Non-Degenerate Four-Wave Mixing through Rydberg States in a MOT
(2007-07-02)In this work, we use a three-photon near-resonant process in a laser-cooled Rb vapor to achieve phase-matched four-wave mixing using an intermediate Rydberg state. Rydberg atoms in the 36D5/2 state are efficiently produced ... -
Physics Challenges for Spin-Exchange Optical Pumping of He-3
(2009-05-28)Presentation given at the "Physics and Applications of Polarized Noble Gases" workshop at the University of Virginia, May 19, 2009. -
A Portable SERF Magnetometer for Biomagnetic Measurements
(2009-09-10)Recent developments on the UW SERF magnetometer. -
A Portable Ultrasensitive SERF Atomic Magnetometer for Biomagnetic Measurements
(2007-07-02)We present a portable Rb cell atomic magnetometer suited for biomagnetic measurements. Working in the spin-exchange relaxation free regime, we demonstrate an initial white noise floor of 60 fT/sqrt {Hz}. We show an adult ... -

RayTrace
(1998-03-13)This applet traces paraxial light rays through a user-specified system of up to 12 ideal thin lenses and apertures, allowing many simple optical instruments to be modelled. Three examples are given: coupling of light from ... -
Ultrasensitive Atomic Magnetometers
(2009-09-10)We have developed a novel, small-volume portable single-channel atomic biomagnetometer and have used it to detect adult MCG signals. The cryogenic-free magnetometer has sufficiently high sensitivity (20 fT/rt(Hz)) that ...
