Abstract

The instability and drift in the frequency of an internal mirror He-Ne laser in generally caused by a change in cavity length induced by thermal expansion of the plasma tube. This research developed a simple stabilization technique which is able to stabilize a small He-Ne laser to a fractional frequency stability of 2.3 x 10-11 for a time period between 0.05 and 0.2 seconds. This stability implies that the laser cavity length does not vary more than 0.06 A°. This improved stability will enable more accurate measurements in optical measurements such as spectroscopy, polarimetry and interferometry.
