Abstract
We determine the extreme points of the convex set of covariant phase observables. Such extremals describe the best phase parameter measurements of laser light-the best in the sense that they are free from classical randomness due to fluctuations in the measuring procedure. We also characterize extreme fuzzy rotated quadratures.
