Fabry-Pérot etalon walk-off loss in ring cavities — •Ulrich Eismann — Université Pierre et Marie Curie - Paris VI, 4 place Jussieu, 75252 Paris, France — Present address: LNE-SYRTE - Observatoire de Paris, CNRS, UPMC, 61 Avenue de l’Observatoire, 75014 Paris, France.

Single-frequency lasers have found widespread applications in science and technology. Many current designs require intracavity Fabry-Pérot etalons as frequency-selective elements.

I present both analytic and numeric calculations of the walk-off loss, inevitable when installing an etalon in a laser cavity. I treat the case of a single pass of a gaussian beam through the etalon, which corresponds to the practically important situation of a ring laser operating on its fundamental mode. I furthermore compare to former results obtained for a linear resonator geometry, and draw important conclusions considering single-frequency laser designs.
