Abstract: An electronic device for generating secure synchronization signals operating with an external clock emitting a first frequency signal is such that for very high resolution synchronization signals, the temporal accuracy of the signals is less than a nanosecond, thereby enabling different elements of a laser pulse chain to be synchronized. The device is provided with securing means having an internal clock emitting an internal clock signal oscillating at a second frequency roughly identical to the first frequency, wherein electronic security management means is arranged so that the internal clock signal replaces the external clock signal and security measures are triggered when the external clock signal is lost, thereby causing the partial or complete stop of the device to be synchronized.
