Isishwankathelo samandla aphezului-laser ye-semiconductoruphuhliso icandelo lesibini
I-laser yefayibha.
Iilaser zefayibha zibonelela ngendlela engabizi kakhulu yokuguqula ukukhanya kweelaser ze-semiconductor ezinamandla aphezulu. Nangona ii-optics ze-wavelength multiplexing zinokuguqula iilaser ze-semiconductor ezikhanyayo kancinci zibe zezikhanyayo, oku kuza ngexabiso lokwanda kobubanzi be-spectral kunye nobunzima be-photomechanical. Iilaser zefayibha zibonakalise ukuba zisebenza kakuhle kakhulu ekuguquleni ukukhanya.
Iifayibha ezifakwe kabini ezaqaliswa ngeminyaka yoo-1990, kusetyenziswa isiseko semowudi enye esijikelezwe yi-multimode cladding, zinokungenisa ngempumelelo ii-laser ze-multimode semiconductor pump lasers ezinamandla aphezulu, ezingabizi kakhulu kwifayibha, zenze indlela engabizi kakhulu yokuguqula ii-laser ze-semiconductor ezinamandla aphezulu zibe yimithombo yokukhanya ekhanyayo. Kwiifayibha ze-ytterbium-doped (Yb), ipompo ivuselela ibhendi yokufunxa ebanzi ephakathi kwi-915nm, okanye ibhendi yokufunxa enciphileyo kufutshane ne-976nm. Njengoko ubude be-wavelength yokufunxa busondela kubude be-lasing be-lasing ye-fiber laser, oko kubizwa ngokuba yi-quantum deficit kuyancitshiswa, okwandisa ukusebenza kakuhle kwaye kunciphisa ubungakanani bobushushu obungafunekiyo.
Iilaser zefayibhakunye nee-diode-pumped solid-state lasers zombini zixhomekeke ekwandeni kokukhanya kwe-ileza yediodeNgokubanzi, njengoko ukukhanya kwee-diode lasers kuqhubeka kuphucuka, amandla ee-laser abazimpompayo nawo ayakhula. Ukuphuculwa kokukhanya kwee-semiconductor lasers kudla ngokukhuthaza ukuguqulwa kokukhanya okusebenzayo ngakumbi.
Njengoko silindele, ukukhanya kwendawo kunye ne-spectral kuya kufuneka kwiinkqubo zexesha elizayo eziya kuvumela ukupompa kwe-quantum deficit ephantsi kwiimpawu zokufunxa ezincinci kwi-solid-state lasers, kunye neenkqubo zokusebenzisa kwakhona ubude be-wavelength obude kwizicelo ze-semiconductor laser ngqo.

Imakethi kunye nesicelo
Inkqubela phambili kwi-laser ze-semiconductor ezinamandla aphezulu yenze ukuba kubekho usetyenziso oluninzi olubalulekileyo. Ekubeni ixabiso le-watt yokukhanya nganye ye-laser ze-semiconductor ezinamandla aphezulu liye lehla ngokukhawuleza, ezi laser zombini zithatha indawo yetekhnoloji endala kwaye zivumela iindidi ezintsha zemveliso.
Njengoko iindleko kunye nokusebenza kuphucuka ngaphezu kwezihlandlo ezili-10 kwishumi leminyaka, ii-laser ze-semiconductor ezinamandla aphezulu ziye zaphazamisa imarike ngeendlela ezingalindelekanga. Nangona kunzima ukuqikelela usetyenziso lwexesha elizayo ngokuchanekileyo, kuyanceda ukujonga emva kwiminyaka engamashumi amathathu edlulileyo ukuze ucinge ngamathuba eminyaka elishumi ezayo (jonga uMfanekiso 2).
Xa uHall wabonisa iileyiza ze-semiconductor kwiminyaka engaphezu kwama-50 eyadlulayo, waqalisa utshintsho kwezobuchwepheshe. NjengoMoore's Law, akukho mntu wayenokuqikelela impumelelo eqaqambileyo yeeleyiza ze-semiconductor ezinamandla aphezulu ezalandela ngeentlobo ngeentlobo zezinto ezintsha ezahlukeneyo.
Ikamva le-semiconductor lasers
Akukho mithetho isisiseko yefiziksi elawula olu phuculo, kodwa ukuqhubeka kwenkqubela phambili kwezobuchwepheshe kusenokwenzeka ukuba kuqhubeke nolu phuhliso lubalaseleyo. Iilaser ze-semiconductor ziya kuqhubeka zithatha indawo yetekhnoloji yendabuko kwaye ziya kutshintsha ngakumbi indlela ezenziwa ngayo izinto. Okubaluleke ngakumbi ekukhuleni koqoqosho, iilaser ze-semiconductor ezinamandla aphezulu ziya kutshintsha noko kunokwenziwa.
