Noise Eater - control electronics for power stabilization of laser beams


Power stabilization of a laser beam using a compact noise eater

The NoiseEater is a compact device for fast stabilization of a laser beam’s intensity, using an electro-optic, acousto-optic, liquid crystal modulator or stepper motor. The NoiseEater takes care of both the processing of a photo-diode input signal and the control of the actuator.

  • Cancellation of intensity noise
  • Controlled laser power setting or switching
  • Fixed or automatic set point adjustment
  • For use with AOM, EOM, LCR or micro stepping motor
