Abstract
We have observed the nearly degenerate four-wave mixing (NDFWM) spectrum of Cr : YA103 using a new technique to eliminate the effects of laser jitter. The optical emission resonance at room temperature has a Lorentzian linewidth of 9.8 Hz, in excellent agreement with the measured longitudinal relaxation rate of 9.6 Hz on the 2E - 4A transition of Cr, determined by fluorescence decay.
