1. A laser sensor system comprising:
a high-energy laser (HEL) beam source configured to generate different beams that share a common optical path;
output optics downstream of the HEL beam source along the common optical path; and
a common optical bench arranged along the common optical path downstream of the HEL beam source and upstream of the output optics, the common optical bench configured to receive the different beams and including, in the common optical path downstream of the HEL beam source and upstream of the output optics:
a power filtering device;
at least one collecting optical element optically coupled to and downstream the power filtering device;
a position sensitive detector (PSD) arrangement for measuring angular and positional errors in the different beams, the PSD arrangement being optically coupled to and downstream the at least one collecting optical element; and
at least one compaction optical element optically coupled to the PSD arrangement.
