Abstract
A simple CO2 laser can be caused to exhibit a specific sequence of five rotational lines or "colors" with cavity length tuning. The sequence, useful in multicolor interferometric distance measurement, is predicted to appear only near certain discrete laser cavity lengths. Three different length breadboard lasers are described in which a desired sequence is found.Keywords
