Ukubuka konke kokuthuthukiswa kwe-laser semiconductor yamandla aphezulu ingxenye yesibili

Uhlolojikelele lwamandla aphezuluI-semiconductor laserukuthuthukiswa ingxenye yesibili

I-fiber laser.
Ama-laser we-fiber ahlinzeka ngendlela engabizi kakhulu yokuguqula ukugqama kwama-laser we-semiconductor enamandla amakhulu. Nakuba i-wavelength multiplexing optics ingaguqula amalaser we-semiconductor anokukhanya okuphansi abe akhanya kakhulu, lokhu kuza ngezindleko zokukhuphuka kobubanzi be-spectral nobunkimbinkimbi be-photomechanical. Ama-laser e-fiber afakazele ukuthi asebenza kahle kakhulu ekuguquleni ukukhanya.

Imicu egqoke kabili eyethulwe ngeminyaka yawo-1990s, isebenzisa umongo wemodi eyodwa ezungezwe i-multimode cladding, ingakwazi ukwethula ngempumelelo amandla aphezulu, amanani aphansi e-multimode semiconductor pump lasers ibe yifayibha, idale indlela yokonga kakhudlwana yokuguqula ama-laser anamandla amakhulu we-semiconductor. emithonjeni yokukhanya egqamile. Kumafayibha e-ytterbium-doped (Yb), iphampu ijabulisa ibhendi yokumunca ebanzi emaphakathi ku-915nm, noma ibhendi yokumunca encane eduze kuka-976nm. Njengoba i-wavelength yokumpompa isondela ku-lasing wavelength ye-fiber laser, lokho okubizwa ngokuthi i-quantum deficit kuyancishiswa, ukwandisa ukusebenza kahle nokunciphisa inani lokushisa kwemfucuza okudingeka ichithwe.

I-Fiber lasersnamalaser e-diode-pumped solid-state womabili ancike ekwandeni kokukhanya kwei-diode laser. Ngokuvamile, njengoba ukukhanya kwama-laser e-diode kuqhubeka nokuba ngcono, amandla ama-lasers abawampompa nawo ayakhula. Ukuthuthukiswa kokukhanya kwe-semiconductor lasers kuvame ukukhuthaza ukuguqulwa kokukhanya okusebenza kahle kakhulu.

Njengoba silindele, ukukhanya kwendawo kanye ne-spectral kuyodingeka ezinhlelweni zesikhathi esizayo ezizovumela ukupompa okushodayo kwe-quantum ezicini zokumunca emincane kuma-laser wesifunda esiqinile, kanye nezikimu eziminyene zokusebenzisa kabusha ubude begagasi lezinhlelo zokusebenza ze-laser ye-semiconductor eqondile.

Umfanekiso 2: Ukwenyuka kokukhanya kwamandla aphezului-semiconductor lasersivumela izinhlelo zokusebenza ukuthi zinwetshwe

Imakethe kanye nesicelo

Intuthuko kumalaser we-semiconductor enamandla amakhulu yenze izicelo eziningi ezibalulekile zenzeke. Njengoba izindleko zokukhanya ngakunye kwe-watt yama-laser we-semiconductor enamandla amakhulu zehliswe ngokuphawulekayo, lawa ma-lasers womabili athatha indawo yobuchwepheshe obudala futhi anika amandla izigaba zemikhiqizo emisha.

Njengoba izindleko nokusebenza kuthuthukiswa okuphindwe ka-10 njalo eminyakeni eyishumi, ama-laser anamandla aphezulu aphazamise imakethe ngezindlela ezingalindelekile. Nakuba kunzima ukubikezela izinhlelo zokusebenza zesikhathi esizayo ngokunemba, kuyafundisa futhi ukubheka emuva eminyakeni engamashumi amathathu edlule ukuze ucabange amathuba eshumi leminyaka elizayo (bona Umfanekiso 2).

Lapho uHholo ebonisa ama-lases semiconductor eminyakeni engaphezu kwengu-50 edlule, wethula inguquko kwezobuchwepheshe. Njengomthetho kaMoore, akekho obengabikezela impumelelo ekhaliphile yama-laser we-semiconductor anamandla amakhulu alandela ngokuqanjwa okuhlukile okuhlukile.

Ikusasa lama-lases semiconductor
Ayikho imithetho eyisisekelo yefiziksi ebusa lezi ntuthuko, kodwa ukuqhubeka kwezobuchwepheshe kungase kusekele lokhu kuthuthukiswa okuphawulekayo ngobuhle. Ama-laser we-semiconductor azoqhubeka nokuthatha indawo yobuchwepheshe bendabuko futhi azophinde aguqule indlela izinto ezenziwa ngayo. Okubaluleke kakhulu ekukhuleni komnotho, ama-laser we-semiconductor enamandla amakhulu nawo azoshintsha lokho okungenziwa.
