The spectrum of the output from an external-cavity laser containing five discrete diode lasers operating as a coherent ensemble has been shown to correspond to a single mode of the cavity with very narrow linewidth. For cw operation, the linewidth is within the 7.5-MHz measurement resolution. Pulsed outputs from a low-level cw baseline are reported for which the single-mode pulse output is also within the 7.5-MHz measurement resolution. The measured linewidth of the single-mode pulse output with no cw output is 9 MHz.
