Stabilization of terahertz wave generation by using chaotic oscillation in a laser

Stabilization of a THz Wave using a chaotic oscillation in a multimode semiconductor laser with an optical delayed feedback by the external mirror is investigated. In this paper, the spectrum of laser chaos is compared with that of the CW steady state oscillation, and the broad spectrum is confirmed in the case of chaotic oscillation. Stabilization and the wide spectrum of THz waves are also obtained in the case of using a chaotic laser compared with that of using a CW steady state laser.
