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
The NoiseEater contains the following components:
- Photo diode amplifier (PDA)
- Regulator section with PI-regulator
- Optional: VCO (voltage controlled oscillator) and modulator as well as RF-amplifier to control an AOM
- Optional: drivers for HV or RF, resp
