We investigated the simultaneity of laser longitudinal modes by measuring the optical beats between modes. This simultaneity usually can’t be observed by an optical spectrum analyzer, since a scan time over several tens of seconds is necessary. Through the photomixer, these optical beats are down-converted to the radio frequency region around 1 GHz. For laser chaos, optical beats are more stable than using a conventional continuous wave laser.
