Abstract
Recent theoretical attention has been given to the production of squeezed photon states[1] and a decrease in noise level below the quantum limit has been reported.[2] We consider here a new method which should not only provide a substantial reduction in common sources of amplitude noise, but also may reduce shot noise below the level expected from the quantum effect. This type of device, which we will refer to as a Laser Stabilitron, involves a three mirror system in which two coupled cavities are produced. One cavity contains an amplifier, and the other contains a saturable absorber. Due to nonlinear effects, there are two regions of operation in the system: One of these is characterized by hysteresis and instability. The other is stable and should permit strong suppression of fluctuations in the laser intensity.
