Imiterere y'ibanze ya laser ya fiber imwe

Imiterere y'ibanze yalaser ya fibre yo mu buryo bumwe

Imikorere myiza cyane ya single-modelaser ya fibreBikomoka ku miterere yabyo y’imbere. Imikorere myiza y’ubufatanye hagati y’ibice byose ni ishingiro ryo kugera ku musaruro uhamye kandi w’ubuziranenge wa laser.

Urugero, laser ya 976nm ifite ubushobozi bwo guhindura amashanyarazi buhanitse ikoreshwa mu gushyushya fibre ya doped, hanyuma itara ry'imbuto rya 1064nm rifite ubwiza bwiza rikoreshwa mu kuyobora fibre ya doped ya doped kugira ngo irekure laser ya 1064nm ifite ingufu nyinshi. Uko ingufu za laser ya 1064nm zikenewe ziba nyinshi, niko ingufu n'ingano by'isoko y'ipompo bikenerwa byiyongera.

Ibisobanuro birambuye by'ibice by'ingenzi

Isoko y'ipompe ni isoko y'ingufu z'imashinilaser, ubusanzwelaser ya semiconductordiode, uburebure bw'umuvuduko wayo buhuye n'urugero rw'umuvuduko w'ubushyuhe bw'umusaruro (urugero, fibre ifite ytterbium ihuye n'uburebure bw'umuvuduko wa 915nm cyangwa 976nm). Laser y'uburyo bumwe isaba ko isoko y'urumuri rwa pompe nayo igira ubwumvikane buhanitse. Kubwibyo, diode za laser z'uburyo bumwe zikunze gukoreshwa kugira ngo urumuri rwa pompe rushobore gushyirwa neza mu gice cy'imbere cy'umunyu mwiza w'uburyo bumwe.

2. Imigozi ya Gain ni yo ikoreshwa cyane mu gukora laser kandi akenshi ni imigozi ya quartz igizwe n'ibintu bidasanzwe by'ubutaka. Iyoni zisanzwe zigizwe na ytterbium (Yb³⁺), erbium (Er³⁺), thulium (Tm³⁺), nibindi, bihuye n'imirongo itandukanye y'uburebure bw'umuvuduko (nka 1064nm, 1550nm, 2μm, nibindi). Uburebure bwa fibre ya gain bugomba gutegurwa neza kugira ngo bufashe neza urumuri rwa pompe mu gihe bukomeza guhindura opto-optical neza cyane.

3. Uburyo bukunze gukoreshwa cyane mu gushyira mu bikorwa umwobo w’urumuri ni utwo duce twa Bragg two gukurura. Utwo duce dukurura rukorwa binyuze mu gushyira umwobo w’urumuri ku mpande z’urumuri rwa ultraviolet, bigatera impinduka zihoraho mu gipimo cyo kugarura ubushyuhe mu bice by’ibanze byarwo. Mu kugenzura igihe n’uburebure byarwo, uburebure bw’umurambararo n’uburebure bw’urumuri bishobora kugenzurwa neza. Iyi miterere y’umwobo w’urumuri rw’urumuri rwuzuye ntisaba ibice bitandukanye nk’amatara y’urumuri, bikongera cyane ubushobozi bwo kudahungabanya no kurwanya ingaruka mbi z’urumuri.

4. Sisitemu yo gusohora urumuri rw'imirasire isanzwe iba iri inyuma y'urumuri rusohoka. Akazi kayo ni uguhindura lazeri isohoka mu miringoti y'urumuri ihinduka urumuri ruhuriranye cyangwa kuyishyira ku buso bw'akazi. Ubusanzwe iyi sisitemu igizwe n'amalenzi yibanda ku giti cyayo cyangwa amatsinda y'amalenzi magufi kandi ikoresha imiterere nyayo ya mekanike kugira ngo irebe ko ihuye neza. Igishushanyo mbonera cy'urumuri cyiza gishobora kugabanya amakosa no kwemeza ko urumuri rusohoka rugumana ikwirakwizwa ryiza rya Gaussian.
