ABSTRACT:
An improvement for an off-axis, unstable, ring-resonator laser wherein the feedback beam 16 is rotated 90.degree. by a 90.degree. rotator 18 and is then magnified by magnification means 22 so that the dimensions of the rotated, magnified beam 24 will correspond to the dimensions of the gain medium 12 of the laser.
