Abstract
The heterodyne detection efficiency of coherent laser radars is maximized coaxially aligning the local oscillator (LO) beam and the received laser beam when combined at the detector by preventing interference between the counterpropagating waves in the lasing rod within the lasing cavity by using optic polarization, magneto-optic polarization, and cavity end partial reflectors.
