IiLasers ziye zaba yinto ebalulekileyo kwizicelo zokhuselo, zibonelela ngezakhono ezinokuthi izixhobo zemveli zingakwazi ukuhambelana. Le bhlog iphonononga ukubaluleka kweelaser kukhuselo, igxininisa ukuguquguquka kwazo, ukuchaneka, kunye nenkqubela phambili yetekhnoloji eyenze ilitye lembombo leqhinga langoku lomkhosi.
Intshayelelo
Ukuqaliswa kobuchwephesha belaser kuguqule amacandelo amaninzi, kubandakanywa unxibelelwano, amayeza, kwaye ngokukodwa, ukhuselo. I-Lasers, kunye neempawu zabo ezizodwa zokuhambelana, i-monochromaticity, kunye nobukhulu obuphezulu, zivule imilinganiselo emitsha kwizakhono zasemkhosini, zibonelela ngokuchaneka, ubuqili, kunye nokuguquguquka okubaluleke kakhulu kwimfazwe yanamhlanje kunye nezicwangciso zokukhusela.
Ukuchaneka nokuchaneka
IiLasers zidume ngokuchaneka nokuchaneka kwazo. Ukukwazi kwabo ukugxila kwiithagethi ezincinci kumgama omkhulu kubenza babaluleke kakhulu kwizicelo ezinje ngokuchongwa okujoliswe kuko kunye nesikhokelo somjukujelwa. Iinkqubo zokujolisa kwi-laser ezikumgangatho ophezulu ziqinisekisa ukuhanjiswa okuchanekileyo kwezixhobo, ukunciphisa kakhulu umonakalo owenziweyo kunye nokuphucula amazinga okuphumelela kubuthunywa (Ahmed, Mohsin, & Ali, 2020).
Ukuguquguquka kuzo zonke iiPlatform
Ukulungelelaniswa kwe-lasers kuwo wonke amaqonga ahlukeneyo - ukusuka kwizixhobo eziphathwayo ukuya kwiinkqubo ezinkulu ezixhonywe kwisithuthi - kugxininisa ukuguquguquka kwazo. I-Lasers idibaniswe ngempumelelo kwiiplatifomu zomhlaba, ze-naval, kunye ne-aerial, zikhonza iindima ezininzi ezibandakanya ukuphinda ziqwalaselwe, ukufunyanwa okujoliswe kuyo, kunye nezixhobo zamandla ezithe ngqo ngeenjongo zokuhlasela kunye nokukhusela. Ubungakanani babo be-compact kunye nokukwazi ukulungelelaniswa kwizicelo ezithile zenza i-laser ibe yinto eguquguqukayo kwimisebenzi yokukhusela (Bernatskyi & Sokolovskyi, 2022).
Unxibelelwano olomeleziweyo kunye nokuBeka iliso
Iinkqubo zonxibelelwano ezisekelwe kwiLaser zibonelela ngeendlela ezikhuselekileyo nezisebenzayo zokudlulisa ulwazi, olubalulekileyo kwimisebenzi yasemkhosini. Ithuba eliphantsi lokuthintela kunye nokufumanisa unxibelelwano lwe-laser luqinisekisa ukhuseleko, utshintshiselwano lwedatha yexesha langempela phakathi kweeyunithi, ukwandisa ulwazi lwemeko kunye nokulungelelaniswa. Ngaphaya koko, iilaser zidlala indima ebalulekileyo kucupho kunye nokuphinda ziqwalaselwe, zibonelela ngesombululo ephezulu yokufumana ukuqokelelwa kobukrelekrele ngaphandle kokubhaqwa (Liu et al., 2020).
Izixhobo zaMandla eziNgqongileyo
Mhlawumbi esona sicelo sibalulekileyo selaser kukhuselo sisixhobo samandla esilawulwayo (DEWs). I-Lasers inokuhambisa amandla agxininisiweyo kwithagethi yokuyonakalisa okanye ukuyitshabalalisa, inika amandla oqhankqalazo oluchanekileyo kunye nomonakalo omncinci wokubambisa. Ukuphuhliswa kweenkqubo ze-laser ezinamandla kakhulu zokukhusela imijukujelwa, ukutshatyalaliswa kwedrone, kunye nokukhubazeka kwezithuthi kubonisa amandla e-laser ukutshintsha i-landscape yokuzibandakanya emkhosini. Ezi nkqubo zibonelela ngeenzuzo ezibalulekileyo ngaphezu kwezixhobo zendabuko, kubandakanywa nesantya sokuhanjiswa kokukhanya, iindleko eziphantsi zokudubula, kunye nokukwazi ukubandakanya iithagethi ezininzi ngokuchaneka okuphezulu (Zediker, 2022).
Kwizicelo zokhuselo, iintlobo ngeentlobo ze-laser ziyasetyenziswa, nganye isebenzela iinjongo ezahlukeneyo zokusebenza ngokusekwe kwiipropathi zazo ezizodwa kunye nobuchule. Nazi ezinye zeentlobo ezisetyenziswayo ezisetyenziswayo zelases kwizicelo zokhuselo:
Iintlobo zeLaser ezisetyenziswa kwiNdawo yoKhuselo
IiLaser zelizwe eliSolid (SSLs): Ezi lasers zisebenzisa i-slid gain medium, njengeglasi okanye imathiriyeli yecrystalline efakwe izinto ezinqabileyo zomhlaba. Ii-SSL zisetyenziswa kakhulu kwizixhobo zelaser ezinamandla aphezulu ngenxa yamandla azo aphumayo aphezulu, ukusebenza kakuhle, kunye nomgangatho womqadi. Ziyavavanywa kwaye zisetyenziselwe ukukhusela i-missile, ukutshatyalaliswa kwe-drone, kunye nezinye izicelo zezixhobo zamandla ezithe ngqo (Hecht, 2019).
IFayibha Lasers: I-Fiber lasers isebenzisa i-doped optical fiber njengendlela yokuzuza, inika iingenelo malunga nokuguquguquka, umgangatho we-beam, kunye nokusebenza kakuhle. Zinomtsalane ngakumbi kukhuseleko ngenxa yokubumbana kwazo, ukuthembeka, kunye nokulula kolawulo lobushushu. I-Fiber lasers isetyenziswe kwizicelo ezahlukeneyo zomkhosi, kubandakanywa izixhobo zamandla ezijoliswe kumandla aphezulu, ukutyunjwa okujoliswe kuyo, kunye neenkqubo zokumelana nokulinganisa (Lazov, Teirumnieks, & Ghalot, 2021).
IiLaser zeMichiza: Iilaser zemichiza zivelisa ukukhanya kwelaser ngokusabela kweekhemikhali. Enye yezona zixhobo ze-laser zemichiza eyaziwayo ekukhuseleni yi-Chemical Oxygen Iodine Laser (COIL), esetyenziswa kwiinkqubo ze-laser emoyeni zokukhusela imijukujelwa. Ezi lasers zinokufikelela kumanqanaba aphezulu kakhulu kwaye zisebenza kwimigama emide (Ahmed, Mohsin, & Ali, 2020).
IiLaser zeSemiconductor:Ekwaziwa ngokuba zii-laser diode, ezi zii-laser ezixineneyo nezisebenzayo ezisetyenziswa kuluhlu lwezicelo ukusuka kwii-rangefinders kunye nabaqulunqi abathagethiweyo ukuya kumanyathelo achasene ne-infrared kunye nemithombo yempompo yezinye iinkqubo zelaser. Ubungakanani babo obuncinci kunye nokusebenza kakuhle kubenza bafaneleke kwiinkqubo zokukhusela eziphathekayo kunye nezithuthi (Neukum et al., 2022).
IiLaser eziMithayo kwiCavity Surface-Emitting (VCSELs): Ii-VCSEL zikhupha i-laser light perpendicular to the surface of fabricated wafer kwaye zisetyenziswe kwizicelo ezifuna ukusetyenziswa kwamandla aphantsi kunye ne-compact form factor, njengeenkqubo zonxibelelwano kunye neenzwa zezicelo zokukhusela (Arafin & Jung, 2019).
IiLaser eziBlue:Itekhnoloji yelaser eluhlaza iphononongwa kwizicelo zokhuselo ngenxa yeempawu zayo eziphuculweyo zokufunxa, ezinokunciphisa amandla elaser afunekayo ekujoliswe kuko. Oku kwenza iilaser eziluhlaza zibe ngabaviwa abanokuthi bakhuseleke kwidrone kunye nokukhusela imijukujelwa ye-hypersonic, enika ithuba leenkqubo ezincinci nezikhaphukhaphu ezineziphumo ezisebenzayo (Zediker, 2022).
