Abstract
An absolute instability achieved at a zero-frequency detuning and at an input-signal energy of 10 to the -10th J is described, which has a high weak-signal reflection coefficient of 5 x 10 to the 6th. Absolute instability of the interacting waves is demonstrated both with and without having an external signal applied. The wave detuning can be varied smoothly by means of angular detuning of the oppositely directed pump reference waves, which also permits angular selectivity in the reflection of an external signal.
