Kev siv tshuab fiber ntau txhim kho lub zog thiab qhov ci ntawm cov laser semiconductor xiav

Kev siv tshuab fiber ntau ua rau lub zog thiab qhov ci ntsa iab ntawmlaser semiconductor xiav

Kev tsim cov beam siv tib lub wavelength lossis ze ntawm qhovlaserchav tsev yog lub hauv paus ntawm ntau lub teeb laser ua ke ntawm ntau lub wavelengths sib txawv. Ntawm lawv, qhov chaw sib txuas ntawm lub teeb yog los sib sau ua ke ntau lub teeb laser hauv qhov chaw kom nce lub zog, tab sis yuav ua rau lub teeb zoo txo ​​qis. Los ntawm kev siv cov yam ntxwv linear polarization ntawmlaser semiconductor, lub zog ntawm ob lub teeb uas nws qhov kev co yog perpendicular rau ib leeg tuaj yeem nce ntxiv ze li ntawm ob npaug, thaum lub teeb zoo tseem tsis hloov pauv. Fiber bundler yog lub cuab yeej fiber npaj raws li Taper Fused Fiber Bundle (TFB). Nws yog los strip ib pob ntawm optical fiber txheej txheej, thiab tom qab ntawd npaj ua ke hauv ib txoj kev, cua sov ntawm qhov kub siab kom yaj nws, thaum ncab cov optical fiber bundle hauv qhov kev taw qhia rov qab, qhov chaw cua sov optical fiber yaj rau hauv ib lub fused cone optical fiber bundle. Tom qab txiav tawm lub cone duav, fuse lub cone tso zis kawg nrog cov zis fiber. Fiber bunching technology tuaj yeem ua ke ntau tus kheej fiber bundles rau hauv ib lub loj-txoj kab uas hla bundle, yog li ua tiav cov khoom siv hluav taws xob optical siab dua. Daim duab 1 yog daim duab schematic ntawmlaser xiavkev siv tshuab fiber.

Cov txheej txheem sib xyaw ua ke ntawm cov teeb pom kev zoo siv ib lub khoom tawg ua ke los sib xyaw ua ke ntau lub teeb laser nrog cov wavelength intervals qis dua 0.1 nm tib lub sijhawm. Ntau lub teeb laser ntawm cov wavelengths sib txawv raug cuam tshuam rau ntawm lub teeb dispersive ntawm ntau lub kaum sab xis, sib tshooj ntawm lub teeb, thiab tom qab ntawd diffract thiab tso tawm hauv tib qho kev taw qhia raws li kev ua ntawm kev sib xyaw, yog li cov teeb laser sib xyaw ua ke sib tshooj hauv thaj chaw ze thiab thaj chaw deb, lub zog sib npaug rau qhov sib sau ua ke ntawm cov teeb unit, thiab qhov zoo ntawm lub teeb yog sib xws. Yuav kom paub txog kev sib xyaw ua ke ntawm cov teeb spectral nqaim, lub diffraction grating nrog kev sib xyaw ua ke muaj zog feem ntau yog siv ua lub teeb sib xyaw ua ke, lossis lub grating nto ua ke nrog hom kev tawm tswv yim sab nraud, tsis muaj kev tswj hwm ywj pheej ntawm cov spectrum laser unit, txo qhov nyuaj thiab tus nqi.

Cov laser xiav thiab nws cov teeb pom kev sib xyaw nrog infrared laser yog siv dav hauv kev vuam hlau tsis yog ferrous thiab kev tsim khoom ntxiv, txhim kho kev hloov pauv hluav taws xob thiab kev ruaj khov ntawm cov txheej txheem tsim khoom. Tus nqi nqus ntawm cov laser xiav rau cov hlau tsis yog ferrous tau nce ntau zaus txog kaum npaug ntau dua li ntawm cov lasers ze-infrared wavelength, thiab nws kuj txhim kho titanium, nickel, hlau thiab lwm yam hlau rau qee qhov. Cov lasers xiav muaj zog siab yuav ua rau kev hloov pauv ntawm kev tsim khoom laser, thiab kev txhim kho qhov ci ntsa iab thiab txo cov nqi yog qhov kev txhim kho yav tom ntej. Kev tsim khoom ntxiv, cladding thiab vuam ntawm cov hlau tsis yog ferrous yuav siv dav dua.

Nyob rau theem ntawm qhov kaj xiav qis thiab tus nqi siab, qhov chaw sib xyaw ua ke ntawm laser xiav thiab laser ze-infrared tuaj yeem txhim kho qhov kev hloov pauv hluav taws xob ntawm cov chaw teeb pom kev zoo uas twb muaj lawm thiab kev ruaj khov ntawm cov txheej txheem tsim khoom raws li qhov kev tswj hwm tus nqi. Nws yog qhov tseem ceeb heev rau kev tsim cov thev naus laus zis sib xyaw ua ke spectrum beam, daws cov teeb meem engineering, thiab sib xyaw ua ke cov thev naus laus zis laser siab ci kom paub txog kilowatt siab ci xiav semiconductor laser qhov chaw, thiab tshawb nrhiav cov thev naus laus zis sib xyaw ua ke beam tshiab. Nrog rau kev nce ntawm lub zog laser thiab qhov kaj, txawm tias yog qhov chaw teeb pom kev ncaj qha lossis tsis ncaj qha, laser xiav yuav tseem ceeb hauv kev tiv thaiv lub tebchaws thiab kev lag luam.
