ABSTRACT:
An optical parametric amplifier system is used to illuminate an object of interest with a signal beam, and parametrically mix the signal beam from the object with a pump beam to produce a down converted idler beam which maintains an image of the object of interest but which has a frequency which equals the difference between the frequencies of the pump beam and the signal beam. A signal laser is used to illuminate the object of interest, while a pump laser produces the pump beam. A beam combiner mirror produces a combined output by receiving and combining the pump beam and the signal beam. Finally, a nonlinear crystal receives and down converts the combined output of the beam combiner mirror to produce the idler beam by parametrically mixing the signal beam with the pump beam. When a KDP nonlinear crystal is used, the crystal optic axis may be rotated with respect to the direction of propagation of the idler beam to spectally score and amplify the image of the object of interest.
