Research Areas: Atomic & Molecular Physics, Precision Measurement

Research interests include: laser stabilization and precise scan techniques using interferometry and/or heterodyne techniques; amplitude stabilization near the "photon shot noise" level with classical electro-optical methods; and "squeezed" beams of sub-shot-noise level or of correlated photons produced in nonlinear interactions. Continuous-wave approaches are pursued for application in both gravity-wave antennas and measurement of magnetically induced birefringence of the vacuum. Optical atomic clocks based on a strontium "atomic fountain" will allow the "ultra-resolution" determination of linewidths < 10 Hz. A new modulation detection scheme permits cavity-enhanced nonlinear spectroscopy that provides unprecedented sensitivity (<10-12 absorption) using molecular overtone transitions in the near-visible IR.
