Yethula i-high-power yakamuvaumthombo wokukhanya we-laser
Imithombo emithathu yokukhanya kwe-laser eyinhloko ifaka umfutho onamandla ezinhlelweni zokusebenza ze-optical ezinamandla aphezulu
Emkhakheni wezinhlelo zokusebenza ze-laser eziphishekela amandla amakhulu kanye nokuzinza okuphelele, izixazululo zephampu kanye ne-laser ezisebenza kahle kakhulu bezilokhu zigxile embonini. Namuhla, sethula ikakhulukazi imikhiqizo emithathu eyinhloko evelele ngokusebenza kanye nokuthembeka: imithombo yokukhanya ye-laser epomped eyodwa, imithombo yokukhanya ye-laser epomped eminingi, kanye ne-1550nm continuous fiber lasers (CW laser), ekusiza ukuthi wenze imizamo eqondile ocwaningweni lwesayensi kanye nezinhlelo zokusebenza zezimboni.
Umthombo wokukhanya we-laser opompiwe wemodi eyodwa
Akuyona nje umthombo wokukhanya kodwa futhi “inhliziyo enamandla” yesistimu efunwa kakhulu. Isebenzisa imodi eyodwai-laser ye-semiconductornge-grating ye-FBG ezinzile ngobude be-wavelength, engakhipha i-laser enobude be-wavelength obuzinzile kakhulu namandla aqinile. Yenzelwe izinhlelo zokusebenza ezidinga amandla amaningi njenge-high-power fiber amplifier kanye ne-mode-lockedi-fiber laserSiyazi kahle usongo olungaba khona lokukhanya kwe-ASE okukhiqizwa yizintambo ze-optical ezisebenzayo emthonjeni wephampu. Ngakho-ke, sakhe ngokukhethekile indlela yokuvikela iphampu eqondiwe ukwakha umugqa wokuzivikela oqinile ukuze uhlelo lwakho lusebenze ngokuphephile.
2. Umthombo wokukhanya we-laser opompiwe we-Multimode
Faka amandla anamandla kui-laser enamandla aphezulukanye nama-amplifier. Ifakwe i-laser epompiwe nge-single-tube esebenza kahle kakhulu, efinyelela ibhalansi ephelele phakathi kwamandla aphezulu nokukhanya okuphezulu. Ingaphakathi layo uhlelo lokulawula oluhlakaniphile oluhlanganiswe ne-microprocessor ethuthukisiwe, oluhlanganiswe namasekethe e-ATC (Automatic Temperature Control) anembile kakhulu kanye ne-ACC/APC (Automatic current/Power Control), ukuqinisekisa ukuphuma okuzinzile kakhulu. Ukusebenza kunembile futhi kulula, futhi kusekela izixhumi zokuxhumana ezenziwe ngokwezifiso kanye nesofthiwe yokulawula, okwenza ukuhlanganiswa kanye nokulawula okuzenzakalelayo kube lula ukukufinyelela.
3.1550nmI-laser ye-CW
Ngokusekelwe ebhendini "yokuphepha kwamehlo", sivula isahluko esisha ekusetshenzisweni kwamandla aphezulu. Sisebenzisa umklamo ohlanganisiwe we-fiber yonke, ngenxa yobuchwepheshe bokupompa i-fiber obumbozwe kabili, singakhipha ngokuzinzile ama-laser asebenza kahle asukela ku-200mW kuya ku-10W. Uhlelo lokulawula olusekelwe kuma-microprocessor luqinisekisa ukuzinza kwalo kokusebenza kwesikhathi eside kanye nezici ezingenakulungiswa. Iphaneli engaphambili yemodeli yedeskithophu ifakwe isikrini sokubonisa se-LCD, esingaqapha amapharamitha abalulekile njengamandla nokushisa kanye nolwazi lwe-alamu ngesikhathi sangempela. I-interface icacile ngokushesha futhi ukusebenza kulula ukuyiqonda. Ngesikhathi esifanayo, sinikeza nezinketho zokupakisha eziguquguqukayo, ezenza kube lula kakhulu ukuhlanganiswa kwesistimu yakho.
Kungakhathaliseki ukuthi ukuphishekela ukuzinza okuphelele ezidingweni zokupompa noma isidingo sokukhishwa kwe-laser enamandla aphezulu ngokuphepha kwamehlo okuphezulu, uhla lwemikhiqizo yethu lunganikeza izixazululo zobungcweti nezithembekile.
