Inkcazelo yoLwakhiwo lwe-MOPA (Master Oscillator Power Amplifier)
Kwicandelo lobuchwepheshe be-laser, isakhiwo se-Master Oscillator Power Amplifier (MOPA) simi njengesibonakaliso sobuchule, esiyilelwe ukukhupha iziphumo ze-laser ezikumgangatho ophezulu kunye namandla. Le nkqubo intsonkothileyo yenziwe ngamacandelo amabini abalulekileyo: i-Master Oscillator kunye ne-Power Amplifier, nganye idlala indima eyahlukileyo nebalulekileyo.
I-Oscillator eNkulu:
Intliziyo yenkqubo ye-MOPA ikwi-Master Oscillator, into enoxanduva lokuvelisa i-laser enobude obuthile, ukuhambelana, kunye nomgangatho ophezulu we-beam. Nangona imveliso ye-Master Oscillator idla ngokuba namandla aphantsi, ukuzinza kwayo kunye nokuchaneka kwayo kudala isiseko sendlela esebenza ngayo yonke inkqubo.
Isandisi-mandla:
Umsebenzi ophambili wePower Amplifier kukwandisa i-laser eveliswa yiMaster Oscillator. Ngothotho lweenkqubo zokukhulisa, iphucula kakhulu amandla e-laser ngelixa izama ukugcina ukuthembeka kweempawu zomqadi wokuqala, njengobude be-wavelength kunye nokuhambelana.
Le nkqubo inamacandelo amabini ngokuyintloko: ngasekhohlo, kukho umthombo we-seed laser onomgangatho ophezulu wokukhupha, kwaye ngasekunene, kukho isakhiwo se-optical fiber amplifier yesigaba sokuqala okanye esinezigaba ezininzi. Ezi nxalenye zimbini xa zidibene zenza umthombo we-optical we-master oscillator power amplifier (MOPA).
Ukwandiswa kweZiteji ezininzi kwiMOPA
Ukuze kuphuculwe amandla elaser kwaye kuphuculwe umgangatho wemitha, iinkqubo zeMOPA zinokubandakanya izigaba ezininzi zokukhulisa. Isigaba ngasinye senza imisebenzi eyahlukeneyo yokukhulisa, kunye nokufezekisa ukudluliselwa kwamandla ngokufanelekileyo kunye nokusebenza kakuhle kwelaser.
I-Pre-amplifier:
Kwinkqubo yokukhulisa amandla enezigaba ezininzi, i-Pre-amplifier idlala indima ebalulekileyo. Inika ukukhulisa amandla okuqala kwimveliso ye-Master Oscillator, ilungiselela i-laser kwizigaba ezilandelayo, zokukhulisa amandla aphezulu.
Isandisi-lizwi esiPhakathi:
Eli nqanaba linyusa amandla elaser ngakumbi. Kwiinkqubo zeMOPA ezintsonkothileyo, kunokubakho amanqanaba amaninzi ee-Intermediate Amplifiers, ngalinye linyusa amandla ngelixa liqinisekisa umgangatho we-laser beam.
Isandisi-lizwi Sokugqibela:
Njengesigaba sokugqibela sokukhulisa, iFinal Amplifier iphakamisa amandla elaser ukuya kwinqanaba elifunekayo. Kufuneka ingqwalasela ekhethekileyo kweli nqanaba ukulawula umgangatho wemitha kunye nokuthintela ukuvela kweziphumo ezingezizo ezomgca.
Izicelo kunye neenzuzo zesakhiwo se-MOPA
Isakhiwo se-MOPA, esinokukwazi ukubonelela ngemveliso enamandla aphezulu ngelixa sigcina iimpawu zelaser ezifana nokuchaneka kwe-wavelength, umgangatho we-beam, kunye nokuma kwe-pulse, sifumana izicelo kwiinkalo ezahlukeneyo. Ezi ziquka ukucutshungulwa kwezinto ngokuchanekileyo, uphando lwesayensi, iteknoloji yezonyango, kunye nonxibelelwano lwe-fiber optic, ukukhankanya ezimbalwa. Ukusetyenziswa kwetekhnoloji yokukhulisa i-multistage kuvumela iinkqubo ze-MOPA ukuba zinike ii-laser ezinamandla aphezulu ngokuguquguquka okumangalisayo kunye nokusebenza okugqwesileyo.
I-MOPAI-Fiber LaserUkusuka kwiLumispot Tech
Kwi-LSP pulse fiber laser series, iI-laser yefayibha ye-pulse ye-1064nm nanosecondisebenzisa isakhiwo se-MOPA (Master Oscillator Power Amplifier) esilungiselelwe kakuhle esinetekhnoloji yokukhulisa amandla enamanqanaba amaninzi kunye noyilo lwemodyuli. Inengxolo ephantsi, umgangatho ogqwesileyo wemitha, amandla aphezulu, uhlengahlengiso oluguquguqukayo lweeparameter, kunye nokulula kokudibanisa. Le mveliso isebenzisa itekhnoloji yokubuyisela amandla elungiselelwe kakuhle, ithintela ngempumelelo ukubola kwamandla okukhawulezileyo kwiindawo ezinobushushu obuphezulu kunye nobushushu obuphantsi, okwenza ukuba ifaneleke kakhulu kwizicelo kwiI-TOF (Ixesha lokuHamba ngenqwelo-moya)amasimi okuchonga.
