ABSTRACT:
A CPM pulse laser device is provided which has a means for emitting pulses in two separate directions. A return system is provided for returning one of the pulses to the laser resonator in such a manner that the returned pulse is superposed on the other pulse which was propagated in the other direction. The return system preferably includes a total reflecting mirror or a nonlinear crystal. The position of the total reflecting mirror or nonlinear crystal is precisely adjusted to create the superposition.
