Mu rwego rwimbaraga-zohejuru, laser bar nibintu byingenzi byingenzi. Ntabwo bakora gusa nkibice byibanze byingufu zitanga ingufu, ahubwo binagaragaza neza no guhuza ibikorwa bya kijyambere optoelectronic engineering-kubashakira izina: "moteri" ya sisitemu ya laser. Ariko mubyukuri ni ubuhe buryo bw'imiterere ya laser, kandi nigute itanga mirongo icumi cyangwa amagana ya watts y'ibisohoka bivuye kuri milimetero nkeya gusa? Iyi ngingo irasobanura ubwubatsi bwimbere namabanga yubuhanga inyuma ya laser bar.
1. Ikibari cya Laser ni iki?
Laser bar nigikoresho kinini gisohora imbaraga kigizwe na chipi ya laser diode nyinshi ikurikiranye kuri substrate imwe. Mugihe ihame ryakazi ryayo risa nkiryo lazeri imwe ya semiconductor, umurongo wa laser ukoresha imiterere-emitter nyinshi kugirango ugere kumashanyarazi yo hejuru kandi arikintu cyoroshye.
Utubari twa Laser dukoreshwa cyane mubice byinganda, ubuvuzi, siyanse, n’ingabo, haba nkisoko ya lazeri itaziguye cyangwa nkisoko ya pompe ya fibre fibre na lazeri ikomeye.
2. Imiterere yuburyo bwa Laser Bar
Imiterere yimbere yumurongo wa laser igena neza imikorere yayo. Igizwe ahanini nibice byingenzi bikurikira:
①Emitters Array
Utubari twa Laser mubusanzwe tugizwe na 10 kugeza 100 zohereza (laser cavities) zitondekanye kuruhande. Buri emitter igera kuri 50-150μm ubugari kandi ikora nkakarere kigenga kunguka, kugaragaramo PN ihuza, cavant resonant, hamwe nuburyo bwo kuzunguruka kugirango bibyare kandi bisohore urumuri rwa laser. Mugihe ibyasohotse byose bisangiye substrate imwe, mubisanzwe bitwarwa namashanyarazi muburyo bubangikanye cyangwa na zone.
②Imiterere ya Semiconductor
Hagati yumurongo wa laser ni agace kamwe ka semiconductor, harimo:
- P-ubwoko na N ubwoko bwa epitaxial (gukora PN ihuza)
- Igikorwa gifatika (urugero, imiterere ya kwantum), ibyuka bihumanya
- Waveguide layer, yemeza uburyo bwo kugenzura muburyo bwerekeranye no guhagarikwa
- Kwirata ibyerekana cyangwa HR / AR bitwikiriye, byongera icyerekezo cya laser
③Inzira yo gucunga no gutunganya ubushyuhe
Ibisohoka bihingwa kuri monolithic semiconductor substrate (muri rusange GaAs). Kugira ngo ubushyuhe bugabanuke neza, akabari ka laser kagurishwa hejuru yumuriro mwinshi nkumuringa, W-Cu alloy, cyangwa diyama ya CVD, hanyuma ugahuzwa nubushyuhe hamwe na sisitemu yo gukonjesha.
④Sisitemu yoherezwa mu kirere hamwe na sisitemu yo gukusanya
Bitewe n’imfuruka nini yo gutandukanya ibiti bisohotse, utubari twa laser dusanzwe dufite ibikoresho bya micro-lens (FAC / SAC) kugirango byegeranye kandi bibeho. Kuri porogaramu zimwe, optique yinyongera-nka lisansi ya silindrike cyangwa prism-Byakoreshejwe Kugenzura kure-Umwanya Gutandukana hamwe nubuziranenge bwibiti.
3. Ibintu by'ingenzi byubaka bigira ingaruka kumikorere
Imiterere yumurongo wa laser igira uruhare runini muguhitamo ituze, imikorere, nubuzima bwa serivisi. Ibintu byinshi by'ingenzi birimo:
①Igishushanyo mbonera cyo gucunga ubushyuhe
Utubari twa Laser tugaragaza imbaraga nyinshi nubushyuhe bwinshi. Kurwanya ubushyuhe buke ni ngombwa, bigerwaho binyuze mu kugurisha AuSn cyangwa guhuza indium, hamwe no gukonjesha microchannel kugirango ubushyuhe bumwe.
②Gushiraho ibiti no guhuza
Abasohoka benshi bakunze guhura nubusabane bubi hamwe no kudahuza umurongo. Igishushanyo mbonera cyerekana neza no guhuza ni ngombwa mu kuzamura ubuziranenge bwa kure.
③Kugenzura Stress no Kwizerwa
Kudahuza ibikoresho muri coefficient yo kwagura ubushyuhe birashobora gutuma umuntu arwana cyangwa microcrack. Gupakira bigomba kuba byateguwe kugirango bigabanye imihangayiko iringaniye kandi irinde gusiganwa ku magare yumuriro nta kwangirika.
4. Ibizaza muri Laser Bar Igishushanyo
Nkuko ibyifuzo byimbaraga zisumba izindi, ubunini buto, hamwe nubwizerwe bugenda bwiyongera, imiterere ya laser bar ikomeza guhinduka. Icyerekezo cyingenzi cyiterambere kirimo:
①Kwaguka k'umuraba: Kugera kuri 1.5μm na bande yo hagati
②Miniaturisation: Gushoboza gukoresha ibikoresho byoroheje hamwe na module ihuriweho cyane
③Gupakira neza: Kwinjiza ibyuma byubushyuhe hamwe na sisitemu yo gutanga ibitekerezo
④Ubucucike Bwinshi: Gutondekanya imirongo kugirango ugere kuri kilowatt-urwego rusohoka mumagambo magufi
5. Umwanzuro
Nka“umutima”ya sisitemu ikomeye ya laser sisitemu, igishushanyo mbonera cyibikoresho bya laser bigira ingaruka itaziguye, optique, amashanyarazi, nubushyuhe bwa sisitemu rusange. Kwinjiza ibyuka byinshi bisohora mumiterere ya milimetero imwe gusa ntabwo byerekana gusa ibikoresho byateye imbere hamwe nubuhanga bwo guhimba, ariko kandi byerekana urwego rwo hejuru rwo kwishyira hamwe muri iki gihe'Inganda.
Urebye imbere, mugihe icyifuzo gikenewe, cyizewe cya laser gikomeje kwiyongera, udushya mumiterere ya laser bar tuzakomeza kuba umushoferi wingenzi mugutezimbere inganda za laser.
Niba ari wowe're gushakisha inkunga yinzobere mugupakira laser bar, gucunga ubushyuhe, cyangwa guhitamo ibicuruzwa, wumve neza. Twebwe're hano kugirango utange ibisubizo byihariye kugirango uhuze ibyifuzo byawe byihariye.
