Dhaimani "yekuveza" neraser: kukunda chinhu chakaoma zvikuru nechiedza
Dhaimanichinhu chakaoma kupfuura zvose zvakasikwa, asi hachisi zvishongo chete. Chinhu ichi chine simba rekupisa rinopetwa kashanu kupfuura mhangura, chinogona kutsungirira kupisa kwakanyanya uye mwaranzi, chinogona kutumira chiedza, kudzivirira kupisa, uye chinogona kutoshandurwa kuita semiconductor. Zvisinei, ndiwo "masimba makuru" aya anoita kuti dhaimani ive chinhu "chakanyanya kuoma" kugadzirisa - zvishandiso zvechinyakare hazvigone kuicheka kana kusiya mitswe. Zvakaitika kusvika pakatanga tekinoroji yelaser apo vanhu vakazowana kiyi yekukunda "mambo wezvinhu" uyu.
Sei laser ichigona "kucheka" dhaimani?
Fungidzira uchishandisa girazi rinokudza chiedza chezuva kuti ubatidze bepa. Nheyo yekugadzirisa dhaimani nelaser yakafanana, asi yakanyatsojeka. Kana dara relaser rine simba guru richivhenekera dhaimani, "kuchinja kweatomu yekabhoni" kunoitika nemicroscope:
1. Dhaimani inoshanduka kuita girafiti: Simba relaser rinoshandura chimiro chedhaimani pamusoro (sp³) kuita girafiti yakapfava (sp²), sezvinoita dhaimani "inoparara" pakarepo kuita penzura.
2. Graphite "inopwanyika": girafu regirafu rinonyungudika kana kupisa kwakanyanya kana kuti rinochekwa neokisijeni, zvichisiya zviratidzo zvekugadzirisa zvakanyatsonaka. 3. Kubudirira kukuru: kukanganisa Mudzidziso, dhaimani rakakwana rinogona kugadziriswa chete ne ultraviolet laser (wavelength <229 nm), asi muchokwadi, madhaimani ekugadzira anogara aine zvikanganiso zvidiki (senge tsvina nemiganhu yezviyo). Kukanganisa uku kwakafanana ne "maburi" anobvumira chiedza chegirini (532 nm) kana infrared laser (1064 nm) kuti chinyudzwe. Masayendisiti anogona kuto "raira" laser kuti igadzire pateni chaiyo padhaimani nekudzora kupararira kwezvikanganiso.
Rudzi rweLaser: Kushanduka kubva pakuva "choto" kuenda kukuva "banga rechando"
Kugadziriswa neLaser kunobatanidza masisitimu ekudzora nhamba dzemakombiyuta, masisitimu epamusoro ekuona, uye nzvimbo yekushanda yakanyatsogadzirwa uye otomatiki kuti igadzire nzvimbo yekutsvagisa nekugadzira. Inoshandiswa pakugadzirisa madhaimani, inogona kuwana kugadziriswa kwakanaka uye kwakanyatsojeka.
1. Kugadziriswa kwelaser ye microsecond Upamhi hwemapundu elaser ye microsecond hwakafara uye hunowanzo kukodzera kugadziriswa zvisina kunaka. Tekinoroji yekukiya mode isati yatanga, mapundu elaser aive akawanda mu microsecond ne nanosecond range. Parizvino, kune mishumo mishoma pamusoro pekugadzirisa zvakananga madhaimani ne microsecond lasers, uye mazhinji acho anotarisa pamunda wekushandisa mapundu e back-end.
2. Kugadziriswa kweNanosecond laser MaNanosecond lasers parizvino ane mugove mukuru wemusika uye ane mabhenefiti ekugadzikana kwakanaka, mutengo wakaderera, uye nguva pfupi yekugadzirisa. Anoshandiswa zvakanyanya mukugadzira mabhizinesi. Zvisinei, maitiro ekubvisa nanosecond laser anoparadza sampuli zvakanyanya, uye chiratidzo chikuru ndechekuti kugadzirwa kwacho kunogadzira nzvimbo yakakura inokanganiswa nekupisa.
3. Kugadziriswa kwePicosecond laser Kugadziriswa kwePicosecond laser kuri pakati pe nanosecond laser thermal equilibrium ablation uye femtosecond laser cold processing. Nguva yekurova kwemoyo inoderedzwa zvakanyanya, izvo zvinoderedza zvikuru kukuvara kunokonzerwa nenzvimbo inokanganiswa nekupisa.
4. Kugadziriswa kweFemtosecond laser Tekinoroji yeUltrafast laser inounza mikana yekugadzirisa dhaimani, asi mari yakawanda uye kugadzirisa kwefemtosecond lasers kunoderedza kusimudzirwa kwenzira dzekugadzirisa. Parizvino, tsvakiridzo dzakawanda dzine chekuita nadzo dzichiri muchikamu cherabhoritari.
Mhedziso
Kubva pa "kusagona kucheka" kusvika pa "kuveza sezvaunoda", tekinoroji yelaser yagadziradhaimani haisisiri "vhasi" rakavharirwa murabhoritari. Nekuvandudzwa kwetekinoroji, mune ramangwana tinogona kuona: machipisi edhaimani anobvisa kupisa mumafoni, makombiyuta equantum achishandisa madhaimani kuchengetera ruzivo, uye kunyange madhiimani biosensors akaiswa mumuviri wemunhu… Kutamba uku kwechiedza nedhaimani kuri kuchinja hupenyu hwedu.
