Fiber laser cutting le Medical
Fiber laser ho itšeha le meriana, faeba laser ho itšeha mochini e doped faeba ka boeona e e le ntho e sebetsang, le faeba tham mong bang laser ho itšeha mochine ka boeona, empa hape phetha karolo ea tataiso leqhubu tiileng-se mmuso laser.Resonator, e na le ntho e sebetsang, mohloli oa pompo likarolo tse tharo tsa motheo.Lilemong tsa morao tjena, li-laser tsa fiber masimong a indasteri ho kenyelletsa lits'ebetso tse fapaneng, le botumo bo ntseng bo eketseha lefapheng la bongaka.
Fiber Technology Center, Univesithi ea Sydney, Australia (OFT C) ea Stuart Jackson e itse: "Fiber laser cutting machine bakeng sa likopo tsa ho buoa, ke habohlokoa ho kopanya lasers, tlhokomelo e fokolang, bokhoni bo phahameng bo phahameng le thepa e ntle ea mocheso oa laser fiber.li etsa hore li tšoanelehe ka ho khetheha bakeng sa lits'ebetso tsa ho buoa hobane li sebelisa diode-pumped, kahoo e kopane haholo.Sebopeho sa fiber ho feta sesebediswa sa laser se tiileng se phahame hobane se nolofaditse tlhokeho ya faeba e eketsehileng ya phetiso, ka hona se fokotsa ditjeo le ho fokotsa ho rarahana ha sistimi”.
Fiber laser cutting machine ka 1963 ke Elias Spritzer e qapiloeng.Pele o qetella o kene ts'ebeliso ea khoebo, kamora lilemo tse ka bang peli tsa nako ea ntlafatso.Qalong, tšebeliso ea laser diode e le 'ngoe e pompetsoe, ke mahlaseli a mashome a milliliters feela.Empa e na le basebelisi ba bangata ba ntseng ba khahleha ka lebaka la phaello ea bona e phahameng, e ka etsa ts'ebetso e ngata e tsoelang pele ea mofuta o le mong oa li-ion tsa lefatše tse sa tloaelehang, e leng laser ea kristale e ke keng ea finyelloa.1990, fiber lasers ho fihlela leap-watt output stage, joale, e tlalehile erbium-doped fiber laser output power up 4 W, ntshetsopele ena kajeno re bona matla a 10 W le phahameng single-mode fiber lasers motheo.
Mochineng oa ho itšeha oa laser, fiber ka boeona e sebetsa e le sekoti sa resonant.Lisebelisoa tsena hangata li na le erbium doped single-mode core ytterbium (kapa metsoako ea eona), kapa ntho e sa tloaelehang ea lefatše.Matla a tsoang mohloling o tiileng oa leseli, a hokahana le ho koaheloa ha fiber, ebe ho ea bohareng, pompo e etsa liathomo.Lefapheng la bongaka, bolelele ba maqhubu bo hlokahala haholo ke: 1.3μm sehlopha sa litšoantšo, 1.5μm (tlhōrō ea ho monya metsi) -4μm bakeng sa ho buuoa, ho tloha matleng a matla a milliliters ho ea ho 100 W.
Jackson o itse: "Tšebeliso ea li-laser tsa CW, lits'ebetso tsa biomedical, haholo-holo leha e le efe ea matla a phahameng a CW lasers, e ka rua molemo ho tloha mochine oa ho itšeha ka laser fiber ka mochine oa ho itšeha oa faeba o fana ka katleho e phahameng, mefuta e mengata ea ho lokisa, le tlhahiso eohle.matla a marang-rang a na le molemo oa boleng bo betere, haholo-holo bo hlahelletseng;e le hore li-laser tsa fiber li fapane lits'ebetsong tsa bongaka li tsoela pele ho hola.“
