Ubumwe bw'Ikwirakwizwa ry'Ibyiza mu Mirongo yo Gutanga Diode: Urufunguzo rwo Gutuma Imikorere Idahinduka

Mu ikoranabuhanga rya none rya laser, modules za diode pumping zabaye isoko nziza ya pompes za solid-state na fibre lasers bitewe n'ubushobozi bwazo bwo hejuru, kwizerwa, no gushushanya kwazo guto. Ariko, kimwe mu bintu by'ingenzi bigira ingaruka ku musaruro wazo n'ubudahangarwa bwa sisitemu ni uburyo bumwe bwo gukwirakwiza umusaruro muri module ya pompe.

1. Ubwinshi bw'igabanywa ry'inyungu (Gain Distribution Uniformity) ni iki?

Muri modules za diode pumping, utubari twinshi twa laser diode dutondetse mu buryo butandukanye, kandi urumuri rwabyo rwa pompe rushyirwa mu buryo bwo gukuramo umusaruro (nk'udupira twa Yb cyangwa kristale ya Nd:YAG) binyuze muri sisitemu y'urumuri. Iyo ikwirakwizwa ry'imbaraga z'urumuri rwa pompe ritangana, bituma habaho kwiyongera kudahuje mu buryo bw'urumuri, bigatuma:

①Ubwiza bw'umurabyo wa laser bwagabanutse

②Kugabanuka k'ubushobozi bwo guhindura ingufu muri rusange

③Ubwiyongere bw'ubushyuhe n'igihe cy'ubuzima bw'urusobe rw'ibintu

④Ingaruka nyinshi zo kwangirika kw'amaso mu gihe cyo gukora

Kubwibyo, kugera ku buryo bumwe mu gukwirakwiza urumuri rwa pompe ni intego y'ingenzi mu bya tekiniki mu gushushanya no gukora module za pompe.

2. Impamvu zikunze gutera ikwirakwizwa ry'ingufu zitari zimwe

①Impinduka mu ngufu zisohora Chip

Udupira twa laser diode dusanzwe tugaragaza impinduka mu mbaraga. Hatabayeho gutondeka neza cyangwa kwishyura, iri tandukaniro rishobora gutuma ingufu za pompe zidahindagurika mu gace kagenewe.

②Amakosa muri sisitemu yo guhuza no gusesengura

Kutagera ku murongo cyangwa inenge mu bice by’urumuri (urugero, lenzi za FAC/SAC, imirasire ya microlens, fibre couplers) bishobora gutuma ibice by’urumuri bitandukira ku ntego byagenewe, bigatuma habaho ahantu hashyuha cyangwa uturere twapfuye.

③Ingaruka z'ubushyuhe

Imashini zikoresha amashanyarazi zikoresha amashanyarazi zihuta cyane mu bushyuhe. Imiterere mibi ya heatsink cyangwa ubukonje butaringaniye bishobora gutuma uburebure bw'umuraba buhindagurika hagati y'udupira dutandukanye, bigatera ingaruka ku mikorere myiza y'imashini zikoresha amashanyarazi ndetse n'uburyo zikora neza.

④Igishushanyo mbonera cy'umuyoboro wa fibre kidahagije

Mu miterere y’ibisohoka bifite fibre nyinshi cyangwa imirasire ivanze, imiterere idakwiye y’imirasire ishobora no gutuma urumuri rw’ipompo rudakwirakwira mu buryo bumwe mu buryo bwo gukusanya.

3. Amayeri yo kunoza uburyo bwo kugera ku rugero rumwe

①Gutondekanya Chips no Guhuza Ingufu

Suzuma neza kandi ushyire hamwe utubumbe twa diode ya laser kugira ngo urebe ko ingufu zisohoka zihoraho muri buri module, ugabanye ubushyuhe bukabije kandi wongere ahantu hashyuha cyane.

②Igishushanyo mbonera cy'amatara cyiza

Koresha optique idakoresha amashusho cyangwa lenses zihuza (urugero, microlens arrays) kugira ngo wongere ubushobozi bwo gushyira hamwe imirasire no gushimangira neza, bityo utume pompe igaragara neza.

③Imicungire myiza y'ubushyuhe

Koresha ibikoresho bitwara ubushyuhe bwinshi (urugero, CuW, CVD diamond) hamwe n'ingamba zimwe zo kugenzura ubushyuhe kugira ngo ugabanye ihindagurika ry'ubushyuhe hagati ya chip na chip no kubungabunga umusaruro uhamye.

④Ubwinshi bw'Umucyo mu Iterambere ry'Urumuri

Shyiramo ibintu bitanga urumuri cyangwa ibikoresho bihindura imiterere y'urumuri ku nzira y'urumuri rwa pompe kugira ngo urumuri rugere ku rwego rumwe mu buryo bwo gukwirakwiza urumuri.

4. Akamaro gafatika mu bikorwa bifatika

Muri sisitemu za laser zigezweho—nko gutunganya neza inganda, gushyiraho imirasire ya gisirikare, ubuvuzi, n'ubushakashatsi bwa siyansi—Ubudahangarwa n'ubwiza bw'umurabyo wa laser ni ingenzi cyane. Ikwirakwizwa ry'uburumbuke budahuje bigira ingaruka zitaziguye ku bwizerwe n'ubuziranenge bwa sisitemu, cyane cyane mu bihe bikurikira:

①Ingufu nyinshi zikoresha laser zikoresha ingufu nyinshi: Zirinda ingaruka zo kuzura cyangwa ingaruka zitari zo ku murongo

②Amplifiers za fibre laser: Zigabanya ubwiyongere bwa ASE (Amplified Spontaneous Emission)

③Sisitemu za LIDAR na rangefinding: Zinoza uburyo bwo gupima no gusubiramo

④Laser zo kwa muganga: Zigenzura neza ingufu mu gihe cyo kuvurwa

5. Umwanzuro

Gukwirakwira kw'ikwirakwizwa ry'imashini bishobora kuba atari cyo kimenyetso kigaragara cyane cya module ya pompe, ariko ni ingenzi kugira ngo ikoreshwe neza mu buryo bwizewe sisitemu za laser zifite imikorere myiza. Uko ibisabwa ku bwiza bwa laser no kugumana umutekano bikomeza kwiyongera, abakora module za pompe bagomba kuvura"kugenzura uburinganire"nk'igikorwa cy'ingenzi—kunoza buri gihe guhitamo ibyuma bikoresha ikoranabuhanga, imiterere y'imiterere, n'ingamba z'ubushyuhe kugira ngo haboneke amasoko yizewe kandi ahoraho ya laser ku bikorwa biri imbere.

Urashaka kumenya uburyo twakoresha uburyo bwo kunoza uburyo bwo gukusanya umusaruro mu buryo bungana muri module zacu za pompe? Twandikire uyu munsi kugira ngo umenye byinshi ku bisubizo byacu n'ubufasha bwa tekiniki.
