Imigaqo kunye neentlobo zei-laser
Yintoni i-laser?
I-laser (i-ameright ekhanyayo ngokukhutshwa kwemitha); Ukufumana uluvo olungcono, jonga umfanekiso ongezantsi:

I-ATOTO kwinqanaba eliphezulu lamandla otshintsho lwenqanaba lamandla asezantsi kwaye likhupha i-photon, inkqubo ebizwa ngokuba yimitha eshukumisayo.
Ithandwa ingaqondwa njenge: Ibhola esemhlabeni yeyona ndawo ifanelekileyo, xa ibhola ityumkile emoyeni ngamandla angaphandle (ebizwa ngokuba yimpompo), ibhola iwela kumninzi wamandla. Ukuba ibhola yiatom ethile, emva koko i-atom ikhupha i-photon ye-wavechongth ekhethekileyo ngexesha lotshintsho.

Ukuhlelwa kwee-lars
Abantu bafundile umgaqo wesizukulwana aseleyo, baqala ukukhulisa iindlela ezahlukeneyo ze-laser, ukuba ngokwezinto zomsebenzi ze-laser zihlelele, zinokwahlulwa zangaber igesi, i-lemiconductor, njl .. ..
I-1, i-Laser yeGeraser yeGerar: Atom, Molecule, ion;
Into yokusebenza ye-laser yegesi yigesi okanye i-vapor yensimbi, ebonakaliswa yindawo ebanzi yemveliso yokuphuma kweler. Eyona ixhaphakileyo yi-CO2: apho i-CO2 isetyenziswa njengezinto ezisebenzayo ukuvelisa i-leser ye-10.6m ngenjongo yokukhutshelwa kombane.
Kuba into esebenzayo ye-laser yegesi yirhasi, isakhiwo se-laser sikhulu kakhulu, kwaye imveliso yamanzi i-laser yegesi inde kakhulu, ukusebenza kwezinto ezibonakalayo akulunganga. Ke ngoko, ii-igers zegesi zapheliswa kungekudala emarikeni, kwaye zisetyenziswa kuphela kwiindawo ezithile, ezinjengeSursermaki yezahlulo ezithile zeplastiki.
2, I-laser eqinileyoUkuhlelwa: I-Ruby, i-ND: YAG, njl njl.;
Izinto zokusebenza ze-State State i-Laser ye-ruby, i-neodimium ye-rubymium, yttrium ganunum gamet (ye-YTTRIUNG), njl njl.
I-Laser ye-State-State idityaniswe nento esebenzayo, inkqubo yokumpompa, i-remosotor kunye nenkqubo yokuphola kunye nokucoca i-crystal efihlakeleyo kwaye inee-crystal ezinemibala enqabileyo. Lulwakhiwo olukhethekileyo lwe-atom enqabileyo yentsimbi eyenza i-versic inversion xa inyibilikisiwe i-moya, kwaye emva koko i-leser ikhutshiwe xa i-leser ikhutshiwe, kwaye i-lens epheleleyo (i-lens eshiyekileyo) kunye nemveliso ebonakalayo izibuko (iilensi ezifanelekileyo). Xa kusenziwa igalelo i-laser kwaye emva koko uyilo oluthile lokukhanya, ukwenziwa kwamandla e-laser.

3, I-Semiconductor Laser
Xa kufikwa kwi-Semiconductor Lasers, inokuqondwa nje njenge-Photodiode, kukho i-PN Junction kwiDioode, kwaye xa kuvulwa i-PN kwi-Dioode, kwaye i-elektroniki enziwayo yokukhupha iifoto, ezikhokelela eLaser. Xa amandla e-laser ekhutshwe ngu-semicondcuctor mncinci, isixhobo se-semicondcuctor sinokusetyenziswa njengomthombo wempompo (umthombo othandekayo) weI-Fiber Laser, ke kusenziwa ke i-fiber lare. Ukuba amandla e-semicondcuctorter lase-semicondcuctor uqhubeke ukuya kuthi ga kwinqanaba lokuba kungaphuhliswa ngokuthe ngqo kwizixhobo, kuba sisimo se-semiconductor lamer. Okwangoku, i-Semicondorctor Lasers kwimarike ifikelele kwinqanaba le-10,000 lattt.

Ukongeza kwezi zinto zingasentla i-lars, abantu bakwavelise i-laars ye-flue, ekwabizwa ngokuba zii-inders zepetroli. Iindlela zokuhamba ezingamanzi zintsonkothileyo kwivolumu kunye nezinto ezisebenzayo kunezinyibilikisi kwaye azifane zisetyenziswe.
