Abstract:
We report on a new laser feedback mechanism that uses speckle-pattern phenomena to create highly dispersive feedback. This speckle mirror is capable of creating laser emission as narrow as that from laser cavities using a number of dispersive elements such as gratings and prisms. Contributions from the peaks of intensity of the speckle patterns and a limited pumping-beam diameter are the basic conditions for the observation of this effect.
