Taw qhia rau Edge Emitting Laser (EEL)
Yuav kom tau txais high-power semiconductor laser tso zis, lub tshuab tam sim no yog siv ntug emission qauv. Lub resonator ntawm ntug-emitting semiconductor laser yog tsim los ntawm lub ntuj dissociation nto ntawm lub semiconductor siv lead ua, thiab cov zis beam yog emitted los ntawm pem hauv ntej kawg ntawm lub laser.Lub ntug-emission hom semiconductor laser yuav ua tau siab zog tso zis, tab sis nws cov zis qhov chaw yog elliptical, lub beam zoo yog tsis zoo, thiab lub beam zoo li yuav tsum tau hloov kho.
Cov duab hauv qab no qhia txog cov qauv ntawm ntug-emitting semiconductor laser. Optical kab noj hniav ntawm EEL yog thaum uas tig mus rau saum npoo ntawm lub semiconductor nti thiab emits laser nyob rau ntawm ntug ntawm lub semiconductor nti, uas muaj peev xwm paub lub laser tso zis nrog siab zog, siab ceev thiab tsis muaj suab nrov. Txawm li cas los xij, lub laser beam tso zis los ntawm EEL feem ntau muaj asymmetric beam cross section thiab loj angular divergence, thiab cov coupling efficiency nrog fiber ntau los yog lwm yam optical Cheebtsam yog tsawg.

Qhov nce ntawm EEL tso zis hluav taws xob yog txwv los ntawm cov khoom siv hluav taws xob pov tseg hauv thaj chaw nquag thiab kho qhov muag ntawm qhov chaw semiconductor. Los ntawm kev ua kom lub waveguide cheeb tsam kom txo tau cov khib nyiab thaum tshav kub kub nyob rau hauv lub active cheeb tsam los txhim kho lub tshav kub dissipation, ua kom lub teeb tso zis cheeb tsam kom txo tau lub optical zog ceev ntawm lub beam kom tsis txhob kho qhov muag puas, lub tso zis hwj chim mus txog rau ob peb puas milliwatts yuav ua tau tiav nyob rau hauv ib tug transverse hom waveguide qauv.
Rau 100mm waveguide, ib qho ntug-emitting laser tuaj yeem ua tiav kaum tawm watts ntawm cov zis hluav taws xob, tab sis lub sij hawm no lub waveguide yog ntau hom ntawm lub dav hlau ntawm lub nti, thiab cov zis beam nam piv kuj nce mus txog 100: 1, yuav tsum tau ib tug complex beam shaping system.
Nyob rau hauv qhov tseeb hais tias tsis muaj ib tug tshiab breakthrough nyob rau hauv cov khoom siv technology thiab epitaxial kev loj hlob technology, lub ntsiab txoj kev los txhim kho lub zog tso zis ntawm ib tug semiconductor laser nti yog ua kom lub strip dav ntawm lub nti luminous cheeb tsam. Txawm li cas los xij, ua kom lub sawb dav siab dhau lawm yog ib qho yooj yim los tsim transverse high-order hom oscillation thiab filamentlike oscillation, uas yuav txo tau qhov sib xws ntawm lub teeb pom kev zoo, thiab cov zis hluav taws xob tsis nce proportionally nrog lub sawb dav, yog li cov zis hluav taws xob ntawm ib nti tsis tshua muaj kev txwv. Txhawm rau txhim kho lub zog tso zis ntau, array thev naus laus zis los ua. Cov thev naus laus zis sib xyaw ua ke ntau lub laser rau ntawm tib lub substrate, kom txhua lub teeb emitting unit yog lined li ib-seem array nyob rau hauv qeeb axis kev taw qhia, tsuav yog cov optical cais tshuab siv los cais txhua lub teeb emitting unit nyob rau hauv lub array, thiaj li hais tias lawv tsis cuam tshuam nrog txhua lwm yam, tsim ib tug multi-aperture lub zog ntawm tag nrho cov nti tso tawm, koj muaj peev xwm ua kom ib tug ntau-aperture lub hwj chim lasing. emitting units. Qhov no semiconductor laser nti yog ib tug semiconductor laser array (LDA) nti, kuj hu ua semiconductor laser bar.
