O fa'amalama Brewster e masani ona fa'aaogaina e fai ma polarizer i totonu o le laser cavities. Pe a faʻatulagaina i le pito o Brewster (55 ° 32 'i le 633 nm), o le P-polarized vaega o le malamalama o le a pasi atu i le faamalama e aunoa ma se gau, ae o se vaega o le S-polarized vaega o le a atagia mai le faamalama Brewster. Pe a faʻaaogaina i totonu o le laser cavity, o le faʻamalama Brewster e matua galue o se polarizer.
O le tulimanu a Brewster e tuuina mai e
tan(θB) = nt/ni

nio le fa'ailoga o le fa'afoliga o le mea na tupu, o le 1.0003 mo le ea
nto le fa'ailoga o le fa'aliliuina o le ala fa'asalalau, o le 1.45701 mo le silica fused i le 633 nm.
Paralight Optics ofo atu Brewster faamalama e fau mai le N-BK7 (Vaega A) poʻo le UV fused silica, lea e faʻaalia toetoe lava leai se laser-induced fluorescence (e pei ona fuaina i le 193 nm), ma avea o se filifiliga lelei mo talosaga mai le UV i le latalata IR. . Fa'amolemole va'ai le Kalafi o lo'o fa'aalia ai le fa'ata'ita'iga mo le S- ma le P-polarization e ala i le UV fused silica i le 633 nm mo au fa'amatalaga.
