Njengendlela yokucoca esebenzayo nengenabungozi kokusingqongileyo,iteknoloji yokucoca laserngokuthe ngcembe ithatha indawo yokucoca imichiza yemveli kunye neendlela zokucoca ngoomatshini. Ngeemfuno zelizwe ezingqongqo zokukhuselwa kokusingqongileyo kunye nokusukela ngokuqhubekayo ukucoca umgangatho kunye nokusebenza kakuhle kwintsimi yokwenziwa kwemizi-mveliso, imfuno yemarike yeteknoloji yokucoca i-laser ikhula ngokukhawuleza. Njengelizwe elikhulu lemveliso, i-China inesiseko esikhulu semizi-mveliso, esibonelela ngesithuba esibanzi sokusetyenziswa ngokubanzi kwetekhnoloji yokucoca i-laser. Kwi-aerospace, ukuhamba ngololiwe, ukuveliswa kweemoto, ukuveliswa kokubumba kunye namanye amashishini, iteknoloji yokucoca i-laser isetyenziswe ngokubanzi kwaye ngokuthe ngcembe yanda kwamanye amashishini.
Itekhnoloji yokucoca indawo yokusebenza isetyenziswa kakhulu kwiinkalo ezininzi. Iindlela zokucoca eziqhelekileyo zivame ukucocwa koqhagamshelwano, okwenza amandla omatshini phezu kwendawo yokucocwa, eyonakalisa ubuso bento okanye i-medium yokucoca ibambelela kumphezulu wento ekufuneka icocwe kwaye ayikwazi ukususwa. , ebangela ungcoliseko lwesibini. Kule mihla, ilizwe likhuthaza uphuhliso lwamashishini asakhasayo aluhlaza kunye nokusingqongileyo, kwaye ukucocwa kwelaser lolona khetho lungcono. Ubume obunganyangekiyo kunye nobokungaqhagamshelwanga kokucoca nge-laser kusombulula ezi ngxaki. Izixhobo zokucoca i-Laser zifanelekile ukucoca izinto zezinto ezahlukeneyo kwaye zibhekwa njengeyona ndlela inokuthenjwa kwaye isebenzayo yokucoca.
Ukucocwa kweLaserumgaqo
Ukucocwa kweLaser kukukhupha i-laser-high-energy-density beam ye-laser kwinxalenye yento ekufuneka ihlanjululwe, ukwenzela ukuba i-laser ifakwe ngumaleko wokungcola kunye ne-substrate. Ngokusebenzisa iinkqubo ezifana nokuhluthwa kokukhanya kunye ne-vaporization, ukunamathela phakathi kwezinto ezingcolileyo kunye ne-substrate kunqotshwa, ukwenzela ukuba i-I-contaminants ishiye ubuso bento ukufezekisa injongo yokucoca ngaphandle kokulimaza into ngokwayo.
Umzobo 1: Umzobo ocwangcisiweyo wokucoca i-laser.
Kwintsimi yokucoca i-laser, ii-laser ze-fiber ziye zaba ngumnqobi phakathi kwemithombo yokukhanya yokucoca i-laser ngenxa ye-ultra-high photoelectric yokuguqulwa kwe-photoelectric ukusebenza kakuhle, umgangatho obalaseleyo we-beam, ukusebenza okuzinzileyo kunye nophuhliso oluzinzileyo. Iilaser zeFiber zimelwe zintlobo ezimbini: iilaser zefiber pulsed kunye nefiber lasers eziqhubekayo, ezihlala kwimakethi ekhokela izikhundla ekusetyenzweni kwemathiriyeli enkulu kunye nokuchaneka kwezinto ngokulandelelanayo.
Umzobo 2: Ukwakhiwa kwe-fiber fiber laser.
I-Pulsed Fiber Laser vs. IFayibha yeLaser eqhubekayo yokuCoca ukuFaniswa kwesicelo
Kwizicelo zokucoca ngelaser ezivelayo, abantu abaninzi banokubhideka kancinci xa bejongene ne-pulse lasers kunye nelases eziqhubekayo kwimarike: Ngaba kufuneka bakhethe iilaser ze-pulse fibre okanye i-fiber lasers eqhubekayo? Apha ngezantsi, zimbini iintlobo ezahlukeneyo zeelaser ezisetyenziselwa ukuqhuba iimvavanyo zokususa ipeyinti kumphezulu wezinto ezimbini, kunye neeparamitha zokucoca ngelaser kunye neziphumo zokucoca eziphuculweyo zisetyenziselwa ukuthelekisa.
Ngokujongwa nge-microscopic, i-sheet metal iye yanyibilika emva kokucutshungulwa ngamandla aphezulu e-fiber laser. Emva kokuba insimbi icutshungulwe yi-MOPA pulse fiber laser, izinto ezisisiseko zonakaliswe kancinci kwaye ukuthungwa kwezinto ezisisiseko kugcinwa; emva kokuba intsimbi icutshungulwe yi-fiber laser eqhubekayo, umonakalo omkhulu kunye nezinto ezityhidiweyo ziveliswa.

Ukusuka kolu thelekiso lungasentla, kunokubonwa ukuba iilaser zefiber eziqhubekayo zinokubangela ngokulula ukubola kunye nokuguqulwa kwe-substrate ngenxa yegalelo labo elikhulu lobushushu. Ukuba iimfuno zomonakalo we-substrate aziphezulu kwaye ubukhulu bezinto eziza kuhlanjululwa zincinci, olu hlobo lwe-laser lunokusetyenziswa njengomthombo wokukhanya. I-laser ye-fiber ye-pulsed ixhomekeke kumandla aphezulu aphezulu kunye nokuphindaphinda okuphindaphindiweyo kwee-pulses ukuze isebenze kwizinto eziphathekayo, kwaye ikhuphe ngokukhawuleza kwaye idibanise izinto zokucoca ukuze zixobule; ineempembelelo ezincinci ze-thermal, ukuhambelana okuphezulu, kunye nokuchaneka okuphezulu, kwaye inokufikelela kwimisebenzi eyahlukeneyo. Ukutshabalalisa iimpawu ze-substrate.
Ukususela kwesi sigqibo, ebusweni bokuchaneka okuphezulu, kuyimfuneko ukulawula ngokuthe ngqo ukunyuka kweqondo lokushisa kwe-substrate, kwaye kwiimeko zesicelo ezifuna ukuba i-substrate ingabi yinto eyonakalisayo, njenge-aluminium epeyintiweyo kunye nentsimbi yokubumba, kuyacetyiswa ukuba khetha i-pulse fiber laser; kwezinye izinto ezinkulu ze-aluminium alloy alloy, imibhobho ejikelezileyo, njl njl
In ukucoca ngelaser, iimeko zezinto eziphathekayo kufuneka ziqwalaselwe ngokubanzi ukuqinisekisa ukuba iimfuno zokucoca ziyafezekiswa ngelixa kuncitshiswa umonakalo kwi-substrate. Ngokweemeko zokwenyani zokusebenza, kubalulekile ukukhetha umthombo ofanelekileyo wokukhanya kwelaser.
Ukuba ukucocwa kwe-laser kufuna ukungena kwi-application-scale-scale, ayinakuhlukaniswa kwi-innovation ye-teknoloji entsha kunye neenkqubo ezintsha. I-Maven iya kuqhubeka nokubambelela ekubekweni kwe-laser +, ilawule isantya sophuhliso ngokuthe ngcembe, izame ukwenza nzulu itekhnoloji yomthombo wokukhanya we-laser, kwaye igxininise ekusombululeni izinto eziphambili zelaser kunye nemiba ephambili yamacandelo ibonelela ngomthombo wamandla kwimveliso ephezulu. .
