Iimpawu eziphambili ze-laser gain medium

Ziziphi iimpawu eziphambili ze-laser gain media?

I-Laser gain medium, ekwabizwa ngokuba yi-laser working substance, ibhekisa kwinkqubo yezinto esetyenziswayo ukufezekisa ukuguqulwa kwamasuntswana abahlali kunye nokuvelisa imitha evuselelayo ukufezekisa ukukhulisa ukukhanya. Yeyona nxalenye ingundoqo yelaser, ethwele inani elikhulu leathom okanye iimolekyuli, ezi athom okanye iimolekyuli eziphantsi kochulumanco lwamandla angaphandle, zinokutshintshela kwimeko echulumancisayo, kwaye ngemitha yemincili ekhutshwe iifotoni, ngaloo ndlela zenzaukukhanya laser. I-laser gain medium ingaba yinto eqinileyo, engamanzi, igesi okanye i-semiconductor.
Kwi-laser-state lasers, imithombo yeendaba exhaphakileyo esetyenziswa ngokuqhelekileyo i-crystals doped kunye ne-ion zomhlaba ezinqabileyo okanye ii-ion zetsimbi zenguqu, ezifana ne-Nd: YAG crystals, Nd: YVO4 crystals, njl. Kwi-laser ye-liquid, idayi ye-organic isetyenziswa rhoqo njengemithombo yeendaba. Iilaser zerhasi zisebenzisa irhasi njengendawo yokuzuza, efana negesi yekharbhon diokside kwiilaser zecarbon dioxide, kunye nehelium kunye negesi yeneon kwiilaser zehelium-neon.Ii-laser ze-semiconductorsebenzisa izixhobo ze-semiconductor njengendlela yokuzuza, njenge-gallium arsenide (GaAs).
Iimpawu eziphambili ze-laser gain medium ziquka:
Ubume benqanaba lamandla: Ii-athomu okanye iiathomu ezikwinqanaba lokuzuza kufuneka zibe nesakhiwo esifanelekileyo somgangatho wamandla ukuze kuphunyezwe ukuguqulwa kwabantu phantsi kochulumanco lwamandla angaphandle. Oku ngokuqhelekileyo kuthetha ukuba umahluko wamandla phakathi kwamanqanaba aphezulu nangaphantsi kwamandla kufuneka utshatise amandla ephoton obude obuthile.

Iipropati zenguqu: Ii-athomu okanye iiathomu kwiindawo ezivuyayo kufuneka zibe neepropati ezizinzileyo zokutshintsha ukuze zikhulule iifotoni ezihambelanayo ngexesha lemitha eyonwabileyo. Oku kufuna i-medium yokufumana inzuzo ukuba ibe nokusebenza kakuhle komyinge kunye nelahleko ephantsi.
Uzinzo lwe-Thermal kunye namandla omatshini: Kwizicelo ezisebenzayo, ukufumana okuphakathi kufuna ukumelana nokukhanya kwempompo yamandla aphezulu kunye nokuphuma kwe-laser, ngoko ke kufuneka kube nokuzinza okuhle kwe-thermal kunye namandla omatshini.
Umgangatho we-Optical: Umgangatho we-optical we- gain medium ubaluleke kakhulu ekusebenzeni kwe-laser. Kufuneka ibe nokuhanjiswa kokukhanya okuphezulu kunye nelahleko ephantsi yokusabalalisa ukuqinisekisa umgangatho kunye nokuzinza kwe-laser beam. Ukukhethwa kwe-laser gain medium kuxhomekeke kwiimfuno zesicelo selaser, ubude bokusebenza, amandla emveliso kunye nezinye izinto. Ngokulungisa izinto kunye nesakhiwo se-medium gain, ukusebenza kunye nokusebenza kakuhle kwe-laser kunokuphuculwa ngakumbi.
