Abstract:
The patent application concerns a laser system for ocean radar applications having a resonant chamber for producing a pair of homogenized, singularly polarized output beams having identical pulse widths and energies. A quarter wave plate is inserted within the optical path of the resonant chamber and rotates the birefringence effects of a laser crystal positioned within the chamber to generate a pair of homogenized, orthogonally polarized beams. A selected one of the orthogonally polarized beams is transmitted through a half wave plate and joins with the remaining beam for passage through a telescope assembly to minimize the cross-sectional area of the beams. A doubler crystal receives the telescoped beams and doubles the frequency thereof to form the pair of homogenized output beams having light energy in the green spectrum.
