Liteko tse ngata tsa LPT-11 ho Semiconductor Laser

Tlhaloso

Laser ka kakaretso e na le likarolo tse tharo
(1) Laser sebetsa seaplane
Ho hlahisa laser ho tlameha ho khetha mokhoa o nepahetseng oa ho sebetsa, oo e ka bang khase, metsi, tiileng kapa semiconductor.Ka mofuta ona oa mahareng, ho kheloha ha palo ea likaroloana ho ka phethahala, e leng boemo bo hlokahalang ho fumana laser.Ho hlakile hore ho ba teng ha boemo ba matla a metastable ho molemo haholo ho elelloa ho kheloha ha palo.Hajoale, ho na le mefuta e ka bang 1000 ea mecha ea phatlalatso e sebetsang, e ka hlahisang mefuta e mengata ea maqhubu a laser ho tloha ho VUV ho ea ho infrared.
(2) Mohloli oa khothatso
E le ho etsa hore ho kheloha ha palo ea likaroloana ho hlahe sebakeng se sebetsang, hoa hlokahala ho sebelisa mekhoa e itseng ea ho thabisa tsamaiso ea athomo ho eketsa palo ea likaroloana tse ka holimo.Ka kakaretso, ho tsoa ha khase ho ka sebelisoa ho hlasimolla liathomo tsa dielectric ka lielektrone tse nang le matla a kinetic, a bitsoang excitation ea motlakase;mohloli o khanyang oa pulse o ka boela oa sebelisoa ho irradiate medium work, e bitsoang optical excitation;ho tsosoa ha mocheso, ho tsosoa ha lik'hemik'hale, joalo-joalo Mekhoa e fapaneng ea ho hlasimolla e bonoa e le pompo kapa pompo.E le ho fumana tlhahiso ea laser ka ho tsoelang pele, ho hlokahala hore u pompe ka ho tsoelang pele ho boloka palo ea likaroloana tse ka holimo ho feta tse ka tlaase.
(3) Mokotla o monyebe
Ka thepa e loketseng ea ho sebetsa le mohloli oa ho hlasimolla, ho kheloha ha palo ea likaroloana ho ka phethahala, empa matla a mahlaseli a tsositsoeng a fokola haholo, kahoo a ke ke a sebelisoa ka mokhoa o sebetsang.Kahoo batho ba nahana ho sebelisa resonator ea optical ho holisa.Seo ho thoeng ke optical resonator ha e le hantle ke liipone tse peli tse nang le ponahalo e phahameng e kentsoeng sefahleho le sefahleho lipheletsong tse peli tsa laser.E 'ngoe e batla e le ponahatso e felletseng, e' ngoe e bonts'oa haholo ebile e fetisoa hanyane, e le hore laser e ka hlahisoa ka seiponeng.Leseli le khantšitsoeng morao sebakeng se sebetsang le tsoela pele ho hlahisa mahlaseli a macha a hlasimollang, 'me leseli lea phahamisoa.Ka hona, leseli le pota-pota ka morao le pele ka har'a resonator, e leng se etsang hore ho be le karabelo ea ketane, e phahamisitsoeng joaloka avalanche, e hlahisang tlhahiso e matla ea laser ho tloha pheletsong e 'ngoe ea seipone se bontšang karolo e itseng.
