Laser "saƙa" lu'u-lu'u: cin nasara mafi wuya abu tare da haske

Diamondshine abu mafi wuya a yanayi, amma ba kawai kayan ado ba. Wannan abu yana da ƙarfin wutar lantarki sau biyar da sauri fiye da jan karfe, yana iya jure matsanancin zafi da radiation, yana iya watsa haske, rufewa, har ma yana iya canzawa zuwa semiconductor. Duk da haka, waɗannan "mafi iko" ne suka sa lu'u-lu'u ya zama kayan "mafi wuya" don sarrafawa - kayan aikin gargajiya ko dai ba za su iya yanke shi ba ko barin fasa. Sai da zuwan fasahar Laser da mutane a karshe suka sami mabuɗin cin nasarar wannan "sarkin kayan aiki".

Ka yi tunanin yin amfani da gilashin ƙarawa don mayar da hankali ga hasken rana don kunna takarda. Ka'idar lu'u-lu'u sarrafa Laser iri ɗaya ce, amma mafi daidai. Lokacin da katako mai ƙarfi na Laser ya haskaka lu'u-lu'u, abin da ba a iya gani ba yana faruwa "carbon atom metamorphosis":

1. Lu'u-lu'u yana juyewa zuwa graphite: Ƙarfin laser yana canza tsarin lu'u-lu'u (sp³) zuwa graphite mai laushi (sp²), kamar dai yadda lu'u-lu'u ya zama "lalacewa" a cikin fensir gubar.

2. Graphite an "kore": graphite Layer sublimates a high zafin jiki ko an etched da oxygen, barin daidai aiki alamomi. 3. Maɓalli mai mahimmanci: lahani A ka'idar, cikakkiyar lu'u-lu'u za a iya sarrafa shi ta hanyar laser ultraviolet (tsawon tsayi <229 nm), amma a gaskiya, lu'u-lu'u na wucin gadi koyaushe suna da ƙananan lahani (kamar ƙazanta da iyakokin hatsi). Waɗannan lahani suna kama da “ramuka” waɗanda ke ba da izinin ɗaukar haske na yau da kullun (532 nm) ko Laser infrared (1064 nm) don ɗauka. Masana kimiyya na iya ma "umarni" Laser don sassaƙa takamaiman tsari akan lu'u-lu'u ta hanyar daidaita rarraba lahani.

Nau'in Laser: Juyin Halitta daga "tanderu" zuwa "wukar kankara"

Laser aiki hada kwamfuta lamba kula da tsarin, m Tantancewar tsarin, da kuma high-madaidaici da sarrafa kansa workpiece matsayi don samar da wani bincike da samar da cibiyar sarrafa. Aiwatar da sarrafa lu'u-lu'u, zai iya cimma ingantaccen aiki mai inganci da inganci.

1. Microsecond Laser aiki Microsecond Laser bugun jini nisa ne fadi da kuma yawanci dace da m aiki. Kafin bullowar fasahar kulle yanayin, fitilun Laser sun kasance mafi yawa a cikin microsecond da nanosecond. A halin yanzu, akwai 'yan rahotanni game da sarrafa lu'u-lu'u kai tsaye tare da laser microsecond, kuma yawancinsu suna mayar da hankali kan filin aikace-aikacen aiki na baya.

2. Nanosecond Laser sarrafa Nanosecond Laser a halin yanzu mamaye babban kasuwa rabo kuma suna da abũbuwan amfãni daga mai kyau kwanciyar hankali, low cost, da kuma gajeren lokaci aiki.
