Izindaba - Kuyini ukumpompelwa kwe-optical e-laser?

Bhalisela imidiya yethu yezenhlalo yokuthumela okusheshayo

Emqoka wayo, ukupompa kwe-laser kuyinqubo yokunikeza amandla aphakathi ukuze kufinyelelwe isimo lapho kungakhipha khona ukukhanya kwe-laser. Lokhu kuvame ukwenziwa ngokujova ukukhanya noma ugesi wamanje kuma-medium, ama-athomu alo futhi okuholela ekuphumeni kokukhanya okubumbene. Le nqubo esekelwe ivele kakhulu kusukela kwavela ama-lasers okuqala maphakathi nekhulu lama-20.

Ngenkathi kuvame ukufanekisela izilinganiso zezilinganiso, ukupompa kwe-laser kuyinqubo yokusebenza kwe-quantum. Kubandakanya ukusebenzisana okuyinkimbinkimbi phakathi kwezithombe kanye nokwakheka kwe-athomu noma nge-molecular of inzuzo medium. Amamodeli athuthukile abheka izinto ezifana neRabi Oscillations, enikeza ukuqonda okwengeziwe kwalokhu kuhlangana.

I-Laser Pumpeling inqubo lapho amandla khona, imvamisa esesimweni sokukhanya noma kagesi samanje, ihlinzekwa ngokuthola okuphakathi kwe-laser ukuphakamisa ama-athomu awo noma ama-molecule afinyelela ema-athomu aphezulu. Lokhu kudluliswa kwamandla kubalulekile ekufezekiseni i-Inversion yabantu, isimo lapho izinhlayiya eziningi zijabule kakhulu kunombuso wamandla aphansi, okwenza amandla amuncu ukukhulisa ukukhanya nge-Emission evuselelayo. Le nqubo ifaka phakathi ukusebenzisana okuyinkimbinkimbi, okuvame ukufanekisa ngezilinganiso zezilinganiso noma izinhlaka ze-quantum mechanical. Izici ezibalulekile zifaka ukukhetha komthombo wepompo (njenge-laser diodes noma amalambu okukhipha), i-pump ge geometry (uhlangothi noma ukuphetha), nokusebenza kwekhwalithi yepompo (i-polarization) ukufanisa izidingo ezithile ze-inzuzo medium. I-Laser Pumpeling iyisisekelo ezinhlotsheni ezahlukahlukene ze-laser, kufaka phakathi ama-lood-state, ama-semiconductor, kanye namagesi egesi, futhi kubalulekile ekusebenzeni kahle kwe-laser nokusebenzayo.

Izinhlobonhlobo zama-lasers aphephe kakhulu

1. Ama-Lasers aqinile wombuso onama-insulators we-doped

· Ukubuka konke:Lawa ama-lasers asebenzisa i-liment ephakathi kukagesi ephakathi futhi ancike ekumpompelweni kwe-optical ukunika amandla i-ions-esebenzayo. Isibonelo esivamile yiNeodmium e-Yag Lasers.

·Ucwaningo lwakamuva:Ucwaningo ngo-Antipov et al. Ixoxa nge-SOLICAL-State Eseduze ne-Laser ye-Spin-Exchange Optical Pump. Lolu cwaningo luqokomisa intuthuko kubuchwepheshe be-laser bost-state laser, ikakhulukazi esibonelweni esiseduze se-infrared, esibaluleke kakhulu kwizicelo ezinjengokucabanga kwezokwelapha kanye nokuxhumana ngocingo.

Ukufunda okwengeziwe:Isimo esiqinile se-eduzane ne-laser ye-spin-spin-ukushintshaniswa kwe-optical pump

2. I-Semiconductor Lasers

·Imininingwane Ejwayelekile: Ngokuvamile i-Elect ngogesi ephephe kakhulu, ama-semiconductor ama-lasers nawo angazuza ngokupompa okubonakalayo, ikakhulukazi kuzinhlelo zokusebenza ezidinga ukugqama okuphezulu, okufana nendawo evulekile yangaphandle yokukhava kwama-lasers (ama-vecsels).

·Ukuthuthuka kwakamuva: U. Umsebenzi kaKeller kuma-optical frequency affectuency avela ku-Ultrafast ama-Loji-State-State-State Lasers ahlinzeka ngokuqonda esizukulwaneni sokuzinza ama-diode-state ama-lases Le ntuthuko ibalulekile kwizicelo ku-Optical Frequency Metrology.

Ukufunda okwengeziwe:I-Optical Frequency ihlangana kusuka ku-Ultrafast swoor-State-State Lasers kanye ne-Semiconductor

3. Ama-Lasers wegesi

·Ukumpompeni kwe-Optical kuma-Lasers egesi: Izinhlobo ezithile zama-lasers egesi, njenge-Alkali Vapor Lasers, Sebenzisa ukupompa okubonakalayo. Lawa ama-lasers ajwayele ukusetshenziswa kuzinhlelo zokusebenza ezidinga imithombo enokukhanya ehambisanayo enezakhiwo ezithile.

Imithombo yokupompa okubonakalayo

Khipha izibani: Okuvamile kuma-lasers aphepheni amakhambo, kusetshenziselwa izibani zamalambu aphezulu kanye ne-spectrum ebanzi. Ya mandryko et al. Uthuthukise imodeli yamandla yokukhishwa kwe-Impulse ARC ukukhiqizwa kweMedia Optical Pumps Pumpering XENON LAMANDS amalambu wombuso oqinile. Le modeli isiza ukwandisa ukusebenza kwamalambu okupompo wokuphonsa, okubalulekile ekusebenzeni kwe-laser okusebenzayo.

I-Laser Diodes:Isetshenziswa kuma-lasers we-diode, ama-laser diodees anikela ngezinzuzo njengokusebenza kahle okuphezulu, usayizi ohlangene, kanye nekhono lokuhlelwa kahle.

Ukufunda okwengeziwe:Iyini i-laser diode?

Izibani ze-Flash: Amalambu we-Flash anamandla, imithombo ekhanyayo ebanzi evame ukusetshenziswa ukupompa ama-laser-state lasers, njenge-ruby noma i-ND: ama-laser we-yag. Bahlinzeka ngokuqhuma okuphezulu kokukhanya okujabulisa i-laser medium.

Izibani ze-arc: Kuyafana namalambu we-flash kepha yakhelwe ukusebenza okuqhubekayo, izibani ze-arc zinikeza umthombo oqinile wokukhanya okukhulu. Zisetshenziswa kuzinhlelo zokusebenza lapho kusebenza khona ukusebenza kwe-laser (CW) okuqhubekayo (CW).

Ama-LEDs (ukukhanya okukhanyisa ama-diode): Ngenkathi kungejwayelekile njenge-Laser Diodes, ama-LED angasetshenziselwa ukupompa okubonakalayo kuzicelo ezithile ezinamandla aphansi. Banenzuzo ngenxa yempilo yabo ende, izindleko eziphansi, nokutholakala kuma-wavelength ahlukahlukene.

Ukukhanya kwelanga: Kwamanye amasethi wokuhlola, ukukhanya kwelanga okuhlanganisiwe kusetshenziswe njengomthombo wepampu wama-lasers elanga. Le ndlela inamahlaya ama-solar amandla, okwenza kube ngumthombo ovuselelekayo futhi ongabizi, yize kungalawuleki futhi kunzima kakhulu uma kuqhathaniswa nemithombo yokukhanya.

I-Fibre-Coupled Laser Diades: Lezi yi-laser diodes ehambisana nemicu ye-optical, eletha ukukhanya kwepompo ngempumelelo ku-laser medium. Le ndlela iwusizo ikakhulukazi kuma-lasers e-fiber kanye nasezimweni lapho ukulethwa okunembile kokukhanya kwepompo kubalulekile.

Amanye ama-lasers: Kwesinye isikhathi, i-laser eyodwa isetshenziselwa ukupompa enye. Isibonelo, i-ND yemvamisa evamile: I-Lag Laser ingahle isetshenziselwe ukupompa i-Waser yedayi. Le ndlela isetshenziswa kaningi lapho kudingeka ama-wavelength athile kwinqubo yokupompa engatholakalanga kalula ngemithombo evamile yokukhanya.

I-Diode-Pumped SOOL-State Laser

Umthombo Wokuqala Wendla: Inqubo iqala nge-diode laser, esebenza njengomthombo wamaphampu. Ama-Diode Lasers akhethelwe ukusebenza kwawo, usayizi weCompact, kanye nekhono lokukhipha ukukhanya kuma-wavelength athile.

Ukukhanya kwepompo:I-Diode Laser ikhipha ukukhanya okudonswa yi-SOLIL-State Get Filed. I-wavelength ye-diode laser yenzelwe ukufanisa izici zokutholwa kwe-inzuzo medium.

Isimo esiqinileThola okuphakathi

Okubonakalayo:I-Get Filed ku-DPSS Lasers imvamisa iyinto eqinile yombuso ofana ne-ND: i-yag (neodymium-doped yttrium aluminium garonet), noma i-yb (i-yedterbium-doped yttrium aluminium garnet.

DOPING:Lezi zinto zokwenziwa zithathwa ngama-ion are-Earth ion (njenge-ND noma i-yb), okuyi-laser ion esebenzayo.

Ukumuncwa kwamandla nokuvusa:Lapho ukukhanya kwepompo kusuka ku-diode laser kufaka inzuzo ephakathi nendawo, i-ions are-Earth ion insiza la mandla futhi ujabule emazweni aphezulu wamandla.

Ukuphambuka kwabantu

Ukuthola Ukuphambuka Kwenani Labantu:Isihluthulelo se-laser action sifinyelela ekuphambukeni kwabantu ekutholeni okuphakathi. Lokhu kusho ukuthi amanye ama-ion asesimweni esijabulisayo kunasesimweni somhlabathi.

Ukuphuma okuvuselelayo:Uma isingeniso sabantu sitholakala, ukwethulwa kwe-Photon okuhambelana nomehluko wamandla phakathi kwezifunda ezijabulisayo nezibuyayo kungavusa ama-ion ajabule ukubuyela esimweni somhlaba.

I-Optical resonator

Izibuko: Ukuthola inzuzo kufakwa ngaphakathi komthengisi we-optical

Impendulo kanye nokukhuliswa: esinye sezibuko sibonisa kakhulu, kanti okunye kukhombisa ngokwengxenye. Ama-Photon agxumela emuva naphambili phakathi kwalezi zibuko, okuvuselelwa okuthe xaxa nokukhuthaza ukukhanya.

Ukuphuma kwe-laser

Ukukhanya okubumbene

Okukhipha: Isibuko esibonisa ngokwengxenye sivumela okunye kwalokhu kukhanya ukuthi kudlule, kwakha ugongolo lwe-laser oluphuma i-DPSS laser.
