Njengendlela yokucoca esebenzayo neyobuhlobo nokusingqongileyo,iteknoloji yokucoca nge-laserithatha indawo kancinci kancinci kwindlela yokucoca iikhemikhali zemveli kunye neendlela zokucoca ngoomatshini. Ngenxa yeemfuno zokhuseleko lokusingqongileyo ezingqongqo ngakumbi zelizwe kunye nokuqhubeka nokufuna umgangatho wokucoca kunye nokusebenza kakuhle kwicandelo lokuvelisa izimboni, imfuno yemarike yetekhnoloji yokucoca nge-laser ikhula ngokukhawuleza. Njengelizwe elikhulu lokuvelisa, iTshayina inesiseko esikhulu semizi-mveliso, esibonelela ngendawo ebanzi yokusetyenziswa ngokubanzi kwetekhnoloji yokucoca nge-laser. Kwi-aerospace, ezothutho lukaloliwe, ukuveliswa kweemoto, ukuveliswa kwesikhunta kunye namanye amashishini, itekhnoloji yokucoca nge-laser isetyenziswa kakhulu kwaye iyanda kancinci kancinci iye kwamanye amashishini.
Itekhnoloji yokucoca umphezulu wezinto zokusebenza isetyenziswa kakhulu kwiindawo ezininzi. Iindlela zokucoca zemveli zihlala zicoca ngokuchukumisa, nto leyo enika amandla oomatshini kumphezulu wento eza kucocwa, yonakalisa umphezulu wento okanye isixhobo sokucoca sinamathela kumphezulu wento eza kucocwa kwaye asinakususwa. , nto leyo ebangela ungcoliseko lwesibini. Kule mihla, ilizwe likhuthaza uphuhliso lwamashishini asakhasayo aluhlaza nanobuhlobo nokusingqongileyo, kwaye ukucoca nge-laser lolona khetho lubalaseleyo. Indlela yokucoca nge-laser engangcolisiyo nengangcolisiyo isombulula ezi ngxaki. Izixhobo zokucoca nge-laser zifanelekile ukucoca izinto zezixhobo ezahlukeneyo kwaye zithathwa njengeyona ndlela yokucoca ethembekileyo nesebenzayo.
Ukucoca nge-laserumgaqo
Ukucocwa nge-laser kukukhanyisa umqadi we-laser onamandla aphezulu kwindawo yento eza kucocwa, ukuze i-laser ifunxwe ngumaleko wokungcola kunye ne-substrate. Ngeenkqubo ezinje ngokususa ukukhanya kunye nokufuma, ukunamathelana phakathi kwezinto ezingcolisayo kunye ne-substrate kuyasuswa, ukuze izinto ezingcolisayo ziphume kumphezulu wento ukuze kufezekiswe injongo yokucoca ngaphandle kokonakalisa into ngokwayo.
Umfanekiso 1: Umzobo wesicwangciso sokucocwa nge-laser.
Kwicandelo lokucocwa nge-laser, ii-fiber lasers ziye zaba ziphumelele phakathi kwemithombo yokukhanya yokucoca nge-laser ngenxa yokusebenza kwazo okuphezulu kakhulu kokuguqula i-photoelectric, umgangatho ogqwesileyo we-beam, ukusebenza okuzinzileyo kunye nophuhliso oluzinzileyo. Ii-fiber lasers zimelwe ziintlobo ezimbini: ii-pulsed fiber lasers kunye nee-continuous fiber lasers, ezithatha indawo ephambili kwimarike ekucutshungulweni kwezinto ezinkulu kunye nokulungiswa kwezinto ngokuchanekileyo ngokwahlukeneyo.
Umfanekiso 2: Ukwakhiwa kweleza yefayibha etyhalwayo.
Uthelekiso lwesicelo sokucoca i-Pulsed Fiber Laser vs. Ukucoca i-Fiber Laser okuqhubekayo
Kwizicelo zokucoca nge-laser ezisandula ukwenzeka, abantu abaninzi banokubhideka kancinci xa bejongene ne-pulse lasers kunye ne-continuous lasers ezithengiswayo: Ngaba kufuneka bakhethe i-pulse fiber lasers okanye i-continuous fiber lasers? Ngezantsi, iintlobo ezimbini ezahlukeneyo ze-laser zisetyenziselwa ukwenza uvavanyo lokususa ipeyinti kumphezulu wezinto ezimbini, kwaye iiparameter ezifanelekileyo zokucoca nge-laser kunye neziphumo zokucoca eziphuculweyo zisetyenziselwa ukuthelekisa.
Ngokujonga ngemicroscope, isinyithi sesinyithi siye sanyibilika emva kokuba sicutshungulwe yilaser yefayibha eqhubekayo enamandla aphezulu. Emva kokuba intsimbi icutshungulwe yilaser yefayibha ye-MOPA pulse, izinto ezisisiseko zonakele kancinci kwaye ubume bezinto ezisisiseko bugcinwa; emva kokuba intsimbi icutshungulwe yilaser yefayibha eqhubekayo, umonakalo omkhulu kwaye izinto ezinyibilikisiweyo ziyaveliswa.

Ukusuka kuthelekiso olungentla, kunokubonwa ukuba ii-laser zefayibha eziqhubekayo zinokubangela ngokulula ukutshintsha kombala kunye nokuguquka kwe-substrate ngenxa yokufaka kwazo ubushushu obukhulu. Ukuba iimfuno zomonakalo we-substrate aziphezulu kwaye ubukhulu bezinto eziza kucocwa buncinci, olu hlobo lwe-laser lungasetyenziswa njengomthombo wokukhanya. I-laser yefayibha etyhalwayo ixhomekeke kumandla aphezulu kunye nee-pulses eziphindaphindayo eziphezulu ukuze isebenze kwizinto, kwaye ngoko nangoko ikhupha umphunga kwaye idibanise izixhobo zokucoca ukuze izikhuphe; inemiphumo emincinci yobushushu, ukuhambelana okuphezulu, kunye nokuchaneka okuphezulu, kwaye inokufezekisa imisebenzi eyahlukeneyo. Itshabalalisa iimpawu ze-substrate.
Ukusuka kwesi sigqibo, xa kujongwe ukuchaneka okuphezulu, kuyimfuneko ukulawula ngokungqongqo ukunyuka kobushushu be-substrate, kwaye kwiimeko zokusetyenziswa ezifuna ukuba i-substrate ingabi yonakalisa, njenge-aluminium epeyintiweyo kunye nentsimbi yokubumba, kuyacetyiswa ukuba ukhethe i-laser ye-pulse fiber; kwezinye izinto ezinkulu ze-aluminium alloy ezinamandla aphezulu, iipayipi ezimile okwesangqa, njl. Ngenxa yobukhulu bazo obukhulu kunye nokuchithwa kobushushu ngokukhawuleza, kunye neemfuno eziphantsi kumonakalo we-substrate, ii-laser ze-fiber eziqhubekayo zinokukhethwa.
In ukucoca nge-laser, iimeko zezinto kufuneka ziqwalaselwe ngokupheleleyo ukuqinisekisa ukuba iimfuno zokucoca ziyafezekiswa ngelixa kuncitshiswa umonakalo kwisiseko. Ngokweemeko zokusebenza zangempela, kubalulekile ukukhetha umthombo wokukhanya welaser ofanelekileyo.
Ukuba ukucocwa kwelaser kufuna ukungena kwisicelo esikhulu, akunakuhlukaniswa nokuveliswa kweteknoloji entsha kunye neenkqubo ezintsha. IMaven iya kuqhubeka nokunamathela kwindawo yelaser+, ilawule isantya sophuhliso ngokuthe chu, izame ukugxininisa iteknoloji yomthombo wokukhanya welaser ophambili, kwaye igxile ekusombululeni izixhobo zelaser eziphambili kunye nemiba ephambili yamacandelo ibonelela ngomthombo wamandla kwimveliso ephucukileyo.
