Abstract
The interpulse coherence of the pulses within a pulse train from a mode-locked TEA CO2 laser was measured as the path delay of a Michelson interferometer was varied over two wavelengths about a nominal pulse spacing delay of 10.6 ns. An observed visibility of 70 percent was obtained, indicating a linewidth of about 5 MHz for the individual longi-tudinal modes in the gain profile.
