Gukwirakwiza nezalaserimiterere

1, imiterere yumucyo wa pompe

Lazeri ya fibre yambere yakoreshejwe cyane pompe optique isohoka,laseribisohoka, imbaraga zayo zisohoka ni nke, murwego rwo kuzamura byihuse imbaraga zisohoka za fibre lazeri mugihe gito harikibazo gikomeye. Mu 1999, ingufu ziva mubushakashatsi bwa fibre laser hamwe niterambere ryateje imbere watt 10,000 ku nshuro yambere, imiterere ya fibre laser ni ugukoresha pompe optique ya pompe optique, ikora resonator, hamwe niperereza ryakozwe neza murwego rwa fibre lazeri yageze kuri 58.3%.
Nubwo, nubwo ikoreshwa rya fibre pompe yumucyo hamwe na tekinoroji yo guhuza laser kugirango itezimbere fibre fibre irashobora kunoza neza imbaraga ziva mumashanyarazi ya fibre, ariko mugihe kimwe hariho ibintu bitoroshye, bitajyana na optique ya optique yo kubaka inzira ya optique, iyo lazeri ikeneye kwimurwa mugikorwa cyo kubaka inzira ya optique, noneho inzira ya optique nayo igomba kongera guhindurwa, bikagabanya ikoreshwa ryinshi rya fibre optique.

2, imiterere ya oscillator itaziguye n'imiterere ya MOPA

Hamwe niterambere rya fibre lazeri, amashanyarazi yambaraga amashanyarazi yagiye asimbuza buhoro buhoro ibice bigize lens, byoroshya intambwe yiterambere rya fibre fibre no kuzamura mu buryo butaziguye imikorere yimikorere ya fibre. Iterambere ryiterambere ryerekana buhoro buhoro ibikorwa bya fibre. Imiterere ya oscillator itaziguye hamwe na MOPA nuburyo bubiri busanzwe bwa fibre laseri kumasoko. Imiterere ya oscillator itaziguye ni uko urusyo ruhitamo uburebure bwumurongo mugikorwa cyo kunyeganyega, hanyuma rugasohora uburebure bwatoranijwe bwatoranijwe, mugihe MOPA ikoresha uburebure bwumurongo bwatoranijwe no gusya nkurumuri rwimbuto, kandi urumuri rwimbuto rwongerewe imbaraga mugikorwa cya amplifier yo murwego rwa mbere, bityo imbaraga zisohoka za fibre lazeri nazo zizanozwa kurwego runaka. Kumwanya muremure, fibre ya fibre ifite imiterere ya MPOA yakoreshejwe nkuburyo bwatoranijwe kuri fibre ikomeye. Nyamara, ubushakashatsi bwakurikiyeho bwerekanye ko imbaraga nyinshi zisohoka muri iyi miterere byoroshye kuganisha ku ihungabana ryikwirakwizwa ry’imbere imbere ya fibre laser, kandi urumuri rwa laser rusohoka ruzagira ingaruka ku rugero runaka, narwo rukaba rufite ingaruka zitaziguye ku ngaruka zikomeye ziva hanze.

Hamwe no guteza imbere tekinoroji yo kuvoma

Uburebure bwa pompe yuburebure bwa ytterbium-dope fibre laser isanzwe ni 915nm cyangwa 975nm, ariko ubu burebure bubiri bwo kuvoma ni impinga yo kwinjiza ion ya ytterbium, kubwibyo byitwa kuvoma neza, kuvoma neza ntabwo byakoreshejwe cyane kubera gutakaza kwant. Tekinoroji yo kuvoma muri bande niyagurwa rya tekinoroji yo kuvoma mu buryo butaziguye, aho uburebure bwumurongo uri hagati yuburebure bwa pompe nuburebure bwikwirakwizwa bisa, kandi igipimo cyo gutakaza kwantum ya pompe ya bande ni gito ugereranije no kuvoma neza.

Laser power poweriterambere ryikoranabuhanga

Nubwo fibre ya fibre ifite agaciro gakomeye mubikorwa bya gisirikare, ubuvuzi nizindi nganda, Ubushinwa bwateje imbere ikoreshwa rya fibre fibre binyuze mumyaka 30 yubushakashatsi bwikoranabuhanga niterambere, ariko niba ushaka gukora fibre fibre ishobora kubyara ingufu nyinshi, haracyari inzitizi nyinshi mubuhanga buriho. Kurugero, niba imbaraga zisohoka za fibre laser zishobora kugera kuri fibre imwe-imwe 36.6KW; Ingaruka zo kuvoma ingufu kuri fibre laser isohora ingufu; Ingaruka ya lens yumuriro ingaruka kumasoko ya fibre laser.

Byongeye kandi, ubushakashatsi bwubuhanga buhanitse bwo gusohora ingufu za fibre laser bugomba no gutekereza ku guhagarara kwimiterere ya transvers ningaruka zo kwijimye. Binyuze mu iperereza, biragaragara ko ingaruka ziterwa na transvers yuburyo budahungabana ari ugushyushya fibre, kandi ingaruka ya fotone yijimye yerekeza cyane cyane ko iyo fibre lazeri ikomeza gusohora watt amagana cyangwa kilowat nyinshi zingufu, ingufu zisohoka zizerekana kugabanuka byihuse, kandi hariho urugero runaka rwo kugabanuka kumasoko menshi ya fibre laser.

Nubwo impamvu zihariye zitera umwijima wa fotone zitarasobanuwe neza muri iki gihe, abantu benshi bemeza ko ikigo cyangiza ogisijeni hamwe no kwinjiza amafaranga bishobora gutuma habaho ingaruka zijimye. Kuri ibi bintu byombi, inzira zikurikira zirasabwa kubuza ingaruka zijimye. Nka aluminium, fosifore, nibindi, kugirango wirinde kwinjiza amafaranga, hanyuma fibre ikora neza igeragezwa kandi igashyirwa mubikorwa, igipimo cyihariye ni ugukomeza ingufu za 3KW mumasaha menshi kandi ugakomeza ingufu za 1KW mumasaha 100.
