Iimpawu eziphambili ze-laser gain medium

Ziziphi iimpawu eziphambili ze-laser gain media?

I-laser gain medium, eyaziwa ngokuba yi-laser working substance, ibhekisa kwinkqubo yezinto ezisetyenziselwa ukufezekisa ukuguqulwa kwenani lamasuntswana kunye nokuvelisa imitha evuselelweyo ukuze kufezekiswe ukwandiswa kokukhanya. Yinxalenye ephambili ye-laser, ephethe inani elikhulu lee-athomu okanye iimolekyuli, ezi atomu okanye iimolekyuli phantsi kokuvuselelwa kwamandla angaphandle, zinokutshintshela kwimeko yovuyo, kwaye ngemitha evuselelweyo ikhuphe ii-photons, ngaloo ndlela zenze i-isibane selaser. Isixhobo sokufumana i-laser sinokuba yinto eqinileyo, elulwelo, yegesi okanye ye-semiconductor.
Kwi-solid-state lasers, i-gain media esetyenziswa kakhulu ziikristale ezifakwe ii-ions zomhlaba ezingaqhelekanga okanye ii-ions ze-transition metal, ezifana neekristale ze-Nd:YAG, iikristale ze-Nd:YVO4, njl. Kwi-liquid lasers, iidayi ze-organic zihlala zisetyenziswa njenge-gain media. Ii-gas lasers zisebenzisa igesi njenge-gain medium, njenge-carbon dioxide gas kwi-carbon dioxide lasers, kunye ne-helium kunye ne-neon gas kwi-helium-neon lasers.Iileyiza ze-semiconductorsebenzisa izixhobo ze-semiconductor njengesixhobo sokufumana inzuzo, njenge-gallium arsenide (GaAs).
Iimpawu eziphambili ze-laser gain medium ziquka:
Ulwakhiwo lwenqanaba lamandla: Iiathom okanye iimolekyuli ezikwindawo yokufumana amandla kufuneka zibe nesakhiwo senqanaba lamandla esifanelekileyo ukuze kufikelelwe ekujikeni kwenani labantu phantsi kokukhuthazwa kwamandla angaphandle. Oku kuthetha ukuba umahluko wamandla phakathi kwamanqanaba aphezulu naphantsi wamandla kufuneka ulingane namandla e-photon obubanzi bobude bexesha elithile.

Iimpawu zotshintsho: Iiathom okanye iimolekyuli ezikwimeko ezichulumancisayo kufuneka zibe neempawu zotshintsho ezizinzileyo ukuze zikhuphe iiphoton ezihambelanayo ngexesha lemitha echulumancisayo. Oku kufuna ukuba i-gain medium ibe nokusebenza kakuhle kwe-quantum kunye nokulahleka okuphantsi.
Uzinzo lobushushu kunye namandla oomatshini: Kwiindlela ezisebenzayo, i-gain medium kufuneka imelane nokukhanya kwepompo enamandla aphezulu kunye nemveliso yelaser, ngoko ke kufuneka ibe nozinzo oluhle lobushushu kunye namandla oomatshini.
Umgangatho we-Optical: Umgangatho we-optical we-gain medium ubalulekile ekusebenzeni kwe-laser. Kufuneka ibe nokukhanya okuphezulu kunye nokulahleka okuncinci kokusasazeka ukuqinisekisa umgangatho kunye nozinzo lwe-laser beam. Ukukhetha i-laser gain medium kuxhomekeke kwiimfuno zokusetyenziswa kwe-laser.ileza, ubude bomda obusebenzayo, amandla okukhupha kunye nezinye izinto. Ngokuphucula izixhobo kunye nolwakhiwo lwe-gain medium, ukusebenza kunye nokusebenza kakuhle kwe-laser kunokuphuculwa ngakumbi.
