A pulsed laser beam aiming apparatus is configurated such that substantially 100 of the energy from a pulsed laser beam from a Q-switched pulsed laser device ic accurately aimed at a distant targetobstacle in space. The pulsed laser beam is reflected off of a multifacet polygonal mirror spinning about its axis and perpendicularly affixed to a rotatable azimuthal table wherein the spinning mirror provides elevational orientation, and, in conjunction with the rotatable azimuthal table, azimuthal orientation. Control circuit and associated equipment cause the Q-switched pulsed laser device to be triggered on when a facet of the mirror is in the proper elevational and azimuthal orientation for the pulsed laser beam to hit the targetobstacle. correct aiming of the pulsed laser beam at the targetobstacle is accomplished when the coordinates thereof are specific only as an elevational angle 5 above andor below the horizon and an azimuthal angle between 0 and 360 degrees.
