Fiber lasers tšimong ea puisano ea fiber optical

TheFiber Lasere bua ka laser e sebelisang likhoele tse sa tloaelehang tsa khalase e le 'ngoe e le mokhoa oa ho fumana chelete. Li-laser tsa fiber li ka ntlafatsoa ho ipapisitsoe le li-amplifiers tsa fiber, 'me molao-motheo oa tsona oa ts'ebetso ke: nka mohlala oa laser ea longitudinally pumped fiber. Karolo ea fiber e nang le li-ion tsa tšepe tse sa tloaelehang e behiloe pakeng tsa liipone tse peli tse nang le ponahalo e khethiloeng. Leseli la pompo le kopanya fiber ho tloha seiponeng se letšehali. Seipone se letšehali se fetisa leseli lohle la pompo 'me se bonahatsa laser ka ho feletseng, e le hore se sebelise khanya ea pompo ka katleho le ho thibela leseli la pompo hore le se ke la khanya le ho baka khanya e sa tsitsang ea tlhahiso. Endoscope e nepahetseng e lumella karolo ea laser ho feta e le hore e thehe maikutlo a lebone la laser le ho fumana tlhahiso ea laser. Li-photons tse bophahamong ba maqhubu a pompo li mongoa ke mahareng, li etsa phetoho ea nomoro ea ion, 'me qetellong li hlahisa tlhahiso e hlasimollang ka har'a fiber e nang le doped ho ea ho laser e hlahisoang.

Litšobotsi tsa li-laser tsa fiber: Ts'ebetso e phahameng ea ho kopanya hobane laser medium ka boeona ke waveguide medium. Ts'ebetso e phahameng ea phetoho, moeli o tlase le phello e ntle ea ho senya mocheso; E na le mefuta e mengata ea ho hokahanya, ho hasana hantle le botsitso. Li-laser tsa fiber le tsona li ka utloisisoa e le sesebelisoa se sebetsang hantle sa wavelength, ke hore, ho fetola bolelele ba maqhubu a leseli la pompo ho ba bolelele ba maqhubu a li-ion tse sa tloaelehang tsa lefatše. Leqhubu lena la lasing wavelength ke hantle feela khanya e hlahisoang ke laser fiber. Ha e laoloe ke bolelele ba pompo ea pompo mme e khethoa feela ke likarolo tse sa tloaelehang tsa doping tsa lefats'e ka har'a thepa. Ka hona, li-lasers tsa semiconductor tsa maqhubu a makhutšoane a fapaneng le matla a phahameng a tsamaellanang le pono ea ho monya ea li-ion tse sa tloaelehang tsa lefatše li ka sebelisoa e le mehloli ea pompo ho fumana liphetho tsa laser tsa maqhubu a fapaneng a fapaneng.

Fiber laser classification: Ho na le mefuta e mengata ea fiber lasers. Ho latela mokhoa oa ho fumana chelete, li ka hlalosoa e le: li-laser tsa fiber tse sa tloaelehang tsa lefats'e, li-laseser tsa fiber tse se nang moeli, li-laseser tsa fiber tse le 'ngoe tsa kristale, le laser fiber fiber. Ho ea ka sebopeho sa fiber, li ka aroloa ka: lasers ea fiber e nang le seaparo se le seng le lisebelisoa tse peli tsa fiber lasers. Ho ea ka likarolo tsa doped, li ka aroloa ka mefuta e fetang leshome e kang erbium, neodymium, praseodymium, joalo-joalo Ho ea ka mokhoa oa ho phunya, e ka khetholloa e le: optical fiber end face pumping, micro prism side optical coupling pumping, ring pumping, joalo-joalo Ho ea ka sebopeho sa "fiber cavity" ea resonant, FP laser cavity, FP . lasers, "8" shaped cavity lasers, joalo-joalo Ho ea ka mokhoa oa ho sebetsa, li ka khetholloa e le: pulsed optical fiber le continuous laser, joalo-joalo.li-laser tse matla haholo, lisebelisoa tsa laser tsa ultrashort pulse, leli-lasers tse ka tšesaaneng tse nang le bophara ba melali hlaha ka ho latellana. Ka mor'a moo, li-laser tsa fiber li tla tsoela pele ho hola ka lehlakoreng la matla a phahameng a hlahisoang, boleng bo betere ba mabone, le litlhoro tse phahameng tsa pulse.
