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 nubushakashatsi bwiterambere byacitse watts 10,000 ku nshuro yambere, imiterere ya fibre laser ni ugukoresha pompe optique yerekanwa, ikora resonator, hamwe niperereza ryakozwe neza rya fibre laser yageze kuri 58.3%.
Nubwo, nubwo gukoresha fibre pompe yumucyo hamwe na tekinoroji ya laser yo guteza imbere fibre fibre irashobora kuzamura neza imbaraga ziva mumashanyarazi ya fibre, ariko mugihe kimwe hariho ibintu bitoroshye, bidafasha lensike ya optique kugirango yubake inzira nziza, lazeri imaze gukenera kwimurwa mugikorwa cyo kubaka inzira ya optique, noneho inzira ya optique nayo igomba kongera guhindurwa, igabanya ikoreshwa ryinshi rya optique ya pompe yububiko bwa fibre.

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 rugasohoza uburebure bwatoranijwe, mugihe MOPA ikoresha uburebure bwumurongo bwatoranijwe no gusya nkurumuri rwimbuto, kandi urumuri rwimbuto rwongerewe mubikorwa byambere. -kwerekana neza, bityo imbaraga zisohoka za fibre laser nayo izanozwa 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 muriyi miterere byoroshye kuganisha ku ihungabana ryikwirakwizwa ryimbere imbere ya fibre lazeri, kandi urumuri rwa lazeri ruzagira ingaruka ku rugero runaka, narwo rukagira ingaruka zitaziguye. ku mbaraga-zisohoka zisohoka.

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 igera kuri 30 yubushakashatsi niterambere, ariko niba ushaka gukora fibre fibre ishobora kubyara ingufu nyinshi, haracyariho 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 lens yumuriro ku mbaraga zisohoka za 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 zijimye za fotone zerekeza cyane cyane ko iyo fibre laser ikomeza gusohora watt amagana cyangwa kilowat nyinshi zingufu, ingufu zisohoka zizerekana a kugabanuka byihuse, kandi hariho urwego runaka rwo kugarukira kumurongo uhoraho w'amashanyarazi 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.
