| Abstract: | An optoelectronic feedback loop intended to suppress intensity noise of a light field is introduced in this paper. A maximum intensity noise reduction of 10 dB is experimentally achieved between frequency of 0?140 kHz on a 1064 nm DPSS continuous wave single-frequency solid-state laser. After optimization and miniaturization, this system is expected to be widely used as a simple ?Noise-Eater?. |
