gaosiga o meafaitino mafiafia ona o lo latou malosi faʻapipiʻi loloto, ma faʻaogaina ai mo galuega mamafa tau alamanuia.(Majumdar & Manna, 2013) E faapena foi, lasers lanu meamata, e masani ona galue i le galu o le 532 nm, maua a latou niche i talosaga e manaʻomia ai le saʻo maualuga ma le itiiti o le aʻafiaga o le vevela.E sili ona aoga i microelectronics mo galuega e pei o le mamanu o le matagaluega, i talosaga faafomaʻi mo taualumaga e pei o le photocoagulation, ma le vaega o le malosi faʻafouina mo le gaosiga o le la.Green lasers 'tulaga umi galu e talafeagai foi mo le maka ma togitogiga o mea eseese, e aofia ai palasitika ma metals, lea e manaomia ai le eseesega maualuga ma le itiiti o le faaleagaina luga.O lenei fetuutuunai o lasers lanu meamata o loʻo faʻamamafaina ai le taua o le filifiliga o le galu i tekinolosi laser, faʻamautinoaina taunuʻuga sili ona lelei mo mea faʻapitoa ma faʻaoga.
O le525nm leisa lanu meamatao se ituaiga faapitoa o tekinolosi leisa o loʻo faʻaalia e lona faʻamalama lanu meamata manino i le galu o le 525 nanometers.Lasers lanumeamata i lenei galu umi e maua ai talosaga i le retinal photocoagulation, lea e aoga ai lo latou malosi maualuga ma le saʻo.E mafai fo'i ona fa'aogaina i le gaosiga o meafaitino, aemaise lava i fanua e mana'omia ai le sa'o ma le la'ititi o a'afiaga o le vevela.O le atinaʻeina o diodes leisa lanumeamata i luga o le c-vaalele GaN substrate agai atu i galu uumi i le 524-532 nm e faʻailogaina ai se alualu i luma taua i tekinolosi laser.O lenei atinaʻe e taua tele mo faʻaoga e manaʻomia ai uiga faʻapitoa ole umi ole galu
Galu Fa'aauau ma Fa'ata'ita'iga Laser Puna
Fa'aauau pea galu (CW) ma modelcked quasi-CW puna leisa i galu eseese e pei o latalata-infrared (NIR) i le 1064 nm, lanu meamata i le 532 nm, ma le ultraviolet (UV) i le 355 nm ua manatu mo leisa doping filifili emitter solar sela.O galu eseese e iai aʻafiaga mo le gaosiga o fetuunaiga ma le lelei (Patel et al., 2011).
Lasers Excimer mo Mea Fa'atagata Lautele Gap
Excimer lasers, o loʻo faʻaogaina i le umi o le galu o le UV, e talafeagai mo le faʻaogaina o mea lautele-bandgap e pei o le tioata ma le carbon fiber-reinforced polymer (CFRP), e ofoina atu le maualuga maualuga ma le itiiti o le aʻafiaga o le vevela (Kobayashi et al., 2017).
Nd: YAG Lasers mo Talosaga Alamanuia
Nd: YAG lasers, faʻatasi ai ma lo latou fetuutuunaʻi i tulaga o le faʻalogo umi, e faʻaaogaina i le tele o faʻaoga.O lo latou gafatia e faʻaogaina i le 1064 nm ma le 532 nm e mafai ai ona fetuunai i le gaosiga o mea eseese.Mo se faʻataʻitaʻiga, o le 1064 nm wavelength e lelei mo le togitogiga loloto i luga o metala, ae o le 532 nm wavelength e maua ai le maualuga o le togitogiga i luga o palasitika ma uʻamea ufiufi. (Moon et al., 1999).

Uilaina leisa Fiber malosi maualuga
Lasers ma galu umi e latalata i le 1000 nm, o loʻo i ai le lelei o le laʻau lelei ma le malosi maualuga, o loʻo faʻaaogaina i le uelo laser keyhole mo metala.O nei lasers e faʻafefe lelei ma faʻafefeteina meafaitino, e maua ai le maualuga o le lelei (Salminen, Piili, & Purtonen, 2010).
Tu'ufa'atasiga o le Laser Processing ma Isi Tekonolosi
O le tuʻufaʻatasia o le faʻaogaina o le laser ma isi tekinolosi gaosiga, e pei o le faʻapipiʻiina ma le viliina, ua taʻitaʻia ai le sili atu ona lelei ma faʻaogaina faiga gaosiga.O lenei tu'ufa'atasiga e sili ona aoga i alamanuia e pei o mea faigaluega ma oti gaosiga ma fa'aleleia afi (Nowotny et al., 2010).
Fa'agasologa o le Laser i Fa'ato'aga Fa'atupu
O le faʻaaogaina o tekonolosi laser e faʻalautele atu i faʻalapotopotoga faʻapitoa e pei o semiconductor, faʻaaliga, ma fale tifaga manifinifi, ofoina atu gafatia fou ma faʻaleleia meafaitino, saʻo oloa, ma le faʻatinoga o masini (Hwang et al., 2022).
Fua'iga i le Lumana'i i Fa'agaioiina Laser
O atina'e i le lumana'i i tekinolosi fa'aogaina leisa o lo'o taula'i i faiga fa'afou fou, fa'aleleia o uiga lelei o oloa, inisinia tu'ufa'atasia vaega tele-meafaitino ma fa'aleleia atili le tamaoaiga ma fa'atinoga.E aofia ai leisa le gaosiga vave o fausaga e pulea porosity, uelo hybrid, ma leisa profile tipiina o pepa uamea (Kukreja et al., 2013).
Fa'atekonolosi fa'agasologa o le laser, fa'atasi ai ma ana fa'aoga eseese ma fa'aauauina fa'afouga, o lo'o fa'atulagaina le lumana'i o le gaosiga ma le gaosiga o meafaitino.O lona agavaʻa ma le saʻo e avea o se meafaigaluega taua tele i pisinisi eseese, tuleia tuaoi o metotia gaosiga masani.
