The Laser Beam: Theoretical Tools
For a ring as a measuring tool, Signal/Noise ratio and line widths are all-important. The signal of the ring as a rotation detector is used, whereas the all-pervasive white, quantum noise is the fundamental noise of the ring. Rings with a low quality factor generate additional low frequency noise. The standard matrix methods for the beam characteristics — curvature and width — are given, as well as the Jones calculus for polarization.

Famous quotes containing the words theoretical and/or tools:
“There are theoretical reformers at all times, and all the world over, living on anticipation.”
—Henry David Thoreau (1817–1862)
“The study of tools as well as of books should have a place in the public schools. Tools, machinery, and the implements of the farm should be made familiar to every boy, and suitable industrial education should be furnished for every girl.”
—Rutherford Birchard Hayes (1822–1893)
