CO2 Laser agwakọta gas

Ihe mejupụtara ya bụ carbon dioxide (CO2), nitrogen (N2) na helium (HE). N'ihe gbasara nhazi ụlọ ọrụ, dị ka ịkpụ, ịgbado ọkụ na ọgwụgwọ elu, a na-ejikarị laser carbon dioxide eme ihe. N'ime ha, carbon dioxide bụ isi ihe na-emepụta lasers, nitrogen nwere ike mee ka mgbanwe nke ike nke mkpụrụ ndụ carbon dioxide dịkwuo elu ma mee ka ike mmepụta laser dịkwuo elu, na helium na-enyere aka ịgbasa okpomọkụ ma nọgide na-enwe nkwụsi ike nke nkwụsị gas, si otú ahụ na-eme ka ogo laser dị elu.

Excimer laser agwakọta gas

Ngwakọta sitere na gas na-adịghị ahụkebe (dị ka argon (AR),krypton (KR), xenon (XE)) na ihe halogen (dị ka fluorine (F), chlorine (CL)), dị kaARF, KRF, XeCl,wdg A na-ejikarị ụdị laser a eme ihe na teknụzụ fotolithography. Na semiconductor mgbawa n'ichepụta, ọ nwere ike nweta elu-mkpebi graphic nyefe; A na-ejikwa ya na ịwa ahụ anya, dị ka excimer laser in situ keratomileusis (LASIK), nke nwere ike ibelata anụ ahụ cornea n'ụzọ ziri ezi ma dozie ọhụụ.

Ọ bụ ngwakọta nkeheliumnaneonn'otu akụkụ, na-adịkarị n'etiti 5:1 na 10:1. Laser Helium-neon bụ otu n'ime lasers gas mbụ, nke nwere ogologo nrụpụta nke 632.8 nanometers, nke bụ ìhè a na-ahụ anya na-acha ọbara ọbara. A na-ejikarị ya eme ihe ngosi anya, holography, laser pointing na mpaghara ndị ọzọ, dị ka itinye n'ọnọdụ na ntinye n'ime ihe owuwu, yana n'ime ihe nyocha koodu na ụlọ ahịa.

Akpachara anya maka ojiji

Achọrọ ịdị ọcha dị elu: Ihe ndị na-adịghị ọcha na ngwakọta gas laser ga-emetụta ike mmepụta laser, nkwụsi ike na àgwà beam. Dịka ọmụmaatụ, mmiri ga-emebi ihe ndị dị n'ime nke laser ahụ, oxygen ga-eme ka ihe ndị ahụ na-ahụ anya na-ebelata ma belata ọrụ ha. Ya mere, gas dị ọcha na-achọkarị iru karịa 99.99%, na ngwa pụrụ iche ọbụna chọrọ karịa 99.999%.

Ogo nke ziri ezi: Oke nke akụrụngwa gas ọ bụla nwere mmetụta dị ukwuu na arụmọrụ laser, yana oke nha kwesịrị ịdị n'ụzọ kwekọrọ n'ihe achọrọ imebe laser. Dịka ọmụmaatụ, na laser carbon dioxide, mgbanwe nke nitrogen na carbon dioxide ga-emetụta ike mmepụta laser na arụmọrụ.

Nchekwa na ojiji nke ọma: Ụfọdụgas agwakọta laserna-egbu egbu, na-emebi emebi, ma ọ bụ na-ere ọkụ na ihe mgbawa. Dịka ọmụmaatụ, gas fluorine dị na laser excimer na-egbu egbu ma na-emebi emebi. A ghaghị iwere usoro nchekwa siri ike n'oge nchekwa na ojiji, dị ka iji ihe nchekwa nke ọma kpuchiri ekpuchi, ejiri ngwá ọrụ ikuku na ngwaọrụ nchọpụta ikuku gas, wdg.
