Izimiso nezinhlobo ze-laser

Izimiso nezinhlobo zei-laser
Yini i-laser?
I-laser (ukukhuliswa okukhanyayo okuvuselelwa okwenziwa kabusha kwemisebe); Ukuze uthole umbono ongcono, bheka isithombe esingezansi:

I-athomu endaweni ephakeme yamandla iguqukela ngokuzenzakalelayo ezingeni eliphansi lamandla futhi likhipha i-Photon, inqubo ebizwa ngokuthi yimisebe ye-pontation.
Okudumile kungaqondakala njenge: ibhola emhlabathini liyisikhundla salo esifanele kunazo zonke, lapho ibhola lidonswa emoyeni ngamandla angaphandle (abizwa ngokuthi amandla okumpompa anyamalala, bese kubangela amandla athile. Uma ibhola liyi-athomu elithile, khona-ke i-athomu ikhipha i-Photon ye-wavelength ethile ngesikhathi soguquko.

Ukuhlukaniswa kwama-lasers
Abantu baye baqonda kahle umgomo wesizukulwane se-laser, baqala ukuthuthukisa izinhlobo ezahlukene ze-laser, uma ngokwezinto ezisebenzayo ze-laser ukuze zihlukanise, zingahlukaniswa nge-laser yegesi, i-sexenductor laser, njll.
1, Ukuhlukaniswa Kwe-Laser Laser: I-Atom, Molecule, Ion;
Into esebenzayo yegesi ye-laser yigesi noma i-metal vapor, ebonakala ngobubanzi obubanzi be-waver. Okuvame kakhulu yi-CO2 laser, lapho i-CO2 isetshenziswa njengento esebenzayo ukukhiqiza i-laser ye-infrared of 10.6um ngokuvuselelwa kokukhishwa kukagesi.
Ngoba into esebenza i-laser yegesi igesi, ukwakheka okuphelele kwe-laser kukhulu kakhulu, futhi i-avexthth yegesi yegesi yinde kakhulu, ukusebenza kwezinto ezibonakalayo akukuhle. Ngakho-ke, ama-lasers wegesi asuswa maduze emakethe, futhi asetshenziswa kuphela ezindaweni ezithile ezithile, njengokumaka kwe-laser kwezingxenye ezithile zepulasitiki.
2, I-LASER eqinileUkuhlukaniswa: URuby, ND: I-Yag, njll;
Ukusebenza okusebenzayo kwe-Laser yombuso oqinile yi-ruby, ingilazi ye-neodymium, i-yttrium aluminium garnet, njll.
I-Laser eqinile ye-Solid-State yakhiwa yinto esebenzayo, uhlelo lokuphonsa, umshuwaleki nohlelo olupholile nokuhlunga.Isikwele esimnyama phakathi kwesithombe esisengezansi, okubukeka njenge-crystal ekhanyayo ekhanyayo, kuqukethe ikristalu esobala edabula ngezinsimbi zomhlaba ezingavamile. Ukwakheka okukhethekile kwe-athomu lomhlaba elingavamile elenziwa yi-athomu ye-athomu ye-rate yabantu lapho kukhanyiswa umthombo wokukhanya (uma kutholakale ukuthi amabhola amaningi e-laser. izibuko (ilensi efanele). Lapho okukhipha ama-laser bese kuthi lapho kuvela khona umklamo othile obonakalayo, ukwakheka kwamandla we-laser.

3, I-Semiconductor Laser
Uma kukhulunywa ngama-Semiconductor Lasers, kungaqondwa nje njenge-PhotoDiode, kukhona umhlangano we-PN e-Diode, futhi lapho kufakwa khona okukhona okukhona, ukuguquka kwe-semicenductor kwakhiwa ukukhipha ama-photons, okuholela e-laser. Lapho amandla e-laser ekhishwe yi-semiconductor incane, idivaysi ephansi yamandla emi-semiconductor ingasetshenziswa njengomthombo wepompo (umthombo wokuthokozisa) wei-fiber laser, ngakho-ke kwakhiwa i-laser ye-fiber. Uma amandla e-semiconductor laser esekwe ngokwengeziwe kuze kube yilapho kungavela ngokuqondile ukucubungula izinto zokwakha, kuba yi-tecconductor laser. Njengamanje, ama-leconductor aqondile emakethe afinyelele ezingeni le-10,000-watt.

Ngaphezu kwalokhu okungenhla kwama-lasers ambalwa, abantu basungule futhi ama-lasers awuketshezi, owaziwa nangokuthi ama-lasers amafutha. Ama-liquid ama-lasers ayinkimbinkimbi ngokwengeziwe ngento yevolumu neyasebenza kunama-solids futhi akuvamile ukusetshenziswa.
