Abstract :
The excess noise of a CW GaAs diode laser beam has been significantly reduced by optoelectrical feedback of the light noise into the injection current. The feedback signal was centered at a frequency f(30 kHz to 100 kHz) with a bandwidth Δf. The frequency range was limited by the feedback circuit.
