Sisitemu za laser zigezweho - kuva kuri laser za femtosecond pulse zikoreshwa mu kubaga amaso no mu gutunganya ibikoresho kugeza kuri laser za picosecond muri semiconductor scribing na ultrafast spectroscopy - zigomba gushyira imirasire n'ibikoresho byazo mu buryo buhuye n'ubuziranenge bw'ahantu hapimwe muri micrometers, rimwe na rimwe na nanometers. Fiziki y'urumuri ishobora kuba nziza cyane, ariko imiterere ishyira ibice by'amajwi n'ibikorwa igomba kuba ifite ubuziranenge bungana.
Muri uru rwego rw'ikoreshwa rya laser rigezweho, igice kimwe kigaragara kenshi: urwego rwa granite rukoresha umwuka. Uruhurirane rusa n'aho rutandukanye n'urundi - ibuye rya kera rihujwe n'ikoranabuhanga rigezweho ryo gukoresha umwuka - urwego rwa granite rukoresha umwuka rwabaye igipimo ngenderwaho mu buryo bwa laser rigezweho kuko rukemura, kurusha ubundi buryo ubwo aribwo bwose, ibibazo by'ibanze by'ubuhanga byo kugenda nta gushwanyagurika, kwitandukanya n'ibintu bihindagurika, no kudahindagurika mu buryo bungana.
Iyi nkuru irasuzuma amahame y’ubuhanga mu bijyanye n’ibyiciro bya granite itwara umwuka, isobanura impamvu granite n’ikoreshwa ry’umwuka bigira ubufatanye butanga umusaruro, kandi ikurikirana ikoreshwa ryabyo mu buryo bugezweho bwa laser.
Ibyuma by'umwuka: Ingendo idahindagurika ku gipimo cya Nanometero
Ibyuma bisanzwe byo kuzunguruka - imipira cyangwa imigozi igenda mu nzira zo gusiganwa - ni byo bintu bikoreshwa mu mikorere ya mashini. Ni ibyizerwa, bito, kandi bishobora gutwara umutwaro mwinshi. Ariko bifite imbogamizi y'ibanze: bigaragaza imyitwarire yo gusimbuka nk'iy'umugozi, uburyo budasanzwe bwo kugenda butera umwanya wo kuzunguruka kw'umugozi mu gihe cyo kugenda kwa mbere, kandi uko kuzunguruka kw'ibintu bizunguruka bigenda bihura.
Ku bipimo bya macroscopic, gucengera kw'inkoni ni ikibazo gito. Ku bipimo bya nanometer, ni imbogamizi y'ibanze ku kugenda neza no gusubiramo. Sisitemu yo gushyira ibintu aho bigomba kuba bigeze ku gucengera kw'inkoni ya nanometer 10 ntishobora kwihanganira icyuma kigaragaza gucengera kw'inkoni ya nanometer 100 mu gihe cyo gutangira kugenda.
Udupira tw’umwuka dukuraho gucika kw’uduti burundu dusimbuza icyuma gikonjesha umwuka — ubusanzwe gifite ubugari bwa mikorometero 5–15 — gitandukanya burundu igice cyo kwimuka n’igice cyo kureberaho. Iyo nta gice cyo kwimuka cy’umwuka, nta gucika kw’uduti mu buryo busanzwe, nta gucika kw’uduti, kandi nta kwangirika kw’uduti. Igice cyo kwimuka kigenda mu kirere, kandi ingendo zishobora kuba nziza kandi zigasubiramo nkuko ubuso bwo kureberaho bubyemera.
Ingaruka zo kugenda neza ni nyinshi. Icyiciro cyo gutwara umwuka gishobora kugenda mu ntera ya nanometero hamwe no gusubiramo ibintu bishobora guteza ikibazoibikoresho byo gupimabyakoreshejwe mu kubigenzura. Umuvuduko ushobora kugenzurwa ukagera ku kigero cya 0.01% ku muvuduko uva kuri mikorometero ku isegonda ukagera kuri metero ku isegonda. Ingufu ubwazo zitanga imbaraga nta tandukaniro ry’ingufu mu ngendo zazo - ikintu cy’ingenzi cyane kuri sisitemu za laser aho ihungabana ry’imbaraga ryatera amajwi ya mekanike n’aho urumuri ruherereye.
Impamvu Granite ari yo buso bwiza bwo kugaragaza ubwiza bw'umwuka
Icyiciro cyo gutwara umwuka kiba cyiza kimwe n'ubuso bw'aho kigendera. Ubuso bw'aho kigera bugomba kuba bwujuje ibisabwa byinshi icyarimwe.
Ubwa mbere, ubugari. Ibyuma by'umwuka bifatwa n'amakosa yo mu buso kuko ubugari bwa filime y'umwuka (ubusanzwe ni 5–15 μm) bungana n'ubugari bw'ubugari bw'ubuso bushobora kugerwaho mu gusya no gusimbuka neza. Ubugari bw'ubuso bwa 1 μm butera ihinduka rya 1 μm mu cyuho cy'umwuka - bihindura ikosa ryo mu mwanya ugororotse wa 1 μm mu cyiciro. Ku buryo sisitemu igamije ubwiza bwa nanometero 100, ubuso bw'aho bugarukira bugomba kuba buringaniye kugeza kuri nanometero 100 mu rugero rwuzuye rw'urugendo.

Ubukana bwinshi bw'ubuso bubangamira icyuma cy'umwuka, bugatera impinduka mu gitutu, kandi bugashyira urusaku mu migendekere y'urubyiniro. Ubukana bw'ubukana bw'ubuso buri munsi ya Ra 0.05 μm (nanometero 50) busanzwe bukenewe kugira ngo habeho uburyo bwiza bwo gukoresha icyuma cy'umwuka.
Icya gatatu, gukomera no kudashira. Nubwo ibyuma bikingira umwuka byagenewe kwirinda gukoraho, rimwe na rimwe bishobora guterana mu gihe cyo gutangira, guhagarara byihutirwa, cyangwa igihe umwuka wangiritse. Ubuso bw'aho bigarukira bugomba kuba bukomeye bihagije kugira ngo burinde gutsindwa cyangwa kwangirika kw'ibi bintu. Granite, ifite ubukana bwa Mohs bwa 6-7 (iterwa ahanini n'ingano yayo ya quartz), itanga ubukana bwiza cyane bwo kudashira kurusha aluminiyumu cyangwa pulasitiki nyinshi, kandi igereranywa cyangwa irusha icyuma gikomeye kuri iyo ntego.
Icya kane, ubushyuhe buhamye. Icyuho cy'umwuka mu gipimo cy'umwuka ni igipimo cy'ubushyuhe gigenzurwa neza. Kwaguka k'ubushyuhe buhindura icyuho bihindura ubukana bw'igipimo n'ubushobozi bw'umutwaro - kandi bihindura aho urwego ruherereye. Igipimo cyo kwaguka k'ubushyuhe cya Granite kiri hasi kandi gihoraho, hamwe n'ubushyuhe bwayo bwinshi (gusubiza buhoro buhoro ku mpinduka z'ubushyuhe), bitanga ubuziranenge busabwa na sisitemu za laser zihamye.
Icya gatanu, imiterere idakoresha ingufu za rukuruzi n'izidakoresha ingufu za rukuruzi. Sisitemu nyinshi zo gushyiramo ingufu za laser zikoresha moteri zikoresha umurongo ugororotse, zitanga ingufu za rukuruzi. Imashini ikoresha ingufu za rukuruzi ya ferromagnetike yakorana n'izi ngufu, bigatuma habaho ihungabana ry'imbaraga kandi bishobora gutera guhindagurika kw'igenzura uko amateka ya rukuruzi y'ibintu ahinduka. Imiterere ya Granite idakoresha ingufu za rukuruzi kandi idakoresha ingufu za rukuruzi ikuraho burundu ubwo buryo bwo gukorana.
Sisitemu za Laser za Femtosecond: Ibisabwa cyane ku buryo bwo gushyira ahantu hizewe
Lazeri ya Femtosecond ikora imivuduko iri munsi ya picosegonda 1 - kimwe cya miliyari cya miliyoni y'isegonda. Muri ibi bihe, imikoranire ya lazeri n'ibintu bitandukanye cyane no gutunganya lazeri bisanzwe: ibikoresho bigabanuka vuba cyane ku buryo ubushyuhe butagira umwanya wo gukwirakwira mu bikoresho bikikije, bigatuma hakorwa neza imiterere y'ahantu habangamiwe n'ubushyuhe hapimwa muri nanometero aho kuba muri milimetero.
Ubu bushobozi bukoreshwa mu kubaga cornea (LASIK), gukoresha neza ibice by'ikoranabuhanga, imiterere y'ibikoresho byo gukoresha fotoniki, no gukora imirasire ya ultraviolet (EUV) yo gukoresha lithography y'ikizakurikira. Muri buri koreshwa, aho laser ishyirwa ugereranije n'aho ikorera hagomba kugenzurwa hakurikijwe ubushobozi bungana n'ingano y'aho laser iherereye - akenshi ni mikorometero 1-10.
Sisitemu yo gushyiramo ibintu ku cyiciro cya laser ya femtosecond igomba kugera ku buziranenge bwa μm 1–10 mu gihe cy’ingendo zishobora kugera kuri mm 300 cyangwa zirenga - intera ihindagurika ya 1:30.000 cyangwa irenga. Igomba kubikora ifite umuvuduko uhamye bihagije kugira ngo itange ubujyakuzimu bumwe bw’ibintu byose ku gice cy’akazi. Kandi igomba kubigeraho mu ipaki nto, ijyanye n’icyumba gisukuye ihuzwa na sisitemu yo gutanga urumuri ya laser.
Ibyiciro bya granite bifite umwuka bikemura ibi byose bisabwa. Ibyuma bifite umwuka bitanga umuvuduko woroshye kandi utagira imivurungano ikenewe kugira ngo umuvuduko umwe ugere ku muvuduko umwe. Ishingiro rya granite ritanga ubugari n'ubukonje bikenewe kugira ngo habeho ubuziranenge. Ubushyuhe buhuriweho bukomeza imiterere ya laser kuva ku gikoresho kugeza ku gikoresho uko gishyuha kandi kikagera ku buringanire.
Sisitemu za Picosecond Laser mu nganda z'ibikoresho by'ikoranabuhanga
Laser za Picosecond zifata umwanya wo hagati ya nanosecond (pulsed isanzwe) na laser za femtosecond mu bijyanye n'igihe cy'impinduka n'imiterere yo kuzitunganya. Zikoreshwa cyane mu gukora ibikoresho by'ikoranabuhanga birimo PCB binyuze mu gucukura, gushushanya uturemangingo tw'izuba duto, gukata ikirahure na safiro ku bikoresho by'ikoranabuhanga, no gushyira ikimenyetso no gukurikirana ibice by'ikoranabuhanga.
Muri ubu buryo bwo gukoresha mu nganda, ubushobozi bwo gukoresha ibintu ni ingenzi cyane — uburyo bwo gushyira ibintu mu mwanya bugomba kugenda vuba hagati y’ibintu mu gihe bukomeza gukora neza kugira ngo bugere ku ntego aho zigomba kugera. Guhuza umuvuduko mwinshi n’ubuziranenge bwinshi ni byo by’ingenzi cyane: imiterere y’umwuka ituma umuvuduko mwinshi utagira ikosa riterwa n’umuvuduko, mu gihe ubukana n’ubudahangarwa bya granite bibuza imbaraga za mekanike zishobora kugabanya ubuziranenge ku muvuduko mwinshi.
Indi nyungu mu nganda zikora ibikoresho by'ikoranabuhanga ni uko sisitemu yo gutwara ibintu mu kirere ishobora gusubiramo mu gihe cy'ingendo za miliyari. Imashini icukura PCB itunganya imbaho ibihumbi ku munsi ikora uruziga rwinshi mu gihe cyose ikora. Imiterere y'ubwikorezi bw'umwuka isobanura ko ubuziranenge bw'iyi sisitemu mu mwaka wa gatanu ari kimwe n'ubwo ku munsi wa mbere - ikintu kidashobora kugereranywa n'ubwikorezi bw'ibintu bizunguruka, bugaragaza kwangirika buhoro buhoro no kwangirika uko igihe kigenda gihita.
Ibibazo n'ibisubizo byo guhuza
Gushyiramo icyiciro cya granite gitera umwuka muri sisitemu yo gukoresha laser neza bisaba ibintu byinshi by’ubuhanga uretse icyiciro ubwacyo. Hakenewe umwuka mwiza kandi wumye utangwa ku gitutu gigenzurwa - akenshi uyungururwa kugira ngo ube isuku yo mu cyiciro cya 0 kandi umuvuduko ugenzurwe kugeza kuri ± 0.1% cyangwa birenga. Sisitemu yo gutanga umwuka ntigomba gushyiramo imitingito cyangwa imivuduko y’umuvuduko ikwirakwira mu cyiciro.
