Abstract

Our recent experiment shows that the oppositely directed spontaneous emission from a thin layer of a fluorescence source is highly coherent. It is proposed that a thin layer of gain medium be applied to a ring cavity and be located at the symmetric point from the output coupler so that the spontaneous emission in the laser outputs are correlated and can be removed from a laser beam by destructive interference technique. A theoretical analysis and a physical interpretation for such a spontaneous emission free laser beam are presented. The potential of using the device as an active laser gyro is discussed.
