To correct for the effects of thermal birefringence in a laser rod (2), the rod is arranged between end mirrors (3) and (4) on a first axis (11), with a quarter wave plate (6) on one side of the rod and a polarising prism (8), on the other side, the polarising prism reflecting light out of the cavity along a second axis (12) to a third mirror (9), and each axis (11), (12) including separate Q switches (7) and (10) arranged to operate in synchronism. <IMAGE> |
