A laser transmitter is provided including a specialized compensator assembly damping mechanism. In accordance with one embodiment of the present invention, a compensator assembly position detector is arranged to detect a position X1 of the compensator assembly with respect to the X-axis, and a position Y1 of the compensator assembly with respect to the Y-axis. The compensator assembly damping mechanism includes an X-axis magnetic damping mechanism, a Y-axis magnetic damping mechanism, and a rotational damping mechanism. The active feedback circuit is arranged to (i) drive the X-axis magnetic damping mechanism so as to increase a damping force generated by the X-axis magnetic damping mechanism as a rate of change of the signal indicative of the position x1 increases, and (ii) drive the Y-axis magnetic damping mechanism so as to increase a damping force generated by the Y-axis magnetic damping mechanism as a rate of change of the signal indicative of the position y1 increases.
