Abstract
We report a new mechanism for the secondary instabilities of traveling wave patterns in dissipative systems. In close analogy to nonlinear optics and plasma physics, it is a process of three-wave interaction that leads to sum-frequency generation. The primary traveling wave gives rise to two additional wave components, an upper and a lower frequency. We outline the mechanism and we show that this process does occur for wave patterns obtained in an optical experiment.
