I-Laser ineempawu ezine eziphambili, ezizezi, ukuqaqamba okuphezulu, ukwalathiswa kakuhle, i-monochromaticity elungileyo, kunye nokuhambelana okuphezulu.Ezi zakhiwo zihambelana nomnye, okwenza i-laser ifaneleke kwiimeko ezahlukeneyo.
Ukukhanya okuphezulu kwelaser luphawu olubalulekileyo olwahlukileyo kwimithombo yokukhanya eqhelekileyo, kwaye ukwandisa amandla kunye nokuqaqamba kwakhona sisihloko sanaphakade sophuhliso lwelaser.Yintoni ukukhanya okuphezulu, okuchazwe ngolwimi lobugcisa kukuba ukusondela kwi-1 yisalathisi M2 esichaza umgangatho we-beam.
Kwiminyaka yakutshanje, ngokuphuculwa kobuchwepheshe, iilaser zefiber zasekhaya ziye zaqhawuka kancinci kancinci kumda wamandla, ukusuka kwi-12KW ukuya kwi-20KW.Okwangoku, i-laser ephezulu yefayibha enamandla angama-30KW iye yasungulwa kwimarike, kwaye inyathelo elilandelayo yi-50KW.Wonke umntu unika ingqwalasela kwaye akhuphisane nokuba amandla e-laser aphuma phezulu, kodwa ngoyaba ukuba ngubani onomgangatho ongcono we-beam.
Namhlanje makhe sijonge ukuba yintoni ukukhanya okuphezulu, kunye neenzuzo kunye nokubaluleka kokukhanya okuphezulu.
Iipropati ze-laser beam
Ukukhanya kwe-laser okukhutshwa yi-laser kujongeka ngolu hlobo, kuqala kuguqukela kwintsimi ekufutshane, emva koko kusasazeka kwintsimi ekude.
ngaphakathi,
Iradiyasi esinqeni se-w0 yiradiyasi apho umqa welaser udibana khona ukuya kwelona candelo lincinane kwibala elikufutshane;
I-Rayleigh ubude be-ZR yindawo xa isinqe se-beam sandiswe ngamaxesha angama-√2;
Intsimi ekude ichazwa njengoluhlu olungaphaya kwamaxesha e-4 ubude beRayleigh, kwaye intsimi ekufutshane ichazwa njengoluhlu ngaphakathi kwamaxesha e-4 ubude beRayleigh;
I-angle ye-divergence angle θ imele iqondo lokuhlukana kwe-laser beam kwintsimi ekude.
Ubume boMgangatho weBeam
Umgangatho we-beam yiparameter engundoqo yokubonakalisa iimpawu ze-laser beam, kwaye sisalathisi esibalulekileyo se-laser, esetyenziselwa ukulinganisa iqondo lokugxila kwi-laser beam kwimeko ethile.Iindlela eziqhelekileyo ezisetyenziselwa ukulinganisa umgangatho we-beam zezi: imveliso yepharamitha ye-beam (BPP) kunye ne-M2into.
I-BPP (iMveliso yeParameter yeBeam): imveliso yepharamitha ye-beam, ichazwa njengeradiyo yesinqe esinqeni (w0) iphindaphindwe nge-engile yokwahlukana kwentsimi ekude (θ):
M2: Umlinganiselo wemveliso yeparamitha yeparamitha kwimveliso yeparamitha yesiseko se-Gaussian beam, enokuguqulwa ibe yi-BPP:
Ukusuka kwifomula engentla, sinokufumanisa lula ukuba: I-BPP ayinanto yakwenza nobude bexesha, ngelixa i-M2 factor inxulumene ne-laser wavelength.
Ixabiso le-M² factor isondele ngokungenasiphelo kwi-1, oku kuthetha umlinganiselo wedatha yangempela kwidatha efanelekileyo.Xa idatha yangempela isondele kwidatha efanelekileyo, umgangatho we-beam ungcono.
Kwifiber laser enobude obuyi-1070nm, iiparamitha ezifanelekileyo kufuneka zibe:
Xa i-fiber laser BPP okanye i-M2ipharamithaisondele kweli xabiso, umgangatho we-beam ungcono kwaye i-angle yokuhlukana ehambelanayo incinci.
Indlela yokumisela umgangatho we-beam
Ngokuqhelekileyo, sisebenzisa i-analyzer ye-beam ukulinganisa umgangatho we-laser, vumela umhlalutyi ukuba ahambe ngokuhambelana nomzila we-optical, kwaye uqokelele ulwazi lwe-X, Y, kunye no-Z kwiindawo ezininzi ukumisela ubungakanani besinqe, indawo, kunye ne-angle yokuhlukana. , kwaye ubale ubude beRayleigh kunye ne-BPP okanye i-M2.
Ngokuqhelekileyo kusetyenziswa indlela yemela-edge kunye nendlela yokuqhawula.Iimbono zezi zimbini ziyafana, oko kukuthi, sebenzisa imela-edge okanye isiqhekeza ukuskena umqadi, ukulinganisa kunye nemephu yokusasazwa kwebala lokukhanya kwecandelo, emva koko uye phezulu nasezantsi ukulinganisa kunye nemephu yentsimi yokukhanya. imigama eyahlukeneyo.Ekugqibeleni, ukuhanjiswa kwentsimi yokukhanya okuthathu kufunyenwe.
▲ Indlela yemela
▲ Indlela yokuqhawula
Uvavanyo lomgangatho we-beam luhlala luyinkimbinkimbi.Ngokulula, sinokuqikelela uqikelelo ngokwedayamitha yefiber engundoqo kunye nokuvuleka kwamanani (NA).
Umtha wokukhanya, nokuba ungakanani na uluhlu lwe-engile, lunokudluliselwa kuphela ngokuqhelekileyo xa lungena kwifiber ngaphakathi koluhlu lwe-engile yesiganeko esibalulekileyo.Ixabiso lesine sale angle α yinombolo yokuvula i-NA yefiber, oko kukuthi, NA=sinα, ebonisa ukukhanya okufunyenwe yifiber.isakhono.Ngokuqhelekileyo inokuqwalaselwa malunga naloo nto.
Sihlala sithetha ntoni ngeelaser ezikhanyayo?
Ukuqaqamba (Br) Ingcaciso: Uxinaniso lwamandla ngokweyunithi yendawo nganye kunye neyunithi ye-engile eqinileyo.Njengoko besesitshilo ngaphambili, indawo ephambili yefiber laser
, i-engile eqinileyo yentsimi ekude
.
Ngokwale fomyula ingentla, akukho nzima ukubona ukuba okubizwa ngokuba kukukhanya okuphezulu kuthetha ukuba inomgangatho ophezulu we-beam (oko kukuthi, i-BPP encinci okanye i-M.2 ) phantsi kwamandla afanayo.
Njengenkokeli yehlabathi kwiilaser ezikhanyayo,I-GW Laser Tech igxile kuphando kunye nophuhliso lwe-976nm i-fiber lasers ekhanyayo, ekhokelela kwindlela yophuhliso lwe-fiber lasers.

Ukubaluleka kunye neenzuzo zokukhanya okuphezulu
Kwiminyaka yakutshanje, iilaser ezinamandla kakhulu ngokuthe ngcembe ziba yeyona nto iphambili kwintengiso, kwaye iilaser zefiber nazo zisiya kumandla aphezulu.I-laser ye-12KW ibe lulungelelwaniso oluqhelekileyo lwabavelisi belaser abaqhelekileyo.Kunyaka ophelileyo, ukuthengiswa kweGuanghui Laser ye20KW lasers kunyuke kakhulu;okwangoku, iilaser ezingama-40KW ngokuthe ngcembe ziqala ukuthunyelwa ngenqanawa.
Uninzi lwangoku lwangoku lwamandla e-fiber lasers luqulunqwe ziimodyuli ezininzi, oko kukuthi, ukuphuma kokukhanya ngeemodyuli ezininzi zelaser kudityaniswa kwifiber enye yokuphuma.Xa kuthelekiswa nemveliso yefiber core yemodyuli eyodwa ye-laser, iimodyuli ezininzi I-fiber output edibeneyo ye-fiber core diameter inkulu kwaye umgangatho we-beam uphantsi ngokuhambelanayo.
Ukuba umgangatho we-beam ungahoywa, kungakhathaliseki ukuba uphezulu kangakanani amandla, unokuqondwa ngokusebenzisa i-multi-module beam yokudibanisa iskimu.Nangona kunjalo, ngenkqubela phambili yetekhnoloji kunye nokuphuculwa kwemizi-mveliso, ishishini lokuvelisa liya kuhamba ngokuthe ngcembe liye kwinqanaba eliphezulu, eliya kuthi ngokuqinisekileyo libeke phambili iimfuno eziphezulu kunye neziphezulu zeelaser, kungekuphela nje ukwanelisa ukonyuka kwamandla, kodwa kunye nokunikela ingqalelo ngakumbi kuphuculo lokukhanya. .Ezo lasers zamandla aphezulu zonyusa amandla kuphela ngaphandle kokuhoya ukuqaqamba ziya kupheliswa ngokukhawuleza yintengiso.
Ukusukela ekusekweni kwayo, iGW Laser Techuzibophelele kuphando kunye nophuhliso lweelaser ezikhanyayo, kwaye ziya kwandisa amandla kunye nokwandisa ukukhanya ngokulinganayo.Ngokulungiswa kwetekhnoloji yemodyuli ye-laser enye, i-fiber fusion splicing, kunye nezikimu zokudibanisa umqadi, ukukhanya kwelaser kuye kwaphuculwa ngakumbi.Phantsi kweemeko zamandla afanayo, emva kokudibana kunye nokugxininisa yinkqubo yamehlo efanayo, indawo ekugxilwe kuyo incinci kwaye ubuninzi bamandla buphezulu.Oku kubonakaliswa ngokuthe ngqo kwi-laser processing applications: phantsi kwamandla afanayo, isantya sokucubungula sikhawuleza;phantsi kwesantya esifanayo sokucubungula, amandla afunekayo amancinci.
Thatha i-GW Laser's YLPM series 20KW laser cutting njengomzekelo.Xa kuthelekiswa namanye ama-lasers kumandla afanayo, isantya sokusika sikhawuleza, kwaye le nzuzo ibonakala ngokukodwa ekusikeni izinto eziphezulu ezibonisayo.
Iilaser ezikhanyayo ziyindlela ebalulekileyo yophuhliso loshishino lwelaser.Imarike yangoku ye-laser enamandla amakhulu ibonise i-homogeneity ecacileyo, kwaye abavelisi abakhulu be-laser baqhubela phambili kwicala lamandla aphezulu.
GWILaserayikhathaleli nje ngokunyuka kwamandla e-laser, kodwa inika ingqwalasela engakumbi ekuphuculweni kokukhanya kwelaser.Kwixesha elizayo, siya kuqhubeka siphonononga kwicala lokukhanya okuphezulu, ukuze i-laser ibe nomgangatho ongcono we-beam kunye nokusebenza kokusebenza, kwaye inceda abathengi ukuphucula ukusebenza kakuhle.
