I-Laser inezici ezine eziyinhloko, okuwukuthi ukukhanya okuphezulu, isiqondiso esihle, i-monochromaticity enhle, nokuhambisana okuphezulu.Lezi zakhiwo zihlobene nomunye nomunye, okwenza i-laser ifanele izimo ezihlukahlukene.
Ukukhanya okuphezulu kwe-laser kuyisici esibalulekile esihlukile emithonjeni yokukhanya evamile, futhi ukwandisa amandla nokukhanya futhi kuyisihloko saphakade sokuthuthukiswa kwama-lasers.Yini ukukhanya okuphezulu, okuvezwa ngolimi lobuchwepheshe ukuthi okusondele ku-1 yinkomba engu-M2 echaza ikhwalithi ye-beam.
Eminyakeni yakamuva, ngokuthuthukiswa kobuchwepheshe, ama-laser fiber asekhaya aphule kancane kancane umkhawulo wamandla, ukusuka ku-12KW kuya ku-20KW.Njengamanje, i-fiber laser ephezulu kakhulu enamandla angu-30KW yethuliwe emakethe, futhi isinyathelo esilandelayo ngu-50KW.Wonke umuntu uyanaka futhi aqhudelane ngokuthi amandla kabani okukhipha i-laser aphezulu, kodwa aziba ukuthi ubani onekhwalithi engcono ye-beam.
Namuhla ake sibheke ukuthi kuyini ukukhanya okuphezulu, kanye nezinzuzo kanye nokubaluleka kokukhanya okuphezulu.
Izici ze-laser beam
Ukukhanya kwe-laser okukhishwa yi-laser kubukeka kanje, kuqala kuhlangana endaweni eseduze, bese kusakazeka endaweni ekude.
phakathi,
Irediyasi okhalo lwe-beam u-w0 iyiradiyasi lapho ugongolo lwe-laser luhlangana khona lube engxenyeni encane kakhulu endaweni eseduze;
I-Rayleigh ubude be-ZR yisimo lapho ukhalo lwe-beam lukhuliswa izikhathi ezingu-√2;
Inkambu ekude ichazwa njengobubanzi obudlula izikhathi ezi-4 zobude be-Rayleigh, futhi inkambu eseduze ichazwa njengobubanzi phakathi kwezikhathi ezi-4 zobude be-Rayleigh;
I-engeli ye-divergence angle θ imele izinga lokuhluka kwe-laser beam endaweni ekude.
Ukulingiswa kwekhwalithi ye-Beam
Ikhwalithi ye-beam iyipharamitha ewumgogodla yokubonisa izici ze-laser beam, futhi iyinkomba ebalulekile ye-laser, esetshenziselwa ukukala izinga lokugxila kwe-laser beam esimweni esithile.Izindlela ezivame ukusetshenziswa zokulinganisa ikhwalithi ye-beam yilezi: umkhiqizo wepharamitha ye-beam (BPP) kanye ne-M2isici.
I-BPP (Umkhiqizo wepharamitha ye-Beam): umkhiqizo wepharamitha ye-beam, echazwa njengerediyasi okhalweni lwe-beam (w0) iphindwe nge-engeli yokuhlukana kwenkundla ekude (θ):
M2: Isilinganiso somkhiqizo wepharamitha yepharamitha kumkhiqizo wepharamitha yepharamitha ye-Gaussian eyisisekelo, engaguqulelwa ku-BPP:
Kusukela kufomula engenhla, singathola kalula ukuthi: I-BPP ayihlangene nobude begagasi, kuyilapho isici se-M2 sihlobene nobude begagasi be-laser.
Inani le-M² factor lisondele kakhulu ku-1, okusho isilinganiso sedatha yangempela kudatha efanelekile.Uma idatha yangempela iseduze nedatha efanelekile, ikhwalithi ye-beam iba ngcono.
Ukuze uthole i-fiber laser enobude obungu-1070nm, imingcele efanelekile kufanele ibe:
Lapho i-fiber laser BPP noma i-M2ipharamithaiseduze naleli nani, ikhwalithi ye-beam ingcono futhi i-engeli yokuhlukana ehambisanayo incane.
Indlela yokunquma ikhwalithi ye-beam
Ngokuvamile, sisebenzisa i-analyzer ye-beam ukukala ikhwalithi ye-laser, sivumele isihlaziyi sihambe ngokuhlobene nendlela yokubona, futhi siqoqe ulwazi lwe-X, Y, no-Z ezindaweni eziningi ukuze sinqume usayizi wokhalo lwe-beam, indawo, kanye ne-engeli yokuhlukana. , futhi ubale ubude be-Rayleigh ne-BPP noma i-M2.
Okuvame ukusetshenziswa indlela yonqenqema lommese kanye nendlela yokusika.Imibono yalokhu okubili iyafana, okungukuthi, sebenzisa unqenqema lommese noma ukusika ukuze uskene i-beam, ulinganise futhi wenze imephu ukusatshalaliswa kwenkambu yokukhanya kwesigaba, bese ukhuphuka uye phansi ukuze ulinganise futhi wenze imephu inkambu yokukhanya amabanga ahlukene.Ekugcineni, ukusabalalisa kwenkambu yokukhanya okunezinhlangothi ezintathu kuyatholakala.
▲ Indlela yonqenqema lommese
▲ Indlela yokuhlukanisa
Ukuhlolwa kwekhwalithi ye-beam kuvame ukuba nzima kakhulu.Kalula nje, singakwazi ukulinganisa isilinganiso ngokuya ngobubanzi be-fiber core kanye nendawo yokuvula izinombolo (NA).
I-beam yokukhanya, kungakhathaliseki ukuthi ububanzi be-engeli bukhulu kangakanani, ingadluliselwa ngokujwayelekile kuphela uma ingena ku-fiber ngaphakathi kwebanga le-engeli lesigameko esibalulekile.Inani lesine lale engeli engu-α imbobo yenombolo NA yefayibha, okungukuthi, NA=sinα, ebonisa ukukhanya okutholwe umcu.ikhono.Ngokuvamile kungabhekwa cishe lokho.
Sivame ukusho ukuthini ngamalaser anokukhanya okuphezulu?
Ukukhanya (Br) Incazelo: Ukuminyana kwamandla endaweni yeyunithi ngayinye kanye neyunithi ye-engeli eqinile.Njengoba sishilo ngaphambili, indawo eyinhloko ye-fiber laser
, i-engeli eqinile yenkundla ekude
.
Ngokusho kwefomula engenhla, akunzima ukubona ukuthi lokho okubizwa ngokuthi ukukhanya okuphezulu kusho ukuthi inekhwalithi ephezulu ye-beam (okungukuthi, i-BPP encane noma i-M.2 ) ngaphansi kwamandla afanayo.
Njengomholi womhlaba wonke kuma-laser akhanya kakhulu,I-GW Laser Tech igxile ocwaningweni nasekuthuthukisweni kwama-laser wefiber agqama kakhulu angu-976nm, okuholela ekuthuthukisweni kwama-laser wefiber.
I-Guanghui Laserakayedwa-imodi 10μmnciphisa i-fiber okukhipha i-laser, i-M2I-laser yefayibha engu-<1.1, kanye ne-50kw 100μm inokuminyana kwamandla eduze nomkhawulo ongokwenyama.
Ububanzi obungu-100μm obuyinhloko bemodi eyodwa engu-4kW laser M2<1.3, multi-mode 12kW laser BPP<4.

Ukubaluleka kanye nezinzuzo zokukhanya okuphezulu
Eminyakeni yamuva nje, ama-laser anamandla amakhulu kancane kancane aba amandla amakhulu emakethe, futhi ama-fiber lasers nawo aqhubekela phambili emandleni aphezulu.Ama-laser angu-12KW asephenduke ukumiswa okujwayelekile kwabakhiqizi be-laser abajwayelekile.Ngonyaka odlule, ukuthengiswa kwe-Guanghui Laser kwama-laser angu-20KW kunyuke kakhulu;okwamanje, ama-lasers angu-40KW kancane kancane aqala ukuthunyelwa.
Iningi lamanje lama-fiber lasers anamandla aphezulu akhiwe amamojula amaningi, okungukuthi, ukuphuma kokukhanya ngamamojula e-laser amaningi kuhlanganiswe kube i-optical fiber eyodwa ukuze ikhiphe.Uma kuqhathaniswa ne-fiber core ephumayo yemojula eyodwa ye-laser, amamojula amaningi I-diameter ye-fiber core ehlanganisiwe inkulu futhi ikhwalithi ye-beam iphansi ngokuhambisanayo.
Uma ikhwalithi ye-beam inakwa, kungakhathaliseki ukuthi amandla aphakeme kangakanani, ingenziwa ngohlelo lokuhlanganisa i-multi-module ye-beam.Kodwa-ke, ngenqubekelaphambili yezobuchwepheshe kanye nokuthuthukiswa kwezimboni, imboni yezokukhiqiza izohamba kancane kancane iye ekupheleni okuphezulu, okuzobeka phambili izidingo eziphakeme neziphakeme zama-lasers, hhayi nje ukwanelisa ukwanda kwamandla, kodwa futhi ukunaka kakhulu ukuthuthukiswa kokukhanya. .Lawo ma-laser anamandla amakhulu akhulisa amandla kuphela ngaphandle kokunaka ukukhanya azoqedwa yimakethe maduze.
Kusukela yasungulwa, i-GW Laser Techuzibophezele ocwaningweni nasekuthuthukisweni kwama-laser anokukhanya okuphezulu, futhi azokhulisa amandla futhi akhulise ukukhanya ngokulinganayo.Ngokusetshenziswa kahle kobuchwepheshe bemojula ye-laser eyodwa, ukuhlanganisa i-fiber fusion, kanye nezinhlelo zokuhlanganisa izigxobo, ukukhanya kwe-laser kuye kwathuthukiswa nakakhulu.Ngaphansi kwezimo ezifanayo zamandla, ngemva kokungqubuzana nokugxila ngesistimu yokubona efanayo, indawo lapho kugxilwe khona incane futhi ukuminyana kwamandla kuphezulu.Lokhu kubonakaliswa ngokuqondile ekusetshenzisweni kokucubungula kwe-laser: ngaphansi kwamandla afanayo, isivinini sokucubungula siyashesha;ngaphansi kwejubane elifanayo lokucubungula, amandla adingekayo mancane.
Thatha uchungechunge lwe-GW Laser's YLPM 20KW njengesibonelo.Uma kuqhathaniswa namanye ama-lasers ngamandla afanayo, ijubane lokusika liyashesha, futhi le nzuzo ibonakala ikakhulukazi ekusikeni izinto ezibonisa ukukhanya okuphezulu.
Ama-laser akhanya kakhulu ayisiqondiso esibalulekile sokuthuthukiswa kwemboni ye-laser.Imakethe yamanje ye-laser enamandla amakhulu ibonise i-homogeneity esobala, futhi abakhiqizi abakhulu be-laser bathuthukela ohlangothini lwamandla abekwe ngaphezulu.
GWI-Laserakakhathaleli nje kuphela ngokwanda kwamandla e-laser, kodwa futhi unaka kakhulu ekuthuthukisweni kokukhanya kwe-laser.Ngokuzayo, sizoqhubeka nokuhlola esiqondisweni sokukhanya okuphezulu, ukuze i-laser ibe nekhwalithi engcono ye-beam nokusebenza kokucubungula, futhi isize amakhasimende athuthukise ukusebenza kahle kokucubungula.
