Abstract

A new method of stabilizing the output frequency of a He–Ne laser in a longitudinal magnetic field has been developed. With simple modifications to a standard He–Ne laser tube we obtain a frequency stability of <1 MHz (<10⁻⁹) for an averaging time of 1 sec and a long term (5 months) frequency reproducibility of ~±1 MHz.
