We demonstrated experimentally the generation of bright amplitude-squeezed light by a continuous-wave quasi-phase-matched degenerate optical parametric deampl ifier based on periodically poled KTiOPO4The threshold of the optic al parame tric oscillator is 35mW. With the pump power of 20mW, the amplitude noise re duction of 223dB is observed directly. It is significant that the amplitude noise reduction of 217dB can be observed only at the pump power of 8mW.
