Brewster Windows popanda Reflection zotayika za P-Polarization
Mawindo a Brewster nthawi zambiri amagwiritsidwa ntchito ngati polarizers mkati mwa mitsempha ya laser. Ikayikidwa pa Brewster's angle (55 ° 32' pa 633 nm), gawo la P-polarized la kuwala lidzadutsa pawindo popanda kutayika, pamene gawo la S-polarized gawo lidzawonetsedwa pawindo la Brewster. Mukagwiritsidwa ntchito muzitsulo za laser, zenera la Brewster limakhala ngati polarizer.
Mbali ya Brewster imaperekedwa ndi
pansi (θB= nt/ni
θBndi ngodya ya Brewster
nindi index of refraction of the incident medium, which is 1.0003 for air
ntndi index of refraction of transmitting medium, yomwe ndi 1.45701 ya silika wosakanikirana pa 633 nm.
Paralight Optics imapereka mazenera a Brewster amapangidwa kuchokera ku N-BK7 (Giredi A) kapena silika wosakanikirana wa UV, womwe umakhala wopanda laser-induced fluorescence (monga kuyeza pa 193 nm), ndikupangitsa kuti ikhale chisankho choyenera kugwiritsa ntchito kuchokera ku UV kupita kufupi ndi IR. . Chonde onani chithunzi chotsatirachi chikuwonetsa mawonekedwe a S- ndi P-polarization kudzera mu silika wosakanikirana wa UV pa 633 nm pa maumboni anu.
Mawonekedwe:
Zofunika:
N-BK7 kapena UV Fused Silica Substrate
Laser Damage Quantification Test:
Malo Owonongeka Kwambiri (Osatsekedwa)
Mawonekedwe a Optical:
Kutayika kwa Zero kwa P-Polarization, 20% Reflection for S-Polarization
Mapulogalamu:
Zabwino kwa Laser Cavities
Zomwe Zadziwika:
Zojambula za
Window ya Brewster
Chojambula chakumanzere chikuwonetsa kuwala kwa S-polarized ndi kutumiza kwa P-polarized kuwala kudzera pawindo la Brewster. Kuwala kwina kwa S-polarized kudzafalitsidwa kudzera pawindo.

Zithunzi
♦ Chithunzi chakumanja chikuwonetsa kunyezimira kowerengeredwa kwa silika wosakanizidwa wa UV wa kuwala kozungulira pamakona osiyanasiyana a zochitika (Kunyezimira kwa kuwala kwa P-polarized kumapita ku ziro pa ngodya ya Brewster).
♦ Mndandanda wa refraction wa silika wosakanikirana wa UV umasiyana ndi kutalika kwa kutalika komwe kumasonyezedwa mu chithunzi chotsatira chakumanzere (chilolezo chowerengera cha refraction ya UV yosakaniza silica monga ntchito ya kutalika kwa 200 nm mpaka 2.2 μm).
♦ Chithunzi chotsatira chakumanja chamanja chikuwonetsa mtengo wowerengedwa wa θB (angle ya Brewster) ngati ntchito ya kutalika kwa mafunde kuchokera ku 200 nm kupita ku 2.2 μm pamene kuwala kukudutsa kuchokera ku mpweya kupita ku UV silika wosakanikirana.
