Laser Diode Bar: Simba Guru Riri Kuseri Kwemashandisirwo ELaser Ane Simba Rakawanda

Sezvo tekinoroji yelaser ichiramba ichichinja, mhando dzemanyuko elaser dziri kuramba dzichisiyana-siyana. Pakati padzo, laser diode bar inoonekwa nekuburitsa kwayo simba rakawanda, chimiro chayo chidiki, uye manejimendi yekupisa yakanakisa, zvichiita kuti ive chinhu chakakosha muminda yakaita sekugadzirisa maindasitiri, runako rwekurapa, manyuko epombi, uye kutsvagisa kwesainzi.

1. Chii chinonzi Laser Diode Bar?

Bhawa re laser diode, rinozivikanwawo se laser diode array, mudziyo we laser une simba guru unoumbwa nekubatanidza mayuniti akawanda anoburitsa laser pane imwe substrate yakafanana. Kazhinji, unit yega yega inoburitsa emission inosvika 100 micrometers yakafara, nepo upamhi hwese hwebhawa hunogona kubva pamamirimita akati wandei kusvika pamasendimita. Nekuti mayuniti akawanda e laser akarongwa padivi nepadivi, mabara e laser diode anogona kupa simba risingaperi kana kuti rinoputika kubva pamakumi ewatts kusvika pamusoro pe kilowatt.

2. Zvinhu Zvikuru

① Simba Rakawanda

Mabhawa eLaser diode anobatanidza maemitter akawanda munzvimbo diki kuti ape simba rakawanda, zvichiita kuti akwanise kushandiswa zvinoda simba rakawanda.

② Kutarisira Kupisa Kwakanaka Kwazvo

Chimiro chebhawa chinoenderana nehunyanzvi hwakasiyana-siyana hwekurongedza, hwakadai seAuSn (gold-tin), all-indium, uye hybrid packaging, izvo zvinowedzera kupisa, kuwedzera hupenyu hwemuchina, uye kuona kuti unoshanda kwenguva refu.

③ Mawavelength Anogona Kugadziriswa

Zvichienderana nekushandiswa, mabara e-laser diode anogona kugadzirwa kuti ashandiswe nenzira dzakasiyana dzemarefu ekushanda, akadai se808 nm, 915 nm, 940 nm, uye 976 nm. Kugadzirisa marefu emagetsi kwakakosha kunowanikwawo kuti kugutse zvinodiwa nezvinhu zvakasiyana-siyana uye masisitimu.

④ Kuumba Matanda Anochinjika

Kunyangwe hunhu hwemwenje we laser diode bars hunowanzo kuve hwakaderera pane hwe single-mode lasers, zvikamu zve optical zvakaita se lens arrays, fiber coupling, uye micro-lens systems zvinogona kushandiswa ku corlimate kana kutarisisa mwenje, zvichiwedzera kubatanidzwa uye kuchinjika mumashandisirwo esystem.

3. Minda Yekushandisa

① Kugadzira Maindasitiri

Mabhawa e laser diode anoshandiswa mukunamira purasitiki, kurapa kupisa kwesimbi, kuchenesa ne laser, uye kuisa mamaki, anopa chiyero chakanaka chemutengo-kushanda mumasisitimu anoda masosi e laser ane simba guru.

② Zvekurapa uye Runako

Semuenzaniso, 808 nm laser diode bars dzinoshandiswa zvakanyanya mumidziyo yekubvisa bvudzi nelaser. Dzinopa simba rakawanda uye kudzika kuri pakati nepakati, dzichiparadza mafollicle ebvudzi pasina kukuvadza nyama yakakomberedza.

③ Matsime ePombi eFiber Lasers

Mumasystem elaser ane simba guru, ma laser diode bars anowanzo shandiswa semapombi ekumutsa mafiber ane Yb kana Er, achiita basa rinokosha mukuvaka masystem elaser ane simba guru.

④ Tsvagiridzo yeSainzi neDziviriro

Mabhawa eLaser diode anoshandiswawo zvakanyanya mumatekinoroji epamusoro akadai sekuyedza kwefizikisi ine simba rakawanda, LiDAR, uye kutaurirana kwelaser, nekuda kwesimba rawo rekugadzira uye hunhu hwawo hunogona kugadziriswa.

Sezvo zvinodiwa pakushanda kwemasisitimu elaser zvichiramba zvichikwira, mabara elaser diode ari kuchinja achienda kusimba rakakwirira, kuvimbika kukuru, zvinhu zvidiki zvechimiro, uye mitengo yakaderera. Sechikamu chakakosha mumasisitimu ekushandisa laser, mabara elaser diode ari kushandiswa zvakanyanya munzvimbo dzetekinoroji yepamusoro. Nekufambira mberi kwetekinoroji kuri kuramba kuchienderera mberi uye cheni yeindasitiri iri kukura, mabara elaser diode anotarisirwa kunakidzwa netariro yakakura yemusika uye kutora basa rakakosha mune ramangwana.
