| description | A method and apparatus for providing coincident orthogonally-polarized laser beams having twice the frequency of a fundamental frequency emitted by a laser source is disclosed. A second harmonic generator within a laser resonator cavity causes frequency-doubled laser beams to travel in opposite directions along an axis thereon. One of the beams undergoes a polarization change of substantially 90 DEG and is returned for travel along the laser axis in the same direction as a second frequency-doubled beam which has not undergone a polarization change. The orthogonally-polarized beams are then emitted through an output mirror designed for transmitting beams of twice the frequency of the fundamental beam. |
