Ku-laser yamandla kuvamise ukuba wugongolo lwe-Gaussian, okungukuthi, ukushuba kwe-beam emkhathini kuveza ukusatshalaliswa kwe-Gaussian, uthango olunjalo lunomfutho ophakeme kakhulu omaphakathi, futhi luyehla kancane kancane luhambisana nekhonta ye-Gaussian ngaphandle.
Kuzicelo ezisebenzayo, akuzona kuphela imishayo ye-Gaussian evame ukudingeka, kodwa futhi nemishayo ye-laser yezidingo ezithile zohlelo lokusebenza.Isibonelo, ekusabalaliseni amandla, kukhona ukusatshalaliswa kwendandatho;Kumumo we-beam, kunamajamo anjengesikwele, ayindilinga, njll.
Mayelana nokusabalalisa, kukhona ukusatshalaliswa kwendandatho
Ukusatshalaliswa kwamandla kwe-Gaussian beam akufani uma kuqhathaniswa, futhi amandla amaphakathi aphezulu kakhulu, okuzokwenza izinga lokushisa lasendaweni libe phezulu kakhulu futhi kuthinte ukusebenzisana phakathi kwelaser nento;Amandla amaphiko amabili aphansi kakhulu, ehlisa izinga lokusebenzisa.Ngakho-ke, kwezinye izimo, kuyadingeka ukwakha i-Gaussian beam ibe yi-flat-top beam enokusabalalisa kwamandla ngisho ukuze kuthuthukiswe umphumela wokucubungula i-laser.
Izibalo ezilandelayo zibonisa izici zephrofayili ye-laser ye-Gaussian kanye nephrofayela ye-laser ephezulu eyisicaba:
Izingxenye ezinomfutho ophansi kuzo zombili izinhlangothi zendawo etholakalayo emaphakathi yogodo zibizwa ngokuthi “amaphiko amabili” ukuqina kwawo kungaphansi komngcele ovuthayo odingekayo ekusetshenzisweni kokucutshungulwa kwe-laser, futhi amandla ala maphiko amabili avame ukumoshwa, okuholela ekubonakaleni okukhulu. ukunciphisa ukusetshenziswa kwamandla;Ngesikhathi esifanayo, amandla amaphiko amabili azolimaza indawo ezungezile ngaphandle kwendawo okuhlosiwe, ngaleyo ndlela andise indawo ethintekile ukushisa.Ngakolunye uhlangothi, izingxenye eziphakeme kakhulu ngaphezu komngcele ovuthayo zibizwa ngokuthi "amandla angaphezu kwamandla", futhi lawa mandla angaphezu kwamandla anamandla okulimaza i-substrate;Ngaphezu kwalokho, amandla engxenyeni emaphakathi agxile kakhulu, futhi kulula ukulimaza i-optics.
Imishayo ye-laser eyisicaba isebenzisa amandla kahle kakhulu kunemishayo ye-laser ye-Gaussian.Kuphrofayela yebhimu ye-Gaussian, amandla engeziwe phakathi nendawo ngaphezu komkhawulo wokuqina adingwa uhlelo lokusebenza namandla angaphansi kwemfuneko yomkhawulo kuzo zombili izimpiko ayamoshwa.Awekho amaphiko kuphrofayela ye-flat-top beam, kodwa kukhona ukushintshwa konqenqema olukhuphukayo, ngakho-ke ukusetshenziswa kwamandla kusebenza kahle kakhulu futhi umonakalo endaweni ezungezile uyancipha.
Njengoba kungabonwa emfanekisweni ongenhla, amandla e-flat-top beam aqukethwe ngokucace kakhulu endaweni enikeziwe kune-Gaussian beam.Ukushisela noma ukusika nge-flat-topped beam kuyoba nembe kakhulu futhi kuncane ukulimala endaweni ezungezile.
Uma usikwa nge-flat-top beam, ukusikeka okuhlanzekile kanye nemiphetho ebukhali kungakhiqizwa.
Lapho i-welding nge-flat-top beam, izikhala ku-weld zizoba bushelelezi kunezinsimbi ze-gaussian.
Yibuphi ububi bemishayo eyisicaba?
Ngokungafani nemishayo ye-Gaussian, ukwakheka kokuqina kuyashintsha njengoba kusakazeka endaweni ekhululekile, ngakho-ke akusizi ekusakazeni ibanga elide.Ngesikhathi sokusatshalaliswa kwe-Gaussian beam, noma usayizi we-beam ushintsha, uhlaka lwe-beam kuseyi-Gaussian.
Imvamisa i-laser ikhipha ugongolo lwe-Gaussian, bese kuthi ezinye izingxenye ze-optical ezifanele zisetshenziselwe ukushintsha ukuqina kwayo ukuze kutholwe ugongolo oluyisicaba.
Ubuchwepheshe be-HBF be-Guanghui Laser obuhlukile(I-Flat-top enokukhanya okuphezulu),ngokusebenzisa i-fiber optical okukhipha ukukhanya okuphezulu okuyisicaba okuphezulu, umkhawulo wendawo ubukhali, umkhawulo wamandla aphezulu, ungathuthukisa izinga lokusebenzisa amandla e-laser ngenkathi unciphisa indawo ethintekile ukushisa nomonakalo, uthuthukise ngempumelelo isivinini sokucubungula i-laser nokunemba.
Uma sithatha i-laser engu-5M-12000W ye-Guanghui Laser njengesibonelo, uma kuqhathaniswa namanye ama-lasers akwibhendi yamandla efanayo, izinga lokusebenzisa amandla lingathuthukiswa kakhulu, futhi umfanekiso onembile kakhulu ukuthi isivinini sokusika siyashesha kakhulu.
Lapho usika amapuleti awugqinsi (i-oksijini esika insimbi ye-carbon engu-16mm eboniswe kumfanekiso ongezansi), ukusika kwendawo ephezulu eyisicaba kusetshenziswa ubuchwepheshe be-HBF kubushelelezi futhi umphetho osikiwe ubukhali kunendawo ye-Gaussian.
Iziqongo ze-Gaussian neziyisicaba ziyisici esibalulekile se-laser beam, futhi ngemva kokuqonda umehluko wazo, zingakhethwa ngokunengqondo ngokwalo mehluko ekucutshungulweni kwe-laser okuzayo.
