Isishwankathelo samandla aphezulusemiconductor laseruphuhliso inxalenye yesibini
Ifayibha laser.
I-Fiber lasers ibonelela ngendlela eneendleko zokuguqula ukuqaqamba kwe-laser ye-semiconductor yamandla aphezulu. Nangona i-wavelength multiplexing optics inokuguqula i-laser ye-semiconductor ekhanyayo ephantsi ibe yinto eqaqambileyo, oku kuza kwiindleko zokunyuka kobubanzi be-spectral kunye nobunzima be-photomechanical. Iifiber lasers zingqineke zisebenza ngakumbi kuguqulo lokukhanya.
Iifiber ezifakwe kabini ezifakwe kwi-1990s, zisebenzisa imowudi enye ejikelezwe yi-multimode cladding, inokwazisa ngokufanelekileyo amandla aphezulu, ixabiso eliphantsi le-multimode semiconductor pump lasers kwifiber, ukudala indlela yoqoqosho ngakumbi yokuguqula i-laser ye-semiconductor yamandla aphezulu. kwimithombo yokukhanya eqaqambileyo. Kwiintsinga ze-ytterbium-doped (Yb), impompo ivuselela ibhendi yokufunxa ebanzi egxile kwi-915nm, okanye ibhanti yokufunxa emxinwa kufutshane ne-976nm. Njengoko i-wavelength yokupompa isondela kwi-lasing wavelength ye-fiber laser, into ebizwa ngokuba yi-quantum deficit iyancitshiswa, ukwandisa ukusebenza kakuhle kunye nokunciphisa ubushushu benkunkuma obufuna ukuchithwa.
Iifayibha laserskunye ne-diode-pumped solid-state lasers zombini zixhomekeke ekwandeni kokuqaqamba kwelaser diode. Ngokubanzi, njengoko ukukhanya kwee-lasers ze-diode kuqhubeka nokuphucula, amandla ee-lasers abazimpompa nawo ayanda. Ukuphuculwa kokukhanya kwee-lasemiconductor lasers kuthande ukukhuthaza ukuguqulwa kokukhanya okusebenzayo ngakumbi.
Njengoko silindele, ukukhanya kwendawo kunye nokukhanya okubonakalayo kuya kuba yimfuneko kwiinkqubo zexesha elizayo eziya kwenza ukuba intsilelo ye-quantum ephantsi yokumpompa kwiimpawu zokufunxa ezimxinwa kwii-laser zombuso oqinileyo, kunye nezikimu ezishinyeneyo zokuphinda zisetyenziswe kwi-laser ye-semiconductor ngokuthe ngqo.

Imarike kunye nesicelo
Ukuqhubela phambili kwi-laser ye-semiconductor ephezulu yenze izicelo ezininzi ezibalulekileyo zenzeke. Ukusukela ukuba ixabiso le-watt nganye yokuqaqamba kwe-laser ye-semiconductor yamandla aphezulu liye lancitshiswa kakhulu, ezi lasers zombini zithatha indawo yetekhnoloji endala kwaye zenza iindidi zemveliso entsha.
Ngeendleko kunye nokusebenza okuphuculweyo ngaphezu kwe-10-iminyaka yonke elishumi, i-laser ye-semiconductor yamandla aphezulu iphazamise imarike ngeendlela ezingalindelekanga. Nangona kunzima ukuqikelela usetyenziso lwexesha elizayo ngokuchanekileyo, kuyafundisa kwakhona ukujonga emva kwiminyaka engamashumi amathathu edlulileyo ukucinga okunokwenzeka kwishumi leminyaka elizayo (jonga uMfanekiso 2).
Xa iHolo yabonisa iisemiconductor lasers ngaphezu kweminyaka engama-50 eyadlulayo, wasungula inguqu kwezobuchwepheshe. Njengomthetho kaMoore, akukho mntu wayenokuqikelela impumelelo eqaqambileyo yee-lases ze-semiconductor zamandla aphezulu ezilandele ngeendlela ezahlukeneyo ezintsha.
Ikamva lelaser zesemiconductor
Akukho mithetho isisiseko yefiziksi elawula olu phuculo, kodwa inkqubela phambili yetekhnoloji inokugcina olu phuhliso lubalaseleyo kubuhle. I-lasemiconductor lasers iya kuqhubeka ithatha indawo yetekhnoloji yemveli kwaye iya kutshintsha ngakumbi indlela izinto ezenziwa ngayo. Okubaluleke ngakumbi kuhlumo loqoqosho, iilaser ze-semiconductor ezinamandla kakhulu ziya kutshintsha into enokwenziwa.
