Kev kho tshiab thev naus laus zis tau ua cov lasers nkag mus rau ntau yam kev lag luam los ntawm cov cuab yeej tshwj xeeb. Laser diodes yog cov feem ntau siv cov tshuab laser thiab yog cov khoom siv hluav taws xob yooj yim. Tau 30 lub xyoo dhau los, qhov nruab nrab lub zog ntawm laser diodes tau nce ntau, thaum tus nqi nruab nrab rau ib watt tau poob txig. Raws li qhov tshwm sim, laser diodes hloov qee cov kev siv tshuab hluav taws xob tsis ntev thiab cov khoom siv hluav taws xob, thaum tseem ua kom cov khoos phis tawm tshiab. Cov ntawv thov kev loj hlob rau lub laser diodes suav nrog cov ntaub ntawv khaws cia, cov ntaub ntawv kev sib txuas lus, thiab kev kho qhov muag ntawm lub zog-lub xeev lasers. Rau hauv sib piv, cov ntaub ntawv uas ua thiab kho qhov muag tsoov yog cov piv txwv ntawm cov ceev ceev txoj kev loj hlob ntawm kev ua lag luam feem nyob rau hauv uas muaj ntau yam tawm daim ntaub ntawv mam li.
Lub zog tawm ntawm ib lub laser diode sib txawv ntawm milliwatts mus rau ntau tus watt. Lub zog muaj peev xwm tau nce los ntawm kev sib txuas ntawm ib qho emitter mus rau hauv lub laser diode bar thiab tus lej ntawm cov kav; ib tus qauv bar muaj qhov dav li ntawm 1 cm. Rau xyoo lawm, tuam txhab uas muag tau fiercely sib tw ua rau kom cov tso zis ntau zog ntawm diode tuav, thiab tau hais ib exponential kev loj hlob qauv. Txawm tias nyob rau hauv coj mus muag diode bar khoom, lub hwj chim ntawm txhua diode bar yog feem ntau tsawg tshaj li 200 watts ntawm 1 micron wavelength, lub R& D department ntawm laser raug tuam txhab uas muag tau pom qhov nruab nrab ntawm tas mus li yoj (CW). Lub hwj chim tshaj 1 kW / bar. Qhov nce nyob rau hauv diode bar hwj chim tau cov ntawv tshiab nyob rau hauv lub teb ntawm cov ntaub ntawv uas ua tau, tab sis ib txhia tawm daim ntaub ntawv yuav tsum nce laser tsis xws li wavelength stability thiab ntaus lub neej. Yog li ntawd, lub hwj chim kev sib tw yog tsis ib tug tseem ceeb tshaj plaws rau cov tuam txhab nyob rau hauv no ua lag luam. Txoj kev txhim kho txuas ntxiv ntawm diode laser thev naus laus zis yog xav txog qhov kev txhim kho ntawm infrared nqaj zoo rau precision engineering thiab kev tsim kho tshiab pom lub teeb lasers rau kev ua haujlwm hlau.
Nruam yoj (CW) laser diode bar hwj chim txoj kev loj hlob
Raws li cov ntaub ntawv sau thiab txheeb xyuas los ntawm IDTechEx, cov txheej txheem kev txhim kho ntawm lub laser diode bar tso tawm fais fab ntawm 1 micron infrared wavelength tau kawm, raws li pom hauv daim duab saum toj no. Qhov nce ntawm diode bar zog tau tsim txoj kev loj hlob ntawm kev ncaj qha diode lasers thiab ua cov ntawv thov tshiab hauv cov khoom ua tau. Txoj kev txhim kho txuas ntxiv ntawm diode laser thev naus laus zis yog xav txog qhov kev txhim kho ntawm infrared nqaj zoo rau precision engineering thiab kev tsim kho tshiab pom lub teeb lasers rau kev ua haujlwm hlau.
