<p>A polarisation coupled laser having birefringence compensation in which a cavity defused between a pair of total reflectors (4-6) contains a circular laser rod (2), a polariser (1) and pockels cell (5), in which optical rotator means (3-4) (4-9) or (7-8) are formed at one end adjacent the laser rod (2) and include either an optical rotator (3) or a quarter (7) or half (9) wave plate.</p> |
