Gaurayen iskar gas na Laser CO2

Mafi yawansu sun ƙunshi carbon dioxide (CO2), nitrogen (N2) da helium (HE). A fannin sarrafa masana'antu, kamar yankewa, walda da kuma maganin saman ƙasa, ana amfani da lasers na carbon dioxide sosai. Daga cikinsu, carbon dioxide shine babban abu don samar da lasers, nitrogen na iya hanzarta canjin matakin makamashi na ƙwayoyin carbon dioxide da kuma ƙara ƙarfin fitar da laser, kuma helium yana taimakawa wajen wargaza zafi da kuma kiyaye daidaiton fitar da iskar gas, ta haka ne inganta ingancin hasken laser.

Gaurayen iskar gas na Excimer Laser

Gauraye da iskar gas mai wuya (kamar argon (AR),krypton (KR), xenon (XE)) da abubuwan halogen (kamar fluorine (F), chlorine (CL)), kamarARF, KRF, XeCl,Da sauransu. Ana amfani da wannan nau'in laser sau da yawa a fasahar photolithography. A cikin kera guntu na semiconductor, yana iya cimma babban ƙuduri na zane-zane; ana kuma amfani da shi a cikin tiyatar ido, kamar laser excimer in situ keratomileusis (LASIK), wanda zai iya yanke kyallen cornea daidai da kuma daidaita gani.

Helium-neoniskar lasercakuda

Cakuda ce taheliumkumaneona cikin wani rabo, yawanci tsakanin 5:1 da 10:1. Laser ɗin Helium-neon yana ɗaya daga cikin na'urorin laser na gas na farko, tare da tsawon fitowar nanomita 632.8, wanda shine hasken ja da ake iya gani. Sau da yawa ana amfani da shi a cikin nunin gani, holography, nunin laser da sauran fannoni, kamar daidaitawa da matsayi a cikin gini, da kuma a cikin na'urorin daukar hoto na barcode a manyan kantuna.

Gargaɗi don amfani

Bukatun tsarki mai yawa: Datti a cikin cakuda iskar gas ta laser zai shafi ƙarfin fitarwar laser, kwanciyar hankali da ingancin katako. Misali, danshi zai lalata sassan ciki na laser, kuma iskar oxygen zai lalata sassan gani kuma ya rage aikinsu. Saboda haka, tsarkin iskar gas yawanci yana buƙatar isa fiye da 99.99%, kuma aikace-aikace na musamman ma suna buƙatar fiye da 99.999%.

Daidaitaccen rabo: Rabon kowanne bangaren iskar gas yana da tasiri mai yawa akan aikin laser, kuma ainihin rabon dole ne ya kasance daidai da buƙatun ƙirar laser. Misali, a cikin laser carbon dioxide, canje-canje a cikin rabon nitrogen zuwa carbon dioxide zai shafi ƙarfin fitarwa na laser da inganci.

Ajiya mai aminci da amfani: Wasuiskar gas gauraye ta lasersuna da guba, masu lalata, ko masu kama da wuta da kuma fashewa. Misali, iskar fluorine da ke cikin laser na excimer yana da guba sosai kuma yana lalata. Dole ne a ɗauki tsauraran matakan tsaro yayin ajiya da amfani, kamar amfani da kwantena na ajiya da aka rufe sosai, sanye da kayan aikin iska da na'urorin gano ɓullar iska, da sauransu.
