Kev xaiv zoo tagnrholaser qhov chawTug: Emission semiconductor laser
1. Taw qhia
Semiconductor laserchips tau muab faib ua ntug emitting laser chips (EEL) thiab ntsug kab noj hniav nto emitting laser chips (VCSEL) raws li cov txheej txheem tsim khoom sib txawv ntawm cov resonators, thiab lawv cov qauv tshwj xeeb sib txawv tau pom hauv daim duab 1. Piv nrog cov kab noj hniav ntsug nto emitting laser, ntug emitting semiconductor laser technology kev loj hlob yog ntau mature, nrog ib tug dav wavelength ntau, siabelectro-opticalconversion efficiency, loj zog thiab lwm yam zoo, heev haum rau laser ua, kho qhov muag kev sib txuas lus thiab lwm yam teb. Tam sim no, ntug-emitting semiconductor lasers yog ib feem tseem ceeb ntawm kev lag luam optoelectronics, thiab lawv cov ntawv thov tau them rau kev lag luam, kev sib txuas lus, kev tshawb fawb, neeg siv khoom, tub rog thiab aerospace. Nrog rau txoj kev loj hlob thiab kev loj hlob ntawm technology, lub hwj chim, kev cia siab rau thiab lub zog conversion efficiency ntawm ntug-emitting semiconductor lasers tau zoo heev, thiab lawv daim ntawv thov kev cia siab yog ntau thiab ntau nws kim heev.
Tom ntej no, kuv yuav coj koj mus ntxiv txaus siab rau lub cim ntxim nyiam ntawm sab-emittingsemiconductor lasers.

2. Ua hauj lwm hauv paus ntsiab lus ntawm ntug emission semiconductorlaser
Cov qauv ntawm ntug-emitting semiconductor laser tuaj yeem muab faib ua peb ntu hauv qab no: semiconductor active cheeb tsam, twj tso kua mis thiab optical resonator. Sib txawv ntawm resonators ntawm ntsug kab noj hniav nto-emitting lasers (uas yog tsim los ntawm sab saum toj thiab hauv qab Bragg tsom iav), cov resonators nyob rau hauv ntug-emitting semiconductor laser li mas yog tsim los ntawm optical films ntawm ob sab. Cov qauv EEL cov qauv thiab cov qauv resonator tau pom nyob rau hauv daim duab 2. Lub photon nyob rau hauv lub ntug-emission semiconductor laser ntaus ntawv yog amplified los ntawm kev xaiv hom nyob rau hauv lub resonator, thiab lub laser yog tsim nyob rau hauv cov kev taw qhia parallel mus rau lub substrate nto. Ntug-emitting semiconductor laser li muaj ntau yam kev khiav hauj lwm wavelengths thiab tsim nyog rau ntau yam kev siv, yog li lawv dhau los ua ib qho zoo tshaj plaws laser qhov chaw.
Kev ntsuas kev ua tau zoo ntawm ntug-emitting semiconductor lasers kuj zoo ib yam nrog lwm cov semiconductor lasers, suav nrog: (1) laser lasing wavelength; (2) Qhov pib tam sim no Ith, uas yog, tam sim no ntawm lub laser diode pib tsim laser oscillation; (3) Ua haujlwm tam sim no Iop, uas yog, tsav tam sim no thaum lub laser diode ncav cuag lub zog tso zis, qhov ntsuas no yog siv rau kev tsim thiab hloov kho ntawm lub laser tsav Circuit Court; (4) Txoj kab nqes efficiency; (5) Vertical divergence Angle θ⊥; (6) Kab rov tav divergence Lub kaum sab xis θ∥; (7) Saib xyuas tam sim no Im, uas yog, tam sim no qhov loj me ntawm semiconductor laser nti ntawm lub zog tso zis.
3. Kev tshawb fawb kev nce qib ntawm GaAs thiab GaN raws ntug emitting semiconductor lasers
Lub semiconductor laser raws li GaAs semiconductor khoom yog ib qho ntawm cov paub tab tshaj plaws semiconductor laser technologies. Tam sim no, GAAS-raws li nyob ze-infrared band (760-1060 nm) ntug-emitting semiconductor lasers tau siv dav hauv kev lag luam. Raws li lub cim thib peb cov khoom siv semiconductor tom qab Si thiab GaAs, GaN tau muaj kev txhawj xeeb dav hauv kev tshawb fawb thiab kev lag luam vim nws lub cev zoo heev thiab tshuaj lom neeg. Nrog rau txoj kev loj hlob ntawm GAN-raws li optoelectronic li thiab kev siv zog ntawm cov kws tshawb fawb, GAN-raws li lub teeb-emitting diodes thiab ntug-emitting lasers tau industrialized.
