Isifinyezo samandla aphezului-laser ye-semiconductorintuthuko ingxenye yesibili
I-laser yefayibha.
Ama-laser e-fiber ahlinzeka ngendlela engabizi kakhulu yokuguqula ukukhanya kwama-laser e-semiconductor anamandla aphezulu. Nakuba ama-optical e-multiplexing wavelength angaguqula ama-laser e-semiconductor akhanya kancane abe akhanya kakhulu, lokhu kuza ngezindleko zobubanzi obukhulayo be-spectral kanye nobunzima be-photomechanical. Ama-laser e-fiber abonakale esebenza kahle kakhulu ekuguqulweni kokukhanya.
Imicu eboshwe kabili eyethulwa ngawo-1990, isebenzisa umongo wemodi eyodwa ozungezwe ukumbozwa kwemodi eminingi, ingangenisa ngempumelelo ama-laser e-multimode semiconductor pump anamandla aphezulu, angabizi kakhulu ku-fiber, idale indlela engabizi kakhulu yokuguqula ama-laser e-semiconductor anamandla aphezulu abe yimithombo yokukhanya ekhanyayo. Kuma-fiber e-ytterbium-doped (Yb), iphampu ivusa ibhendi yokumunca ebanzi ephakathi ku-915nm, noma ibhendi yokumunca encane eduze kuka-976nm. Njengoba ubude be-wavelength yokumpompa busondela kubude be-wavelength obuhlala isikhathi eside be-fiber laser, lokho okubizwa ngokuthi i-quantum deficit kuyancishiswa, kukhulisa ukusebenza kahle futhi kunciphise inani lokushisa okudinga ukuhlakazwa.
Ama-laser e-fiberkanye nama-laser aqinile adonswa yi-diode ancike ekwandeni kokukhanya kwe-i-laser ye-diodeNgokuvamile, njengoba ukukhanya kwama-laser e-diode kuqhubeka nokuthuthuka, amandla ama-laser awampompa nawo ayanda. Ukuthuthukiswa kokukhanya kwama-laser e-semiconductor kuvame ukukhuthaza ukuguqulwa kokukhanya okusebenzayo kakhudlwana.
Njengoba silindele, ukukhanya kwendawo kanye ne-spectral kuzodingeka ezinhlelweni zesikhathi esizayo ezizovumela ukupompa kwe-quantum deficit okuphansi ukuze kutholakale izici zokumunca okuncane kuma-laser aqinile, kanye nezinhlelo zokusebenzisa kabusha ubude be-wavelength obukhulu bezinhlelo zokusebenza ze-laser ye-semiconductor eqondile.

Imakethe kanye nesicelo
Intuthuko kuma-laser e-semiconductor anamandla amakhulu yenze izinhlelo zokusebenza eziningi ezibalulekile zaba nokwenzeka. Njengoba izindleko nge-watt yokukhanya ngayinye yama-laser e-semiconductor anamandla aphezulu zincishisiwe kakhulu, la ma-laser athatha indawo yobuchwepheshe obudala futhi avumela izigaba zemikhiqizo emisha.
Njengoba izindleko kanye nokusebenza kuthuthuka ngokuphindwe kayishumi njalo eminyakeni eyishumi, ama-laser e-semiconductor anamandla amakhulu aphazamise imakethe ngezindlela ezingalindelekile. Nakuba kunzima ukubikezela ukusetshenziswa kwesikhathi esizayo ngokunemba, kuyafundisa futhi ukubheka emuva eminyakeni engamashumi amathathu edlule ukuze ucabange ngamathuba eshumi leminyaka elizayo (bheka uMfanekiso 2).
Ngesikhathi uHall ebonisa ama-laser e-semiconductor eminyakeni engaphezu kwengu-50 eyedlule, wethula inguquko kwezobuchwepheshe. NjengoMthetho kaMoore, akekho owayengabikezela impumelelo ekhazimulayo yama-laser e-semiconductor anamandla amakhulu alandela ngezinto ezintsha ezahlukahlukene.
Ikusasa lama-laser e-semiconductor
Ayikho imithetho eyisisekelo yefiziksi elawula lokhu kuthuthukiswa, kodwa intuthuko eqhubekayo kwezobuchwepheshe cishe izoqhubeka nokuthuthukisa lokhu kuthuthukiswa okukhulu. Ama-laser e-semiconductor azoqhubeka nokufaka esikhundleni sobuchwepheshe bendabuko futhi azoshintsha indlela izinto ezenziwa ngayo. Okubaluleke kakhulu ekukhuleni komnotho, ama-laser e-semiconductor anamandla amakhulu azoshintsha nalokho okungenziwa.
