I-MAVEN okwangoku ineenguqulelo ezininzi zoomatshini bokucoca i-MOPA fiber laser abanamandla aphezulu abanokwanelisa iimfuno zokucubungula zezicelo ezahlukeneyo kwiinkalo ezahlukeneyo.
Ukuguquguquka kwamandla apheleleyo eeyure ezingama-24 kungaphantsi kwe-<3%
Umgangatho we-beam uyalawuleka
Umqadi weGaussian wemowudi enye Umqadi othe tyaba ophezulu weendlela ezininzi
Itekhnoloji yokudibanisa isignali yokuphela kwepompo, ukusasazwa kwamanqanaba amandla acocekileyo nafanelekileyo, inkqubo yokudibanisa imveliso eyahlukileyo, kunye ne-collimated isolator enamandla aphezulu yemowudi enye enekristale ecacileyo yobushushu, ngelixa amandla okukhupha efikelela kwi-1000W, inokuqinisekisa umgangatho ogqwesileyo weBeam.
Kwicandelo lokucubungula i-fiber laser, ingakumbi ukucutshungulwa kwei-laser yefayibha ye-MOPA enamandla aphezulu, ngenxa yamandla ayo aphezulu, amandla amakhulu okubetha kwentliziyo kunye nokuphindaphinda okuphezulu, ukukhethwa kwezincedisi kubaluleke kakhulu. Izincedisi eziphambili ezichaphazela isiphumo sokucubungula i-laser yokubetha kwentliziyo enamandla aphezulu ziquka i-Scanning galvanometer, i-focused field mirror kunye ne-reflector.
Ungayikhetha njani i-galvanometer yokuskena?
Injongo yetekhnoloji yokuskena i-galvanometer kukugqiba imisebenzi yokuskena ekhawulezayo nechanekileyo. Kukho izinto ezimbini eziphambili zokumisela. Enye yinkqubo yokulawula enokufikelela kwisantya esiphezulu kunye nokuchaneka okuphezulu, kwaye enye yi-galvanometer enesantya esiphezulu sokuphendula. Ulwakhiwo lwe-galvanometer luquka ikakhulu amacandelo amathathu: i-reflector, i-motor kunye ne-drive card, phakathi kwazo ilensi ibalulekile kuzinzo lokucubungula.
Izinto zelensi zeGalvanometer kunye nezalathisi ezinefuthe
Inkqubo yolawulo lobushushu yeukuskena i-galvanometerKwakhona yinto ebalulekileyo ekuqinisekiseni uzinzo lwenkqubo yexesha elide. Umahluko kubushushu uya kubangela ukuba i-galvanometer ikhukulise kwaye inciphise ukuchaneka kokubekwa kwayo. Amaxabiso aqhelekileyo ngala alandelayo. Ngokuphola kwamanzi, ukuzinza kwenkqubo yexesha elide kunokuphuculwa ngama-30%.
Ixabiso eliqhelekileyo lokushukuma kobushushu be-galvanometer
Isixhobo sokupholisa amanzi sinokususa ubushushu ngempumelelo kwaye siqinisekise ukusebenza okuzinzileyo kwexesha elide kwe-galvanometer. Iindlela eziphambili zobugcisa kukufumana intsimi yamanzi okupholisa eguquguqukayo ephantsi ngoyilo oluphuculweyo lomjelo wamanzi okupholisa, kunye nokuyila isakhiwo sesixhobo sokutshintsha ubushushu sangaphandle esisebenzayo.
Kwinkqubo yelaser ye-MOPA pulse enamandla aphezulu ekwi-kilowatt, sicebisa kakhulu ukusetyenziswa kweelensi ze-quartz ezikumgangatho ophezulu kunye neenkqubo ze-galvanometer ezineenkqubo zokupholisa amanzi.
Ungayikhetha njani ilensi yentsimi yokugxila?
Ilensi yasendle igxila umqadi welaser odibeneyo kwindawo ethile, yonyusa uxinano lwamandla omqadi welaser, kwaye isebenzisa amandla aphezulu elaser ukwenza ukucubungula izinto ezahlukeneyo ezifana nokusika, ukumakisha, ukuwelda, ukucoca kunye nonyango lomphezulu.
Izinto eziphambili ezichaphazela umgangatho wokucubungula kunye nefuthe lelensi yentsimi zizinto ezikwilensi yentsimi kunye nokuphakama kweringi ye-adapter. Izinto eziphambili zelensi yentsimi yiglasi kunye ne-quartz. Umahluko phakathi kwezi zimbini ukwimpembelelo yelensi ye-thermal kumandla aphezulu. Emva kokuba ilensi yentsimi egxile kugxininiso isoloko ikhanyiswe yi-laser beam ixesha elide, iya kuvelisa ukuguquguquka kobushushu ngenxa yokunyuka kobushushu, okuya kubangela i-transmission optics. Isalathisi sokuqaqamba kwento kunye nolwalathiso lokubonakalisa lwento ekhanyayo ye-optical iyatshintsha, kwaye isiphumo selensi ye-thermal siya kuchaphazela indlela yelensi kunye nendawo yokugxila emva kokugxila, okuya kuchaphazela kakhulu isiphumo sokucubungula. I-Quartz inomlinganiselo wokwandiswa kobushushu ophantsi kunye nokudluliselwa okuphezulu, okwenza kube lukhetho olungcono lwezinto ezikwilensi yentsimi enamandla aphezulu. Ukuba kuyimfuneko, kufuneka kongezwe imodyuli yokupholisa amanzi.
Iringi yeadaptha yokufanisa ilensi yasendle ne-galvanometer nayo yinto ebalulekileyo echaphazela izixhobo kunye nokucubungula. Ukuphakama okufanelekileyo kweringi yeadaptha kunokuthintela indawo yokubuyela kwelensi yasendle kwaye kuqinisekise ifomathi yokucubungula. Ukuba iphezulu kakhulu okanye iphantsi kakhulu, iya kubangela iingxaki ezifanayo.
Kwiinkqubo ze-laser ze-MOPA pulse ezisebenzisa amandla aphezulu ze-kilowatt, sicebisa kakhulu ukusetyenziswa kwezibuko ze-quartz ezikumgangatho ophezulu ezineemodyuli zokupholisa amanzi kunye neringi ye-adapter yesipili yentsimi ebekelwe bucala enokuphakama okufanelekileyo.
Ungazifanisa njani iilensi ezibonisa ukukhanya?
Umsebenzi ophambili weelensi ezibonisa ukukhanya kwisakhiwo sendlela yokukhanya kukutshintsha indlela yendlela yokukhanya. Ukukhetha iilensi ezibonisa ukukhanya ezisemgangathweni kunye neendlela zokufakela ezisemgangathweni kunokudlala indima enkulu kwezinye izicelo ezikhethekileyo, kodwa iilensi ezikumgangatho ophantsi kunye neendlela zokufakela ezingenangqondo nazo ziya kubangela umbuzo omtsha. Iimpawu zezinto ezibonakalayo zelensi zimiselwa bubude be-wavelength kunye namandla e-laser. I-substrate ngokubanzi yenziwe nge-quartz edibeneyo okanye i-crystalline silicon. Ifilimu ebonakalisa ukukhanya kwe-laser ngokubanzi yenziwe ngefilimu yesilivere okanye ifilimu ye-dielectric ecacileyo, enokukhanya okuphezulu, izinga eliphantsi lokufunxa kunye nokumelana ne-laser. Iimpawu zomda ophezulu womonakalo.
Isixhobo sokubonisa ukukhanya esifanelekileyo asiyi kuchaphazela umgangatho wokugxila, kodwa xa sisetyenziswa ngokwenene, i-reflection plane inokukhubazeka ngenxa yezinto ezibangela uxinzelelo ezifana nokuqina kwezikrufu, njengesipili esisilinda. Ukuphazamiseka kuchaphazela kakhulu umgangatho wendawo yokugxila, okubangela i-astigmatism ephantsi kunye nezinye i-astigmatism ezisezantsi. Ukuphazamiseka kuthintela indawo egxile ekufikeleleni kumda wokuphazamiseka, okuchaphazela umgangatho wokucubungula kunye nesiphumo.
Kwiinkqubo ze-laser ze-MOPA pulse ezinamandla aphezulu ezikwi-kilowatt, sicebisa kakhulu ukusetyenziswa kwee-reflectors ze-quartz ezikumgangatho ophezulu kunye neendlela ezifanelekileyo zokufakela ukuqinisekisa ukuba iilensi zinamandla ngaphandle kokuguquka.
