Switchable Fiber Ring Laser Sensor for Air Pressure Based on Mach–Zehnder Interferometer

Applied Sciences, 2023
This work shows a study of pressure gas sensing using an optical fiber interferometer inside a gas cell; here, a thin-core fiber modal interferometer (TCFMI) is fabricated using two distinct types of fiber, a single-mode fiber (SMF model 1060XP) and thin-

Equilibrium energy spread and emittance in a Compton ring: An alternative approach

Physical Review Special Topics. Accelerators and Beams, 2014
In this article the Campbell’s theorem is used to evaluate the equilibrium emittance and energy spread in a Compton ring. This method allows us to have an efficient analytical approach separating the contributions of the Compton cross section from the ...

A generalization of alternative rings [PDF]

Transactions of the American Mathematical Society, 1964
From our earlier remarks it is immediate that these rings are generalizations of alternative rings. In ?2 we show that any ring A satisfying (1), (2), and (3) must be powerassociative and, using this result we obtain an idempotent decomposition for A as A = A1 + A112 + Ao where x E Ai if and only if ex + xe = 2ix for the idempotent e of A.
