Lub npe hu ua ib qho emitter yog qhov peb feem ntau hu ua "laser nti". Nws cov txheej txheem tsim khoom yog tib yam li cov khoom siv hluav taws xob semiconductor, uas dhau los ntawm cov txheej txheem xws li silicon wafer manufacturing, IC tsim, IC manufacturing, IC sealing thiab kuaj. Qhov kawg nti yog hu ua ib lub diode laser. Lub laser bar tuaj yeem suav tau tias yog ib qho laser bar tsim los ntawm ntau yam ib leeg semiconductor emitters ib sab, uas yog hu ua bar. Nyob rau hauv qhov tseeb, nws yog tsim los ntawm kev tsim ib tug series ntawm ib tug semiconductor laser emitters ntawm tib lub substrate, uas kuj hu ua ib tug linear array laser. Yooj yim to taub, ntau lub emitters tau teem rau hauv ib lub bar, thiab ib qho bar tuaj yeem muab faib ua ntau yam emitters.


Ib leeg laser emitter muaj tsuas yog ib qho luminous point, uas yog ib qho yooj yim rau fiber coupling. Yog li ntawd, nws yog feem ntau siv los ua lub twj tso kua mis ntawm fiber ntau laser (feem ntau nruab nrab thiab qis zog), uas tuaj yeem txo qhov kev sib nrig sib cuam tshuam ntawm thermal teebmeem, thiab yooj yim kho, tswj thiab hloov. Tsis tas li ntawd, lub zog tsav tsav nrog lub zog siab thiab qis tam sim no muaj cov qauv yooj yim thiab tus nqi qis; Lub laser bar muaj lub zog luminous ntau dua vim nws cov ntsiab lus luminous ntau, yog li nws feem ntau siv los ua lub twj tso kua mis lossis ncaj qha luminescence ntawm high-power fiber lasers thiab tag nrho cov khoom hauv lub xeev lasers. Nws kuj yog siv dav hauv kev kho mob, tub rog thiab lwm yam kev lag luam. Tam sim no, lub zog siab tshaj plaws ntawm ib lub raj laser hauv Suav teb tuaj yeem ncav cuag 20W, thaum lub laser bar tuaj yeem ua tiav 300W lossis siab dua lub zog tso zis.
