A method of frequency stabilizing a semiconductor laser. The method includes the steps of detecting a heterodyne beat note by optically mixing a leakage field of an optical resonator (20) and a frequency modulated output of the semiconductor laser (12) and detecting a phase of the heterodyne beat note b y mixing the heterodyne beat note in quadrature with a radio frequency referen ce signal (16). The method further includes the steps of filtering the detected phase of the heterodyne beat note, and modulating the semiconductor laser wi th the scaled detected phase of the heterodyne beat note and the radio frequenc y modulation reference signal.
