The emission properties of an Amplitude Modulated diffraction limited external cavity multi-stripe high power laser diode are here reported. When resolving the resulting electric phase in the far field, a stabilization of a factor of 10 is obtained compared to the free running laser diode. Such a device is of interest for free space optical communication and range-finding. An original method based on white-light interferometry is also reported for measuring the reflection coefficient of the anti-reflection coated facet of the laser diode.
