1. Dab tsi yog qhov zoo ntawm optical fiber txuas txuas tawm cov khoom siv semiconductor laser?
Semiconductor laser lub teeb emitting tsev ncaj qha mus rau cov qhov tso zis ntawm ib tug laser beam rau asymmetric elliptical Gaussian beam, lub divergence lub loj, lub teeb qhov chaw sis tsis ncaj, nyob rau hauv ib co daim ntawv thov chaw, yuav tsum tau yas thiab flare homogenization treatment.There yog ob lub ntsiab txoj kev uas feem ntau siv yas: yas kho qhov muag teeb thiab yas kho qhov muag fiber ntau txuas.Pure yas kho qhov muag kab teeb tsa tau tuaj yeem nrawm mus rau hauv kev sib dhos tab sis lub teeb sib npaug tsis zoo, thiab yoog tau siv.Qhov kev sib txuas ntawm cov hluav taws xob optical fiber ntau, qhov kho qhov muag fiber ntau rau cov khoom sib txig rau cov kev sib tshooj muaj thiab zoo dua kev sib luag. , beam zoo kev txhim kho; thiab fiber coupling yog qhov tseem ceeb txhais tau tias kom paub laser saj zawg zog kis tau tus mob, semiconductor laser yog heev enhanced cov yooj thiab operability, siv nyob rau hauv qhov chaw xws li kev kho mob, cov zauv ntau saj zawg zog thiab yooj yim.
Brandnew ywm rau kho qhov muag fiber coupling, mas muab fiber ua ke laser diode.
2.Second, dab tsi yog raws tib lub vuam txuas txuas txoj kev?
Brandnew yog muab los ntawm laser yog raws li nyob rau hauv lub kho qhov muag fiber coupling ib cov yeeb nkab, cov khoom muaj xws li ib cov yeeb nkab coupling series, ntau tshaj ib cov yeeb nkab coupling thiab kho qhov muag fiber nras module series.Single yeeb nkab coupling txoj kev yog ib LD yeeb nkab tub ntxhais teeb coupling rau tus kho qhov muag fiber, tom qab ntau lawm qhwv ib tug tej yam tso zis ntau zog ntawm semiconductor laser.Single yeeb nkab coupling series ntawm 405 nm rau 976 nm wavelength, lub hwj chim 2 MW mus rau 10 w.Single raj fiber coupling series ntau yog siv ib cov yeeb nkab coupling technology, yuav muab ob peb los yog txawm dozens ntawm LD beam yog pom tau hais los tsim nyog tsim ntawm lub teeb kev, yog li ua ke rau hauv lub fiber, lub wavelengths ntawm 450 nm rau 976 nm, 1.6 W rau 200 W hwj chim yog achieved.Optical fiber nras module yog ntau tshaj fiber ua ke laser module ntawm optical fiber nras tom qab kev lag luam kev sib koom ua ke sib xyaw ua ke txuas rau hauv cov hluav taws xob tso tawm dua, nqaj splitter tuaj yeem los ntawm 450 nm txog 1550 nm wavelength, lub zog yog 300 w.After dav dav zog loj laser adopts ob txoj kev.
3.Ntawm cov roj carbon fiber ntau ntawm cov nqaj yog dab tsi?
Tej yam yooj yim hais lus, los ntawm cov finer tso zis ntawm beam yog feem ntau ib tug tej yam divergence lub ntawm lub yeej teeb spot.Specific beam loj yog txuam nrog kho qhov muag fiber tub ntxhais txoj kab uas hla, qhov loj ntawm lub divergence lub yog txiav txim los ntawm tus kho qhov muag fiber txog zauv aperture.Commonly siv kho qhov muag fiber tau muab faib ua ib hom thiab multimode, ib-hom ntxhais taub los ntawm 2.9 mu mu m mus rau 9 m, multimode tub ntxhais taub los ntawm 50 microns rau 400 microns, cov lej muaj ntau ntawm 0.15 0.22 NA NA thiab general.Numerical aperture yog hais txog beam အဖြစ်အပျက် Qhov siab ntawm tag nrho cov kev xav txog nyob rau hauv optical fiber kis ntawm sine tus nqi, tuaj yeem tsuas yog xav tias divergence Lub kaum ntse ntse ntawm laser tawm cov fiber ntau, 0.22 NA sawv cev rau divergent Lub kaum ntse ntse yog 12.5 ° Lub Kaum Ib Hlis (ib nrab), 0.15 NA sawv cev divergent Lub kaum hli txog 8 °
