A wavefront folding Mach-Zehnder interferometer together with a fast gated diode array detector has been used to measure the temporal evolution of transverse coherence during the pulse from a copper vapour laser. The transverse coherence has been found to increase stepwise from a low initial value up to complete transverse coherence at the end of the pulse. The results are found to be in excellent agreement with theoretical predictions.
