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 olusetshenziswayo ukuze kuzuzwe ukuguqulwa kwezinhlayiyana zabantu kanye nokukhiqiza imisebe evuselelwe ukuze kuzuzwe ukukhulisa ukukhanya. Iyingxenye eyinhloko ye-laser, ephethe inani elikhulu lama-athomu noma ama-molecule, lawa ma-athomu noma ama-molecule ngaphansi kokuvuswa kwamandla angaphandle, angadlulela esimweni senjabulo, futhi ngokusebenzisa ama-photon akhishwe ngemisebe ejabulile, ngaleyo ndlela akheukukhanya kwe-laser. I-laser gain medium ingaba into eqinile, enguketshezi, yegesi noma ye-semiconductor.
Kuma-lasers wesimo esiqinile, imidiya yenzuzo evame ukusetshenziswa amakristalu ahlanganiswe nama-ion asemhlabeni ayivelakancane noma ama-ion ensimbi eshintshayo, njengamakristalu e-Nd:YAG, Nd:YVO4 crystals, njll. Kuma-lasers awuketshezi, odayi bemvelo bavame ukusetshenziswa njengemithombo yezindaba. Amalaser egesi asebenzisa igesi njengendlela yokuzuza, efana negesi ye-carbon dioxide kumalaser e-carbon dioxide, kanye ne-helium negesi ye-neon kumalaser e-helium-neon.Ama-laser we-semiconductorsebenzisa izinto ze-semiconductor njengendlela yokuzuza, njenge-gallium arsenide (GaAs).
Izici ezibalulekile ze-laser gain medium zifaka:
Isakhiwo sezinga lamandla: Ama-athomu noma ama-athomu asendaweni yenzuzo adinga ukuba nesakhiwo sezinga lamandla esifanelekile ukuze kuzuzwe ukuhlehla kwesibalo sabantu ngaphansi kwesasasa lamandla angaphandle. Lokhu ngokuvamile kusho ukuthi umehluko wamandla phakathi kwamazinga wamandla aphezulu naphansi udinga ukufanisa amandla e-photon we-wavelength ethile.

Izakhiwo zoguquko: Ama-athomu noma ama-molecule asezindaweni ezijabulile adinga ukuba nezinto ezizinzile zoguquko ukuze akhiphe ama-photon ahlangene phakathi nemisebe ejabulile. Lokhu kudinga indlela yokuthola ukuthi ibe nokusebenza kahle kwe-quantum ephezulu kanye nokulahlekelwa okuphansi.
Ukuzinza kwe-thermal namandla okusebenza: Ezisetshenziswa ezingokoqobo, indawo yokuzuza idinga ukumelana nokukhanya kwepompo yamandla aphezulu kanye nokuphuma kwe-laser, ngakho-ke idinga ukuba nokuzinza okuhle kokushisayo namandla okusebenza.
Ikhwalithi yokubona: Ikhwalithi yokubona yendawo yokuthola ibalulekile ekusebenzeni kwe-laser. Idinga ukudluliswa kokukhanya okuphezulu kanye nokulahlekelwa okuhlakazeka okuphansi ukuze kuqinisekiswe ikhwalithi nokuzinza kwe-laser beam. Ukukhethwa kwe-laser gain medium kuncike kwizidingo zohlelo lokusebenzalaser, i-wavelength yokusebenza, amandla okukhiphayo nezinye izici. Ngokwenza kahle izinto kanye nokwakheka kwendlela yokuthola, ukusebenza nokusebenza kahle kwe-laser kungathuthukiswa ngokwengeziwe.
