||Longitudinal Modes in a HeNe Laser
||We have a long-standing experiment to study the atomic physics of a gas laser plasma, using an open-cavity HeNe laser and a grating spectrometer. A similar experiment is done at other institutions. In recent years the experiment has been extended to include an investigation of longitudinal modes using an external confocal Fabry-Perot cavity. Both the experiment and the extensive writing component that accompanies it will be described. Sourcing issues for the HeNe discharge tube will also be discussed.
