Summary :

Three-wave interactions in a linear, active, and lossless system are investigated. The stability properties of the coupled-waves describing the interaction are discussed at length by taking into consideration possible combinations of parities and directions of group velocities of the component waves. Several schematic dispersion diagrams are presented for the classification of existing instabilities in this system. The power gains of traveling-wave amplification in the three-wave interaction are also analyzed. It is shown that when one passive-wave couples to other two active-waves propagating in the same direction, a power gain considerably larger than that of corresponding two-wave interaction can be obtained.
