Izici ezibalulekile ze-laser gain medium

Yiziphi izici ezibalulekile ze-laser gain media?

I-Laser gain medium, eyaziwa nangokuthi i-laser working substance, ibhekisela ohlelweni lwezinto ezisetshenziswa ukufeza ukuguqulwa kwenani lezinhlayiya futhi ikhiqize imisebe evuselelwe ukuze kufezwe ukukhuliswa kokukhanya. Yingxenye eyinhloko ye-laser, ephethe inani elikhulu lama-athomu noma ama-molecule, lawa ma-athomu noma ama-molecule ngaphansi kokukhuthazwa kwamandla angaphandle, angashintshela esimweni sokuvuselelwa, futhi ngokusebenzisa imisebe evuselelwe ikhiphe ama-photon, ngaleyo ndlela kwakhaukukhanya kwe-laser. I-laser gain medium ingaba yinto eqinile, ewuketshezi, yegesi noma ye-semiconductor.
Kuma-laser aqinile, i-gain media esetshenziswa kakhulu yi-crystals exutshwe nama-ion omhlaba angavamile noma ama-ion ensimbi yokuguquguquka, njenge-Nd:YAG crystals, Nd:YVO4 crystals, njll. Kuma-laser aketshezi, amadayi e-organic avame ukusetshenziswa njenge-gain media. Ama-gas lasers asebenzisa i-gain media njenge-gain medium, njenge-carbon dioxide gas kuma-laser e-carbon dioxide, kanye ne-helium ne-neon gas kuma-laser e-helium-neon.Ama-laser e-semiconductorsebenzisa izinto ze-semiconductor njenge-gain medium, njenge-gallium arsenide (GaAs).
Izici ezibalulekile ze-laser gain medium zifaka:
Isakhiwo sezinga lamandla: Ama-athomu noma ama-molecule endaweni yokuzuza kudingeka abe nesakhiwo sezinga lamandla esifanele ukuze kufezwe ukuguquka kwenani labantu ngaphansi kokukhuthazwa kwamandla angaphandle. Lokhu ngokuvamile kusho ukuthi umehluko wamandla phakathi kwamazinga aphezulu naphansi wamandla udinga ukufanisa amandla e-photon we-wavelength ethile.

Izakhiwo zokuguquka: Ama-athomu noma ama-molecule ezimweni ezijabulisayo kudingeka abe nezakhiwo zokuguquka ezizinzile ukuze akhiphe ama-photon ahambisanayo ngesikhathi sokukhishwa kwemisebe ejabulisayo. Lokhu kudinga i-gain medium ukuze ibe nokusebenza kahle kwe-quantum ephezulu kanye nokulahlekelwa okuphansi.
Ukuqina kokushisa kanye namandla omshini: Ezisetshenzisweni ezisebenzayo, i-gain medium idinga ukumelana nokukhanya kwephampu enamandla aphezulu kanye nokukhishwa kwe-laser, ngakho-ke idinga ukuba nokuqina okuhle kokushisa kanye namandla omshini.
Ikhwalithi yokubona: Ikhwalithi yokubona ye-gain medium ibalulekile ekusebenzeni kwe-laser. Kudingeka ibe nokudlulisa ukukhanya okuphezulu kanye nokulahlekelwa okuphansi kokusabalala ukuqinisekisa ikhwalithi kanye nokuqina komsebe we-laser. Ukukhetha i-laser gain medium kuncike ezidingweni zokusetshenziswa kwe-i-laser, ubude besikhathi obusebenzayo, amandla okukhipha kanye nezinye izici. Ngokwenza ngcono izinto kanye nesakhiwo se-gain medium, ukusebenza kanye nokusebenza kahle kwe-laser kungathuthukiswa kakhulu.
