Hi there all,
I am a little confused about polarization. If I have a laser beam incident on a single polariser, if I adjust the angle of the polarizers transmission axis so that it is aligned with the plane of polarization of the incident laser beam does it intensity remain unchanged, or does it lose 50% of its intensity due to Malus's Law?. Also can a polarizer change the polarisation state of the incident beam or will the transmitted beam always be linearly polarised?.
