Irhasi edibeneyo yeLaseribhekisa kumbindi osebenzayo owenziwe ngokuxuba iigesi ezininzi kumyinge othile ukuze kuphunyezwe iimpawu ezithile zokuphuma kwelaser ngexesha lokwenziwa kwelaser kunye nenkqubo yokusetyenziswa. Iindidi ezahlukeneyo zeelaser zifuna ukusetyenziswa kweegesi ezixutywe ngelaser ezinamacandelo ahlukeneyo. Oku kulandelayo yintshayelelo eneenkcukacha zakho:

Iintlobo eziqhelekileyo kunye nezicelo

CO2 laser igesi exutywe

Ikakhulu yenziwe ngecarbon dioxide (CO2), initrogen (N2) kunye nehelium (HE). Kwintsimi yokucutshungulwa kwamashishini, njengokusika, i-welding kunye nokunyangwa kwendawo, i-carbon dioxide lasers isetyenziswa ngokubanzi. Phakathi kwabo, i-carbon dioxide yeyona nto iphambili yokuvelisa i-lasers, i-nitrogen inokukhawulezisa inguqu yezinga lamandla e-carbon dioxide iimolekyuli kunye nokwandisa amandla emveliso ye-laser, kunye ne-helium inceda ukutshabalalisa ubushushu kunye nokugcina ukuzinza kokukhutshwa kwegesi, ngaloo ndlela kuphuculwe umgangatho we-laser beams.

Excimer laser exutywe igesi

Ixutywe kwiigesi ezinqabileyo (ezifana ne-argon (AR),ikripton (KR), xenon (XE)) kunye nezinto ze-halogen (ezifana ne-fluorine (F), i-chlorine (CL)), njengeARF, KRF, XeCl,njl. Olu hlobo lwe-laser luhlala lusetyenziswa kwi-teknoloji ye-photolithography. Kwimveliso ye-chip ye-semiconductor, inokufikelela kwi-high-resolution transfer graphic; iphinda isetyenziswe kwi-ophthalmic surgery, njenge-excimer laser in situ keratomileusis (LASIK), ekwazi ukusika ngokuchanekileyo izicubu ze-cornea kunye nombono ochanekileyo.

I-Helium-neonigesi laserumxube

Ngumxube wei-heliumkwayeneonkumlinganiselo othile, ngokwesiqhelo phakathi kwe-5:1 kunye ne-10:1. I-laser ye-Helium-neon yenye yee-laser zerhasi zokuqala, ene-wavelength ye-632.8 nanometers, ekukukhanya okubomvu okubonakalayo. Ihlala isetyenziswa kwimiboniso ye-optical demonstrations, i-holography, i-laser yokwalatha kunye neminye imimandla, efana nokulungelelaniswa kunye nokubeka indawo kulwakhiwo, kunye nakwizikena zebhakhowudi kwiivenkile ezinkulu.

Imiqathango yokusetyenziswa

Iimfuno zokucoceka okuphezulu: Ukungcola kumxube wegesi ye-laser kuya kuchaphazela amandla okukhutshwa kwe-laser, ukuzinza kunye nomgangatho we-beam. Ngokomzekelo, umswakama uya kutshabalalisa amacandelo angaphakathi e-laser, kwaye i-oksijini iya ku-oxidize i-optical components kunye nokunciphisa ukusebenza kwazo. Ngoko ke, ukucoceka kwegesi ngokuqhelekileyo kufuna ukufikelela ngaphezu kwe-99.99%, kwaye izicelo ezikhethekileyo zifuna ngaphezu kwe-99.999%.

Umlinganiselo ochanekileyo: Umlinganiselo wecandelo ngalinye legesi unempembelelo enkulu ekusebenzeni kwe-laser, kwaye umlinganiselo ochanekileyo kufuneka ube ngokungqongqo ngokuhambelana neemfuno zoyilo lwe-laser. Ngokomzekelo, kwi-carbon dioxide laser, utshintsho kumlinganiselo we-nitrogen kwi-carbon dioxide kuya kuchaphazela amandla okukhutshwa kwe-laser kunye nokusebenza kakuhle.

Ukugcinwa okukhuselekileyo kunye nokusetyenziswa: Ezinyeiigesi ezixutywe nge-laserziyityhefu, zidle, okanye zinokutsha kwaye ziyadubula. Umzekelo, irhasi yefluorine kwi-laser ye-excimer inetyhefu kakhulu kwaye iyadleka. Kufuneka kuthathwe amanyathelo angqongqo okhuseleko ngexesha lokugcinwa kunye nokusetyenziswa, njengokusebenzisa izitya zokugcina ezivaliweyo, ezixhotyiswe ngezixhobo zokungenisa umoya kunye nezixhobo zokubona ukuvuza kwegesi, njl.
