Intangiriro kuri vertical cavity surface isohorasemiconductor laser(VCSEL)
Lazeri zo hanze ziva hanze zasohotse hagati yimyaka ya za 90 kugirango zitsinde ikibazo cyingenzi cyugarije iterambere rya lazeri gakondo ya semiconductor: uburyo bwo kubyara ingufu za lazeri zifite ingufu nyinshi zifite ubuziranenge bwo hejuru muburyo bwo guhinduranya ibintu.
Vertical external cavity surface-isohora laseri (Vecsels), izwi kandi nkasemiconductor disiki(SDL), ni abanyamuryango bashya mumuryango wa laser. Irashobora gushushanya uburebure bwimyuka ihumanya ihindura ibintu hamwe nubunini bwa kwantani neza muri semiconductor yunguka hagati, kandi igahuzwa ninshuro ebyiri inshuro ebyiri zishobora gukwirakwiza intera ndende kuva ultraviolet ikagera kuri infragre kure, ikagera kumasoko menshi mugihe ikomeje gutandukana. Inguni izenguruka ya laser beam. Laser resonator igizwe na DBR yo hepfo yuburyo bwunguka chip hamwe nindorerwamo isohoka yo hanze. Iyi miterere idasanzwe yo hanze ya resonator ituma ibintu bya optique byinjizwa mumurwango kubikorwa nko gukuba inshuro ebyiri, gutandukanya inshuro, no gufunga uburyo, bigatuma VECSEL iba nzizaInkomokokuri porogaramu kuva kuri biofotonike, spectroscopy,imiti ya laser, na laser projection.
Rezonator ya VC-yubuso isohora semiconductor laser ni perpendicular ku ndege aho akarere gakorera gaherereye, kandi itara ryayo risohoka ni perpendicular ku ndege y'akarere gakorera, nkuko bigaragara ku gishushanyo.VCSEL ifite ibyiza byihariye, nka bito ingano, inshuro nyinshi, ubwiza bwibiti byiza, ubunini bunini bwangiritse hejuru yurwego, hamwe nuburyo bworoshye bwo gukora. Irerekana imikorere myiza mubikorwa bya laser yerekana, itumanaho ryiza hamwe nisaha nziza. Nyamara, VCsels ntishobora kubona lazeri zifite ingufu nyinshi hejuru yurwego rwa watt, ntabwo rero zishobora gukoreshwa mumirima ifite ingufu nyinshi.

Laser resonator ya VCSEL igizwe na ecran ya Bragg yagabanijwe (DBR) igizwe na epitaxial etaxial stratifike yibikoresho bya semiconductor kumpande zombi zo hejuru no hepfo yakarere gakorera, bitandukanye cyane nalaserresonator igizwe nindege ya clavage muri EEL. Icyerekezo cya optique resonator ya VCSEL ni perpendicular kuri chip hejuru, ibisohoka bya laser nabyo ni perpendicular hejuru ya chip, kandi kugaragariza impande zombi za DBR birarenze cyane iby'indege ya EEL ikemura.
Uburebure bwa laser resonator ya VCSEL mubusanzwe ni microne nkeya, ikaba ari nto cyane ugereranije na milimetero resonator ya EEL, kandi inyungu imwe yabonetse kubwo guhungabana kwa optique mumurwango ni muke. Nubwo uburyo bwibanze bwo guhindura ibintu bushobora kugerwaho, imbaraga zisohoka zishobora kugera kuri miliwatt nyinshi. Umwirondoro wambukiranya ibice bya VCSEL bisohora laser beam ni umuzenguruko, kandi Inguni yo gutandukana ni ntoya cyane kuruta iy'urumuri rusohora urumuri. Kugirango ugere ku mbaraga nyinshi za VCSEL, birakenewe kongera akarere ka luminous kugirango utange inyungu nyinshi, kandi kwiyongera kwakarere ka luminous bizatuma lazeri isohoka ihinduka uburyo bwinshi. Muri icyo gihe, biragoye kugera ku gutera inshinge imwe mu karere kanini kameze neza, kandi inshinge zidahwanye nazo zizongera ubukana bw’imyanda.Muri make, VCSEL irashobora gusohora uburyo bwibanze buzenguruka ahantu hifashishijwe igishushanyo mbonera, ariko imbaraga zisohoka ni nke mugihe ibisohoka ari uburyo bumwe.Nuko rero, VCsels nyinshi zinjizwa muburyo bwo gusohoka.
