Wd. Lee et al., HIGH-RESOLUTION LINE-Q MEASUREMENTS OF VELOCITY-SELECTIVE NONLINEAR FARADAY-ROTATION IN RB VAPOR, Applied physics letters, 63(8), 1993, pp. 1026-1028
Optical feedback from velocity-selective nonlinear Faraday rotation in
alkali metal vapors has been shown to be an effective technique for s
imultaneously stabilizing the frequency and reducing the linewidth of
AlxGa1-xAs/GaAs lasers. The ultimate frequency stability of such a las
er is limited by the quality factor Q=nu0/DELTAnu of this frequency re
ference. In this letter we report the measurement of Q=6X10(6) for opt
ical feedback from velocity-selective nonlinear Faraday rotation in Rb
vapor.
