Igesi exutyiweyo yelaseribhekisa kwindawo yokusebenza eyenziwe ngokuxuba iigesi ezininzi ngomlinganiselo othile ukuze kufezekiswe iimpawu ezithile zokukhupha i-laser ngexesha lokuveliswa kwe-laser kunye nenkqubo yokufaka isicelo. Iintlobo ezahlukeneyo ze-laser zifuna ukusetyenziswa kweegesi ezixutyiweyo ze-laser ezineenxalenye ezahlukeneyo. Oku kulandelayo kwazisa ngeenkcukacha:

Iindidi eziqhelekileyo kunye nezicelo

Igesi exutyiweyo ye-CO2 laser

Ikakhulu yenziwe ngekhabhoni diokside (CO2), initrogen (N2) kunye nehelium (HE). Kwicandelo lokucubungula imboni, njengokusika, ukuwelda kunye nonyango lomphezulu, iilaser zekhabhoni diokside zisetyenziswa kakhulu. Phakathi kwazo, ikhabhoni diokside yeyona nto iphambili ekuveliseni iilaser, initrogen inokukhawulezisa utshintsho lwamandla kwiimolekyuli zekhabhoni diokside kwaye yonyuse amandla okukhupha ilaser, kwaye ihelium inceda ekususeni ubushushu kwaye igcine uzinzo lokukhupha igesi, ngaloo ndlela iphucula umgangatho wemitha yelaser.

Igesi exutyiweyo yelaser ye-Excimer

Ixutywe neegesi ezingaqhelekanga (ezifana ne-argon (AR),iKrypton (KR), i-xenon (XE)kunye nezinto zehalogen (ezifana ne-fluorine (F), i-chlorine (CL)), ezifanaI-ARF, i-KRF, i-XeCl,njl. Olu hlobo lwelaser lusetyenziswa rhoqo kwitekhnoloji ye-photolithography. Kwimveliso yeetshiphusi ze-semiconductor, inokufikelela kudluliselo lwegraphic olunesisombululo esiphezulu; ikwasetyenziswa nakutyando lwamehlo, njenge-laser ye-excimer in situ keratomileusis (LASIK), enokunqumla ngokuchanekileyo izicubu ze-cornea kwaye ibone kakuhle.

I-Helium-neonigesi yelaserumxube

Ngumxube wei-heliumkwayei-neonkwisilinganiso esithile, ngesiqhelo phakathi kwe-5:1 kunye ne-10:1. I-laser ye-Helium-neon yenye yee-laser zegesi zokuqala, enobude bomda obuphumayo obuyi-632.8 nanometers, obukukhanya okubomvu okubonakalayo. Ihlala isetyenziswa kwimiboniso ye-optical, i-holography, i-laser pointing kunye neminye imimandla, efana nokulungelelaniswa kunye nokubekwa kwindawo yokwakha, kunye nakwi-barcode scanners kwiivenkile ezinkulu.

Amanyathelo okusebenzisa

Iimfuneko zobunyulu obuphezulu: Ukungcola kumxube wegesi yelaser kuya kuchaphazela amandla okukhupha ilaser, uzinzo kunye nomgangatho wemitha. Umzekelo, ukufuma kuya kutshabalalisa izinto zangaphakathi zelaser, kwaye ioksijini iya kunyibilikisa izinto ezibonakalayo kwaye inciphise ukusebenza kwazo. Ke ngoko, ubunyulu begesi budla ngokufuna ukufikelela ngaphezulu kwe-99.99%, kwaye izicelo ezikhethekileyo zifuna ngaphezulu kwe-99.999%.

Umlinganiselo ochanekileyo: Umlinganiselo wecandelo ngalinye legesi unempembelelo enkulu ekusebenzeni kwelaser, kwaye umlinganiselo ochanekileyo kufuneka uhambelane ngokungqongqo neemfuno zoyilo lwelaser. Umzekelo, kwilaser yekhabhoni diokside, utshintsho kumlinganiselo wenitrogen kwikhabhoni diokside luya kuchaphazela amandla kunye nokusebenza kakuhle kwelaser.

Ukugcinwa nokusetyenziswa okukhuselekileyo: Ezinyeiigesi ezixutyiweyo nge-laserziyingozi, ziyabola, okanye ziyatsha kwaye ziyaqhuma. Umzekelo, igesi ye-fluorine kwi-laser ye-excimer iyingozi kakhulu kwaye iyabola. Amanyathelo okhuseleko angqongqo kufuneka athathwe ngexesha lokugcina nokusebenzisa, njengokusebenzisa izikhongozeli zokugcina ezivalwe kakuhle, ezixhotyiswe ngezixhobo zokungenisa umoya kunye nezixhobo zokubona ukuvuza kwegesi, njl.
