Picture Title: Production of a Quartz Octagonal Optical Cell with AR Coated Windows by Ronald A. Bihler*

Poster presented at the 52^nd ASGS Symposium, Portsmouth, VA, June 21-23, 2008.

Abstract: Experimentation in Bose-Einstein Condensation is a constantly evolving field with more demanding requirements for a higher quality optical cell. The following illustrations describe the assembly stages for manufacturing an octagonal optical cell with AR coated windows, utilizing a precision-machined quartz frame.

Abstract: Spin exchange Relaxation Free (SERF) Magnetometers require cells that contain potassium vapor and buffer gas. The unpaired electrons on the potassium atoms are spin-polarized by a pump laser. A perpendicular probe laser detects the precession of the electron spin in the presence of a magnetic field. Because of the use of the lasers (the restrictions of metals and the optical detector (required to measure the atomic response to fields)), glass materials are required. More specifically, glass cells of various geometries and optical specifications have to be constructed according to a particular field or specimen. In this case, we will describe the construction of large rectangular optical cells used in biomagnetic imaging.
