Laser diodes thiab VCELS yog semiconductor lasers, qhov nyuaj daim ntawv ntawm Khoom State Lasers.Laser diodes yog feem ntau hu ua ntug emitting diodes laser vim hais tias cov laser lub teeb yog tawm txim liab los ntawm lub ntug ntawm lub substrate.The teeb emitting cheeb tsam ntawm lub laser diode yog feem ntau hu ua emitter.Qhov emitter qhov loj me thiab qhov ntau ntawm cov emitters txiav txim siab tsim tawm lub zog thiab cov nqaj zoo ntawm lub laser diode.
Cov Fabry Perot Diode Laserswith ib zaug xwb emission cheeb tsam (emitter) yog feem ntau hu ua laser diode chips, thaum ib tug linear array ntawm emitters yog hu ua laser diode bars.Laser diode tuav feem ntau siv multimode emitters, tus xov tooj ntawm emitters ib substrate yuav sib txawv ntawm 5 emitters 100 emitters.
VCSELs (Ntsig Cavity Ntev Emitting Laser) emit lub teeb sib tshuam mus rau qhov muaj chaw saum npoo tsis pom zoo ib yam li ntug emitting laser diodes. VCSELs muaj ib tug uniform spatial illumination nyob rau hauv ib tug yeej illumination qauv nrog tsawg speckle.
