Prof. Keto's Iodine Stabilized HeNe Laser

This laser was built according to the design of Howard Layer of NIST, described in:

Howard P. Layer, "A Portable Iodine Stabilized Helium-Neon Laser," IEEE Trans. on Inst. and MeasIM-29, pp358-361, 1980.

The assistance of Dr. Layer in constructing this laser is gratefully acknowledged, as is the donation of the 05-LHB-290 plasma tube by Melles Griot.
