Both intensity squeezing and dramatic phase noise reduction have been obtained with a confocal cavity used to feedback the beam from the quantum well diode laser.We have measured an intensity squeezing of 19.3%(37.8% inferred at the laser output) around 35MHz and achieved phase noise reduction of 40—25dB from 9kHz to 100MHz.Quasi-minimum uncertainty state have been demonstrated.
