Kuyini ukuhlanza nge-laser
Ngokuveza amandla e-laser agxilile ebusweni bento yokusebenza engcolile, ukuhlanza nge-laser kungasusa ungqimba lokungcola ngokushesha ngaphandle kokulimaza inqubo ye-substrate. Kuyisinqumo esifanele sesizukulwane esisha sobuchwepheshe bokuhlanza bezimboni.
Ubuchwepheshe bokuhlanza nge-laser bubuye baba ubuchwepheshe bokuhlanza obubalulekile embonini, ekwakheni imikhumbi, ezindiza, nakwezinye izinkambu zokukhiqiza ezisezingeni eliphezulu, okuhlanganisa ukususwa kokungcola kwerabha ebusweni besikhunta samathayi, ukususwa kokungcola kwamafutha e-silicon ebusweni befilimu yegolide, kanye nokuhlanza okunembe kakhulu embonini yama-microelectronics.
Izicelo zokuhlanza nge-laser ezijwayelekile
◾ Ukususwa Kopende
◾ Ukususwa Kwamafutha
◾ Ukususwa kwe-Oxide
Ngobuchwepheshe be-laser njengokusika nge-laser, ukuqopha nge-laser, ukuhlanza nge-laser, kanye nokushisela nge-laser, ungase ujwayelene nalokhu kodwa umthombo we-laser ohlobene. Kukhona ifomu lokubhekisela kuwe elimayelana nemithombo ye-laser emine kanye nezinto ezihambisanayo kanye nezinhlelo zokusebenza ezifanele.
Umthombo we-laser one mayelana nokuhlanzwa kwe-laser
Ngenxa yokwehluka kwamapharamitha abalulekile njengobude besikhathi namandla omthombo we-laser ohlukile, izinga lokumuncwa kwezinto ezahlukene kanye namabala, ngakho-ke udinga ukukhetha umthombo we-laser ofanele womshini wakho wokuhlanza i-laser ngokuya ngezidingo ezithile zokususa ukungcola.
▶ Ukuhlanza i-MOPA Pulse Laser
(ukusebenza kuzo zonke izinhlobo zezinto)
I-laser ye-MOPA iwuhlobo olusetshenziswa kakhulu lokuhlanza nge-laser. I-MO imele i-master oscillator. Njengoba uhlelo lwe-laser ye-fiber ye-MOPA lungandiswa ngokuhambisana ngokuqinile nomthombo wesignali yembewu ohlanganiswe nohlelo, izici ezifanele ze-laser njengobude besikhathi obuphakathi, i-pulse waveform kanye nobubanzi be-pulse ngeke kushintshwe. Ngakho-ke, ubukhulu bokulungiswa kwepharamitha buphakeme futhi ububanzi bubanzi. Ezimweni ezahlukene zokusetshenziswa kwezinto ezahlukene, ukuzivumelanisa nezimo kunamandla futhi isikhawu sewindi lenqubo sikhulu, esingahlangabezana nokuhlanzwa kwendawo kwezinto ezahlukahlukene.
▶ Ukuhlanzwa Kwe-Composite Fiber Laser
(isinqumo esingcono kakhulu sokususa upende)
Ukuhlanzwa kwe-laser ehlanganisiwe kusebenzisa i-laser eqhubekayo ye-semiconductor ukukhiqiza umphumela wokuqhuba ukushisa, ukuze i-substrate ezohlanzwa imunce amandla ukukhiqiza i-gasification, kanye ne-plasma cloud, futhi yakhe ingcindezi yokukhulisa ukushisa phakathi kwezinto zensimbi kanye nesendlalelo esingcolile, kunciphisa amandla okubopha phakathi kwesendlalelo. Lapho umthombo we-laser ukhiqiza umsebe we-laser we-pulse onamandla aphezulu, igagasi lokushaqeka lokudlidliza lizokhipha okunamathiselwe ngamandla okunamathela abuthakathaka, ukuze kufezwe ukuhlanzwa kwe-laser okusheshayo.
Ukuhlanzwa kwe-laser okuhlanganisiwe kuhlanganisa imisebenzi ye-laser eqhubekayo kanye ne-pulsed laser ngesikhathi esisodwa. Isivinini esiphezulu, ukusebenza kahle okuphezulu, kanye nekhwalithi yokuhlanza efanayo, ezintweni ezahlukene, kungasebenzisa amaza ahlukahlukene okuhlanza kwe-laser ngesikhathi esisodwa ukufeza injongo yokususa amabala.
Isibonelo, ekuhlanzweni kwezinto ezijiyile zokumboza nge-laser, ukukhishwa kwamandla amaningi e-laser eyodwa kukhulu futhi izindleko ziphezulu. Ukuhlanzwa okuhlanganisiwe kwe-laser e-pulsed kanye ne-semiconductor laser kungathuthukisa ngokushesha nangokuphumelelayo ikhwalithi yokuhlanza, futhi akubangeli umonakalo ku-substrate. Ekuhlanzweni kwezinto ezikhanyayo kakhulu nge-laser nge-aluminiyamu, i-laser eyodwa inezinkinga ezithile njengokukhanya okuphezulu. Ukusebenzisa ukuhlanza okuhlanganisiwe kwe-laser e-pulse kanye ne-semiconductor laser, ngaphansi kwesenzo sokudluliselwa kokushisa kwe-laser ye-semiconductor, kwandisa izinga lokumuncwa kwamandla kwengqimba ye-oxide ebusweni bensimbi, ukuze i-pulse laser beam ikwazi ukuhluba ungqimba lwe-oxide ngokushesha, kuthuthukiswe ukusebenza kahle kokususa ngempumelelo, ikakhulukazi ukusebenza kahle kokususa upende kukhushulwa izikhathi ezingaphezu kwezimbili.
▶ Ukuhlanzwa Nge-laser ye-CO2
(inketho engcono kakhulu yokuhlanza izinto ezingezona ezensimbi)
I-laser ye-carbon dioxide iyi-laser yegesi ene-CO2 gas njengento esebenzayo, egcwele i-CO2 gas kanye namanye amagesi asizayo (i-helium ne-nitrogen kanye nenani elincane le-hydrogen noma i-xenon). Ngokusekelwe kubude bayo obuhlukile, i-CO2 laser iyisinqumo esingcono kakhulu sokuhlanza ubuso bezinto ezingezona ezensimbi njengokususa iglue, i-coating kanye ne-inki. Isibonelo, ukusetshenziswa kwe-CO2 laser ukususa ungqimba lopende oluhlanganisiwe ebusweni be-aluminium alloy akulimazi ubuso befilimu ye-anodic oxide, futhi akunciphisi ukujiya kwayo.
▶ Ukuhlanza Nge-UV Laser
(isinqumo esingcono kakhulu sedivayisi kagesi eyinkimbinkimbi)
Ama-laser e-Ultraviolet asetshenziswa ku-laser micromachining ikakhulukazi afaka phakathi ama-laser e-excimer kanye nawo wonke ama-laser e-solid-state. Ubude be-laser ye-Ultraviolet bufushane, i-photon ngayinye ingaletha amandla aphezulu, ingaphula ngqo izibopho zamakhemikhali phakathi kwezinto. Ngale ndlela, izinto ezimboziwe zisuswa ebusweni ngesimo segesi noma izinhlayiya, futhi yonke inqubo yokuhlanza ikhiqiza amandla okushisa aphansi azothinta kuphela indawo encane ku-workpiece. Ngenxa yalokho, ukuhlanza i-laser ye-UV kunezinzuzo ezihlukile ekukhiqizeni okuncane, njengokuhlanza i-Si, i-GaN nezinye izinto ze-semiconductor, i-quartz, i-sapphire nezinye izinto ze-optical, kanye ne-polyimide (PI), i-polycarbonate (PC) nezinye izinto ze-polymer, kungathuthukisa ngempumelelo ikhwalithi yokukhiqiza.
I-laser ye-UV ibhekwa njengohlelo lokuhlanza i-laser olungcono kakhulu emkhakheni we-elekthronikhi enembile, ubuchwepheshe bayo bokucubungula "okubandayo" obuhlukile kakhulu abushintshi izakhiwo zomzimba zento ngesikhathi esifanayo, ubuso bomshini omncane wokucubungula, bungasetshenziswa kabanzi kwezokuxhumana, ekukhanyeni, ezempi, ophenyweni lobugebengu, ezimbonini zezokwelapha nakwezinye izindawo. Isibonelo, inkathi ye-5G idale isidingo semakethe sokucubungula i-FPC. Ukusetshenziswa komshini we-laser ye-UV kwenza kube nokwenzeka ukwenza umshini obandayo we-FPC nezinye izinto ngokunemba.
