I-Brewster Windows ngaphandle kokulahlekelwa kwe-Reflection ye-P-Polarization
Amafasitela e-Brewster ngokuvamile asetshenziswa njengama-polarizers ngaphakathi kwemigodi ye-laser. Uma ibekwe ku-engeli ye-Brewster (55° 32′ ku-633 nm), ingxenye yokukhanya e-P-polarized izodlula efasiteleni ngaphandle kokulahlekelwa, kuyilapho ingxenye yengxenye ye-S-polarized izoboniswa efasiteleni le-Brewster. Uma isetshenziswa endaweni ye-laser, iwindi le-Brewster lisebenza njenge-polarizer.
I-angle kaBrewster inikezwa ngu
i-tan (θB) = nt/ni
θBi-engeli kaBrewster
niinkomba yokuphindwa kabusha kwendlela yesigameko, engu-1.0003 yomoya
ntinkomba yokuphindaphinda kwe-transmitting medium, engu-1.45701 ye-silica ehlanganisiwe ku-633 nm.
I-Paralight Optics inikeza amafasitela e-Brewster enziwe asuka ku-N-BK7 (iBanga A) noma i-silica ehlanganisiwe ye-UV, engabonisi nhlobo i-laser-induced fluorescence (njengoba ilinganiswa ngo-193 nm), okwenza kube ukukhetha okuhle kwezicelo ezisuka ku-UV ukuya ku-IR eseduze. . Sicela ubone Igrafu elandelayo ebonisa ukubukeka kwakho kokubili i-S- ne-P-polarization ngesilica ehlanganisiwe ye-UV engu-633 nm ukuze uthole izithenjwa zakho.
Izici:
Okubalulekile:
I-N-BK7 noma i-UV Fused Silica Substrate
Ukuhlolwa Kokulinganisa Kokulimala Kwe-Laser:
I-High Damage Threshold (Ayigcotshiwe)
Ukusebenza kwe-Optical:
Ukulahlekelwa kwe-Zero Reflection kwe-P-Polarization, i-20% Reflection ye-S-Polarization
Izicelo:
Ilungele i-Laser Cavities
Imininingwane Ejwayelekile:
Umdwebo Wezithenjwa we
Iwindi leBrewster
Umdwebo oyisithenjwa ongakwesokunxele ubonisa ukukhanya kwe-S-polarized kanye nokudluliselwa kokukhanya kwe-P-polarized ngewindi le-Brewster. Okunye ukukhanya kwe-S-polarized kuzodluliswa ngefasitela.

Amagrafu
♦ Igrafu engakwesokudla ibonisa ukubaleka okubaliwe kwe-silica ehlanganisiwe ye-UV yokukhanya kwe-polarized kuma-engeli ahlukahlukene wesigameko (Ukubonisa ukukhanya kwe-P-polarized kuya kuziro ku-engeli ye-Brewster).
♦ Inkomba ye-refraction ye-silica ehlanganisiwe ye-UV iyahlukahluka ngobude begagasi obuboniswe kugrafu elandelayo engakwesobunxele (inkomba ebaliwe yokuphindwa kwe-silica ehlanganisiwe ye-UV njengomsebenzi wobude beza kusuka ku-200 nm ukuya ku-2.2 μm).
♦ Igrafu elandelayo yesandla sokudla ibonisa inani elibaliwe lika-θB (i-engeli ye-Brewster) njengomsebenzi we-wavelength ukusuka ku-200 nm ukuya ku-2.2 μm lapho ukukhanya kudlula emoyeni kuya kusilica ehlanganisiwe ye-UV.
Inkomba ye-refraction incike ku-Wavelength
