SAGNAC Spectroscopy.

Abstract

"Sagnac Spectroscopy" is performed by monitoring the change in beat note between counterpropagating beams in a ring laser, while linearly scanning the difference in cavity frequencies for opposite directions. With a sample of Samarium inserted in the laser, resonances associated with the hyperfine splitting are observed, with a resolution better than 10kHz, even though the laser bandwidth exceeds 1THz. The measurements performed leads to a complete determination of the 3x3 density matrix of a lambda or V level system. jg p.1
