Bhalisela imidiya yethu yezenhlalo yokuthumela okusheshayo

Ama-Lasers, itshe lobuchwepheshe besimanje, athakazelisa njengoba eyinkimbinkimbi. Ezinhlizweni zabo kulele ukuvumelanisa izingxenye ezisebenza ngobunye ukukhiqiza ukukhanya okubumbene, okukhulisiwe. Le bhulogi ingena kwizinkampani zalezi zingxenye, ezisekelwa yimigomo yesayensi kanye nezibalo, ukuhlinzeka ngokuqonda okujulile kobuchwepheshe be-laser.

Ukuqonda okuthuthukile kuzakhi zohlelo lwe-laser: umbono wezobuchwepheshe ochwepheshe

Ingxenye	Sebenza	Izibonelo
Thola okuphakathi	Ukuthola okuphakathi yinto esetshenziselwa i-laser esetshenziselwa ukukhalisa ukukhanya. Inika amandla okuphola okukhanyayo ngenqubo yokuphambuka kwabantu kanye nokuphuma okuvuselelayo. Ukukhetha kwe-Gain Medium kunquma izici zemisebe ye-laser.	Ama-lasers aqinile wombuso: isib.Ama-lasers egesi: isib, ama-lasers e-CO2, asetshenziselwa ukusika kanye nokushiswa.Ama-Semiconductor Lasers:I-Eg, Laser Diodes, esetshenziswa ekuxhumaneni kwe-Fiber Optics kanye nezikhombisi ze-laser.
Umthombo wokupompa	Umthombo wePumpering unikeza amandla aphakathi nendawo ukuze uzuze inani labantu (umthombo wamandla wokuphambuka kwabantu), enika amandla ukusebenza kwe-laser.	Ukupompa Optical: Usebenzisa imithombo ekhanyayo enamandla njenge-flashlamps ukupompa ama-lasers aqinile.Ukupompa kagesi: Igesi ethokozisayo egesi e-Lasers yegesi ngokusebenzisa kagesi kwamanje.I-semiconductor yokupompa: Usebenzisa ama-laser diodes ukupompa okuphakathi kwe-laser medial.
I-Optical cavity	I-cavity ye-optical, enezibuko ezimbili, ikhombisa ukukhanya ukukhulisa ubude bendlela yokukhanya ku-inzuzo medium, ngaleyo ndlela kuthuthukiswe ukukhuliswa okukhanyayo. Inikeza indlela yokuphendula ye-Laser Amplification, ukhetha izici ezibukhali nezendawo zokukhanya.	I-Planethi-Planethi Cavity: Kusetshenziswe ocwaningweni lwelebhu, isakhiwo esilula.Plalar-concave cavity: Okujwayelekile kuma-lasers wezimboni, kunikeza imishayo esezingeni eliphakeme.

Inzuzo ephakathi: i-nexus of quantum mechanics nobunjiniyela bokubona

Ama-Quantum Dynamics ekutholeni okuphakathi

I-Get Filed yilapho inqubo eyisisekelo yokukhishwa okulula kwenzeka, into egxile kakhulu kuma-quantum mechanics. Ukuxhumana phakathi kwezindawo zamandla nezinhlayiya ngaphakathi kwe-Medium kulawulwa yimigomo yokukhuthaza ukuphuma nokuphambukiswa kwabantu. Ubudlelwano obubucayi phakathi kokukhanya okukhanyayo (i), ubukhulu bokuqala (i0), isigaba sesipharia (Σ21) (Σkelele Ukuthola i-inversion yabantu, lapho i-N2> N1, ibalulekile ekwakhiweni futhi iyitshe le-Laser physics [1].

Ama-vs amathathu-izinga lama-vs amasilinganiso ezine

Emiklamweni ye-laser esebenzayo, amasistimu anezinga ezintathu nezinkane ajwayele ukuqashwa. Amasistimu aleveli amathathu, ngenkathi okulula, adinga amandla amaningi ukufezekisa ukungenelela kwabantu njengoba izinga le-laser eliphansi liyisimo somhlaba. Izindlela ezine-ezine, ngakolunye uhlangothi, zinikeza indlela esebenza kahle ekuphambukeni kwabantu ngenxa yokuwohloka okusheshayo okungaphezulu kwe-radiative kusuka ezingeni eliphakeme lamandla, kubenza bavame kakhulu kwizicelo zama-Laser zesimanje [2].

Is Ingilazi ye-Erbium-dopedUkuthola okuphakathi?

Yebo, ingilazi ye-erbium-doped empeleni iluhlobo lwe-Get Medium esetshenziswa ezinhlelweni ze-laser. Kulesi simo, "ukudonsa" kubhekisele kwinqubo yokwengeza inani elithile lama-eIon (er³⁺) engilazini. I-Erbium iyinto engavamile yomhlaba, lapho ifakwe kumgcini wengilazi, ingakhulisa kahle ukukhanya ngokuphuma okuvuselelwa, inqubo eyisisekelo ekusebenzeni kwe-laser.

Ingilazi ye-Erbium-doped iyamangaza ngokukhethekile ukusetshenziswa kwayo ku-fiber lasers kanye nama-amplifier fiber, ikakhulukazi embonini yezokuxhumana. Ilungele kahle lezi zinhlelo zokusebenza ngoba ilula ngokukhanyisa ama-wavelength cishe ngo-1550 nm, okuyi-wavelength yokhiye wokuxhumana kwe-fiber okuphezulu ngenxa yokulahleka kwayo okuphansi ngenxa yemicu evamile ye-silica.

Le khasiumphethoI-ions donsa i-pump light (imvamisa kusuka kuI-Laser Diode) futhi bajabule kakhulu emandleni aphakeme. Lapho bebuyela esimweni samandla aphansi, bakhipha ama-photon e-wavength ye-lasing, bafaka isandla kwinqubo ye-laser. Lokhu kwenza ingilazi ye-erbium-doped ibe yinzuzo esebenzayo futhi isetshenziswe kabanzi okuphakathi kwemiklamo ehlukahlukene ye-laser kanye ne-amplifier.

Izindlela zokuposela: amandla okushayela ngemuva kwama-lasers

Izindlela ezahlukahlukene zokuthola i-Inversion Yabantu

Ukukhethwa kwemishini yokupompa kubalulekile ekwakhiweni kwe-laser, kuthonya konke kusuka ekusebenzeni kahle ekuphumeni kwe-wavength. Ukumpompa okwe-Optical, kusetshenziswa imithombo yokukhanya yangaphandle efana nama-flashlamp noma amanye ama-lasers, kuvamile kuma-lasers aqinile nodayi. Izindlela zokukhishwa kukagesi zivame ukuqashwa kuma-lasers egesi, ngenkathi ama-semiconductor lasers avame ukusebenzisa umjovo we-elektroni. Ukusebenza kahle kwalezi zinqubo zokupompa, ikakhulukazi kuma-diode-pumped-swolive-slow-State Lasers, kube ukugxila okukhulu ngocwaningo lwakamuva, okuhlinzeka ngokusebenza okuphezulu nokuhlangana [3].

Ukucatshangelwa Kwezobuchwepheshe Ekusebenzeni Kokupompa

Ukusebenza kahle kwenqubo yokupompa kuyisici esibucayi sokwakhiwa kwe-laser, okunomthelela ekusebenzeni okuphelele kanye nokufaneleka kwesicelo. E-lasers eqinile, okukhethiwe phakathi kwama-flashlamp kanye nama-laser diodes njengomthombo wephampu kungathinta kakhulu ukusebenza kahle kohlelo, umthwalo we-thermal, kanye nekhwalithi ye-beam. Ukuthuthukiswa kwamandla aphezulu, ama-laser diode aguqukayo aguqule amasistimu we-DPSS Laser, okwenza amandla ama-compact amaningi ama-compact futhi afanele [4].

I-Optical Cavity: Ubunjiniyela be-laser beam

I-Cavity Design: isenzo sokulinganisa se-physics kanye nobunjiniyela

I-optical cavity, noma i-resonator, akuyona nje ingxenye nje engenangqondo kodwa obambe iqhaza osebenzayo ekubumbeni ugongolo lwe-laser. Idizayini ye-cavity, kufaka phakathi i-curvature kanye nokuqondanisa kwezibuko, idlala indima ebalulekile ekunqumeni ukuqina, ukwakheka kwemodi, nokukhishwa kwe-laser. I-cavity kumele yakhelwe ukuthuthukisa inzuzo ye-optical ngenkathi inciphisa ukulahleka, inselelo ehlanganisa ubunjiniyela be-optical nge-wave optics5.

Izimo ze-Oscillation nokukhethwa kweModi

Ukuze i-laser oscillation yenzeke, inzuzo enikezwe okuphakathi kumele idlule ukulahleka ngaphakathi komgodi. Lesi simo, sihambisana nesidingo sama-superposition ahambisanayo we-wave, abhale ukuthi yizindlela ezithile ezithile ezinde ezisekelwa. Isikhala semodi kanye nesakhiwo semodi ephelele sithonywa ubude benyama be-cavity kanye nenkomba evulekayo ye-inzuzo medium [6].

Ukugcina

Idizayini kanye nokusebenza kwezinhlelo ze-laser kufaka phakathi isibukeli esibanzi se-physics kanye nemigomo yobunjiniyela. Kusukela kuma-hantum mechanics alawula ukuzuza okuphakathi nobunjiniyela obuyinkimbinkimbi be-aptical cavity, ingxenye ngayinye yesistimu ye-laser idlala indima ebalulekile ekusebenzeni kwayo okuphelele. Le ndatshana ihlinzeke kancane ezweni eliyinkimbinkimbi yeLaser Technology, enikeza ukuqonda okuvumelana nokuqonda okuthuthukile kochwepheshe be-profesa kanye nonjiniyela be-optical endle.
