I-Brewster Windows ngaphandle kokulahlekelwa kwe-Reflection ye-P-Polarization

Ama-Brewster Windows ama-substrates angamboziwe angasetshenziswa ochungechungeni njengama-polarizer, noma ukuhlanza i-polarized beam.Uma ibekwe ku-Engeli ka-Brewster, ingxenye yokukhanya e-P-polarized ingena futhi iphume ewindini ngaphandle kokulahlekelwa kokubonisa, kuyilapho ingxenye ye-S-polarized ibonakala kancane.Ikhwalithi yendawo engu-20-10 ye-scratch-dig kanye nephutha elingu-λ/10 elidluliselwe ngaphambili kwegagasi lamafasitela e-Brewster abenza kube ukukhetha okuhle kwemigodi ye-laser.

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 (θ_B) = n_t/n_i
θ_Bi-engeli kaBrewster
n_iiyinkomba yokuphindaphinda kwendlela yesigameko, engu-1.0003 yomoya
n_tinkomba 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:

pro-ehlobene-ico — 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.
