Umugozi wa Diode ya Laser: Imbaraga z'ingenzi zituma habaho porogaramu za Laser zifite imbaraga nyinshi

Uko ikoranabuhanga rya laser rikomeza gutera imbere, ubwoko bw'amasoko ya laser buri kugenda butandukana cyane. Muri byo, umugozi wa laser diode ugaragara cyane kubera imbaraga zawo nyinshi, imiterere mito, no gucunga neza ubushyuhe, bigatuma uba ingenzi mu nzego nko gutunganya inganda, ubwiza bw'ubuvuzi, amasoko ya pompe, n'ubushakashatsi bwa siyansi.

1. Akabari ka Laser Diode ni iki?

Akabari ka laser diode, kazwi kandi nka laser diode array, ni igikoresho cya laser cya semiconductor gifite imbaraga nyinshi gikozwe no guhuza utwuma twinshi dusohora laser ku gice kimwe gisanzwe. Ubusanzwe, buri gice gisohora gifite ubugari bwa mikorometero 100, mu gihe ubugari bwose bw'akabari bushobora kuva kuri milimetero nyinshi kugeza kuri santimetero. Kubera ko utwuma twinshi twa laser dutondetse iruhande, utwuma twa laser diode dushobora gutanga imbaraga zihoraho cyangwa zihindagurika kuva kuri wati icumi kugeza kuri kilowati irenga.

2. Ibiranga by'ingenzi

① Ubucucike bw'ingufu nyinshi

Utubati twa diode ya laser duhuza imiyoboro myinshi mu mwanya muto kugira ngo dutange imbaraga nyinshi cyane, bigatuma tuba beza cyane ku bikorwa bisaba ingufu nyinshi.

② Gucunga neza ubushyuhe

Imiterere y'urubaho ijyanye n'ikoranabuhanga ritandukanye ryo gupakira, nka AuSn (gold-tin), all-indium, na hybrid packing, byongerera ubushyuhe ihindagurika, byongera igihe cyo kubaho kw'igikoresho, kandi bigatuma gikora neza igihe kirekire.

③ Uburebure bw'amabara bushobora guhindurwa

Bitewe n'uburyo ikoreshwa, utubari twa laser diode dushobora gukorerwa uburebure butandukanye bw'uburebure, nka 808 nm, 915 nm, 940 nm, na 976 nm. Uburyo bwihariye bwo guhindura uburebure bw'uburebure burahari kugira ngo buhuze n'ibikenewe byihariye by'ibikoresho na sisitemu zitandukanye.

④ Uburyo bwo gushushanya imirasire ihindagurika

Nubwo ubwiza bw'imirasire ya laser diode muri rusange buri hasi ugereranyije n'iya single-mode lasers, ibice by'urumuri nka lens arrays, fibre coupling, na micro-lens systems bishobora gukoreshwa mu guhuza cyangwa kwibanda ku murasire, bikongera uburyo bwo guhuza no koroshya ikoreshwa rya sisitemu.

3. Ahantu ho Gukoresha Porogaramu

① Inganda zikora

Uduti twa laser diode dukoreshwa mu gusudira pulasitiki, gutunganya ubushyuhe bw'icyuma, gusukura no gushyiraho ikimenyetso muri laser, dutanga igipimo cyiza cy'ikiguzi n'imikorere muri sisitemu zikenera amasoko ya laser afite ingufu nyinshi.

② Ubuvuzi n'Ubwiza

Urugero, utubari twa laser diode twa 808 nm dukoreshwa cyane mu bikoresho byo gukuraho umusatsi bya laser. Bitanga imbaraga nyinshi n'ubujyakuzimu buri hagati, bigasenya neza uduce tw'umusatsi tutibagiwe kwangiza ingirangingo ziwukikije.

③ Isoko rya pompe za fibre lasers

Muri sisitemu za laser zifite ingufu nyinshi, utubari twa laser diode dukunze gukoreshwa nk'isoko y'ipompo kugira ngo dukurure insinga za Yb-doped cyangwa Er-doped, bigira uruhare runini mu kubaka sisitemu za laser zifite imbaraga nyinshi.

④ Ubushakashatsi mu bya siyansi n'ubwubatsi

Utubati twa diode ya laser dukoreshwa cyane mu ikoranabuhanga rigezweho nko mu bushakashatsi bwa fiziki bukoresha ingufu nyinshi, LiDAR, no mu itumanaho rya laser, bitewe n'umusaruro wabyo uhoraho n'imiterere yabyo ishoboka.

Uko ibisabwa mu mikorere ya sisitemu ya laser bikomeza kwiyongera, utubari twa diode ya laser turimo guhinduka tugana ku mbaraga nyinshi, kwizerwa kurushaho, ibintu bito, no kugabanuka kw'ibiciro. Nk'igice cy'ingenzi muri sisitemu yo gukoresha laser, utubari twa diode ya laser turimo gukoreshwa cyane mu nzego zigezweho z'ikoranabuhanga. Bitewe n'iterambere rikomeje mu ikoranabuhanga n'uruhererekane rw'inganda rugenda rukura, utubari twa diode ya laser twitezweho kugira amahirwe menshi ku isoko no kugira uruhare runini mu gihe kizaza.
