Ibisobanuro bya Diode ya Laser ihujwe na Fibre, Ihame ry'Umurimo, n'Uburebure bw'Umuraba Usanzwe
Diode ya laser ifatanye na fibre ni igikoresho cya semiconductor gitanga urumuri rufatanye, hanyuma rushyirwa ku murongo neza kugira ngo ruhuzwe n'insinga ya fiber optique. Ihame ry'ingenzi rikubiyemo gukoresha amashanyarazi kugira ngo atere imbaraga diode, hakorwe fotoni binyuze mu ibyuka bishyushye. Izi fotoni zongerwa muri diode, zigatanga urumuri rwa laser. Binyuze mu kwibanda no guhuza neza, uyu muyoboro wa laser uyoborwa mu mutima wa fibre optique, aho woherezwa nta gihombo kinini bitewe no kugaragara imbere mu kirere.
Ingano y'uburebure bw'umuraba
Ubunini bw'uburebure busanzwe bwa module ya laser diode ifatanye na fiber bushobora gutandukana cyane bitewe n'uburyo ikoreshwa. Muri rusange, ibi bikoresho bishobora gukwirakwiza uburebure butandukanye bw'uburebure, harimo:
Urumuri rugaragara:Kuva kuri nm 400 (violet) kugeza kuri nm 700 (umutuku). Ibi bikunze gukoreshwa mu bikorwa bisaba urumuri rugaragara kugira ngo rumurike, rugaragare, cyangwa rubone.
Imirasire y'urumuri hafi ya infrared (NIR):Ifite ubunini buri hagati ya nanometero 700 na nanometero 2500. Ubunini bwa NIR bukunze gukoreshwa mu itumanaho, mu buvuzi, no mu nganda zitandukanye.
Imirasire yo hagati ya infrared (MIR): Irenga 2500 nm, nubwo idakunze kugaragara muri module zisanzwe za laser diode zifatanye na fibre bitewe n'ibikoresho byihariye n'ibikoresho bya fibre bikenewe.

Ibisabwa ku isoko ya pompe ya fiber lasers na solid-state lasers.
Kugira ngo usobanukirwe neza ibisabwa ku isoko y'ipompo kuri laser za fibre na laser za solid-state, ni ngombwa gusuzuma umwihariko w'uko izi laser zikora n'uruhare rw'amasoko ya pompe mu mikorere yazo. Hano, turagura incamake y'ibanze kugira ngo dusobanukirwe imiterere y'uburyo bwo gupompa, ubwoko bw'amasoko ya pompe akoreshwa, n'ingaruka zabyo ku mikorere ya laser. Guhitamo no gushyiraho amasoko ya pompe bigira ingaruka ku buryo butaziguye ku mikorere ya laser, imbaraga zo gusohora, n'ubwiza bw'imirasire. Guhuza neza, guhuza uburebure bw'umuraba, no gucunga ubushyuhe ni ingenzi mu kunoza imikorere no kongera igihe cy'ubuzima bwa laser. Iterambere mu ikoranabuhanga rya diode ya laser rikomeje kunoza imikorere n'ubwizerwe bwa laser za fibre na solid-state, bigatuma zirushaho gukoreshwa neza kandi zihendutse ku buryo butandukanye.
- Ibisabwa ku isoko rya pompe ya Fiber Laser
Diode za Lazerink'amasoko ya pompe:Fiber lasers zikoresha cyane cyane laser diodes nk'isoko yazo ya pompe bitewe n'ubushobozi bwazo, ingano nto, n'ubushobozi bwo gukora uburebure bw'urumuri runaka bujyanye n'uburyo fibre ya doped. Guhitamo uburebure bwa laser diode ni ingenzi; urugero, dopant isanzwe muri fibre lasers ni Ytterbium (Yb), ifite uburebure bwiza bwo kwinjiza hafi ya 976 nm. Kubwibyo, laser diodes zisohora kuri ubu burebure cyangwa hafi y'ubu ni zo zikundwa cyane mu gukurura fiber lasers ya Yb.
Igishushanyo mbonera cy'imigozi ibiri:Kugira ngo bongere ubushobozi bwo kwinjiza urumuri muri pompe laser diodes, fibre lasers akenshi zikoresha imiterere ya fibre ifite ibice bibiri. Imbere y'imbere igizwe n'icyuma cya laser gikora (urugero, Yb), mu gihe urwego runini rwo hanze ruyobora urumuri rwa pompe. Imbere y'imbere ifata urumuri rwa pompe igakora igikorwa cya laser, mu gihe icyuma gitera urumuri rw'ipompe gukora cyane, bityo bigatuma urumuri rurushaho kuba rwinshi mu rumuri rwa pompe rukorana n'urumuri rwayo, bityo rukongera ubushobozi bwo gukora neza.
Guhuza Uburebure bw'Umuraba n'Uburyo Bunoze bwo Guhuza: Gukoresha neza pompe ntabwo bisaba gusa guhitamo diode za laser zifite ubunini bw'uburebure bukwiye, ahubwo bisaba no kunoza imikorere myiza hagati ya diode na fibre. Ibi bisaba gushyira hamwe witonze no gukoresha ibice by'urumuri nka lenses na couplers kugira ngo urumuri rw'ipompe rwinjizwe mu gice cy'imbere cya fibre cyangwa mu gipfundikizo.
-Lazeri zo mu rwego rwo hejuruIbisabwa ku isoko ry'ipompo
Pompe y'amatara:Uretse diode za laser, laser za solid-state (harimo na laser nyinshi nka Nd:YAG) zishobora gutangwaho amatara ya flash cyangwa amatara ya arc. Aya matara atanga urumuri rwinshi, igice kimwe cyarwo kikaba gihuye n'imirongo yo kwinjizamo ya laser. Nubwo idakora neza nka laser diode pumping, ubu buryo bushobora gutanga ingufu nyinshi cyane, bigatuma bukoreshwa mu gukoresha ingufu nyinshi.
Imiterere y'Isoko rya Pompe:Imiterere y'isoko ry'ipompo muri laser za state solid-state ishobora kugira ingaruka zikomeye ku mikorere yazo. Gutanga pompe no kugabanya uruhande ni imiterere isanzwe. Gutanga pompe, aho urumuri rwa pompe ruyoborwa ku murongo w'urumuri rwa laser, bitanga uburyo bwiza bwo guhuza urumuri rwa pompe n'uburyo bwa laser, biganisha ku musaruro mwiza. Gutanga pompe kuruhande, nubwo bishobora kudakora neza, biroroshye kandi bishobora gutanga ingufu nyinshi muri rusange ku nkoni nini cyangwa slabs.
Imicungire y'ubushyuhe:Lazeri zombi za fibre na solid-state zikenera gucunga neza ubushyuhe kugira ngo zicunge ubushyuhe buturuka ku masoko ya pompe. Muri lazeri za fibre, ubuso bwagutse bwa fibre bufasha mu gukwirakwiza ubushyuhe. Muri lazeri za solid-state, sisitemu zo gukonjesha (nk'ubukonje bw'amazi) zirakenewe kugira ngo zikomeze gukora neza no gukumira ko ubushyuhe butera cyangwa kwangiza icyuma cya laser.
