    Abstract: A pump source configured to generate a pulsed optical beam. The pump source generates a first light beam, a second light beam, and a third light beam, where the first, the second, and the third light beams satisfy a phase relationship. Each of the first, the second, and the third light beams are independently modulated in separate modulation paths and recombined as a pulsed optical beam. A portion of the pulsed optical beam is parametrically amplified within a nonlinear optical medium, where a resulting amplification gain is proportional to a phase difference between the first, second, and third modulated light beams. The power value of the amplified beam is measured as an indication of the phrase difference between the three beams and a corrective phase adjustment based on the error correction signal is applied on any one of the first, second, and third modulation paths to maintain the phase relationship.
