Ukwakheka kwenkqubo ye-laser yefayibha enamandla aphezulu
1, ukwakheka kwenkqubo
I-laser yefayibha enamandla aphezulu inamacandelo amane: umthombo wepompo, umdibanisi wepompo, ifayibha yokufumana inzuzo, kunye nentloko yemveliso ye-laser.
1.1 Umthombo wepompo: Amandla okukhupha idayi enye yelaser yi-10W ~ 50W kuphela, kwaye iidayi ezi-6 ~ 50 ziya kuhlanganiswa kwaye zipakishwe ngokwemfuno; Ukuba kukho inani elikhulu leetships, ukuhlanganiswa kwemitha yendawo kunye nokuhlanganiswa kwemitha ye-polarisation kuya kuhlanganiswa ukwandisa amandla. Amandla omthombo omnye wepompo aqala kumashumi ukuya kumakhulu eewatts, kwaye ukufezekisa imveliso yenqanaba le-kilowatt, kufuneka kudityaniswe imithombo yepompo engaphezulu kwe-10 ngokulandelelana (njengelaser yeRuike kusetyenziswa indibaniselwano yemithombo yepompo eli-11).
1.2 Umdibanisi wepompo: Yenziwe ngetekhnoloji yokudibanisa i-fiber fusion, iimodyuli ezininzi zepompo zidityaniswe ngokubonakalayo kwi-fiber efanayo.
1.3 Ifayibha yoGuquko: enobude obuhlala budlula iimitha ezingama-30, iya kubhijelwa ize inamathele kwipleyiti yokusasaza ubushushu, idla ngokusetyenziswa isakhiwo se-ytterbium doped double cladding: ububanzi obuphakathi be-10-20 μ m, i-single mode/few mode waveguide, efakwe ii-ions ze-ytterbium; Ububanzi be-cladding yangaphakathi bufikelela kwi-400 μ m kwaye isetyenziselwa ukudlulisa ukukhanya kwepompo ye-multi-mode.
1.4 Intloko yesiphumo seLaser: Inoxanduva lokukhupha okokugqibela kwelaser kwaye inokuqhagamshelwa kwizixhobo zokucubungula nge-interface esemgangathweni.
2, Umgaqo osebenzayo ongundoqo
2.1 I-Resonator yokukhulisa ukukhanya: yenziwe ngee-fiber ze-Bragg gratings (ii-FBGs): i-grating ephezulu yokubonakalisa ukukhanya (ukubonakalisa ukukhanya>99%) ibonisa ukukhanya kwe-wavelength ekujoliswe kuyo (njenge-1080nm) ukubuyela kwi-gain fiber; I-output coupled grating (ukubonakalisa ukukhanya okungu-10% ~ 50%) ibonisa ukukhanya okuncinci ukugcina i-oscillation, kwaye idlulisela kancinci ukwenza i-output. Ukukhanya kwepompo kuyavuselela ii-ion ze-ytterbium ukuvelisa i-spontaneous emission, kwaye ii-photons ezihlangabezana neemfuno ze-wavelength ziyandiswa ngokuphindaphindiweyo phakathi kwe-gratings, ekugqibeleni zenze i-stable laser output.
2.2 Ukukhethwa kwendlela kuqinisekisa umgangatho womqadi: Kwelinye icala, kuxhomekeke kumda we-waveguide womaleko omncinci we-core, kuphela ukuhanjiswa kokulahleka okuphantsi kwendlela ye-fundamental okuvunyelweyo; Kwelinye icala, ngokusebenzisa ukudibana okuphezulu phakathi kwendlela ye-fundamental kunye ne-gain medium (ii-ytterbium ions), kunye neempawu zokulahleka okuphezulu kweendlela ze-higher-order, kunye noyilo lwe-fiber bending ukucoca ngakumbi iindlela ze-higher-order, imveliso ye-fundamental mode esemgangathweni ophezulu ene-M² esondela kwi-1 ekugqibeleni ifezekiswa.
