Abstract

The work addresses the problem of a CO₂ laser dynamics control in the presence of Gaussian white noise in the cavity losses. We improve the delayed continuous feedback method by introducing memory of the previous states. The method proves a powerful one that works for otherwise chaotic dynamics and regular dynamics equally well and it is robust with respect to noise.
