Noise Measurement——Silicon Photodetector

 
      Noise measurement adopts silicon photodetector to measure the laser beam after attenuation, laser optoelectronic signal shows on oscilloscope via adjust variable attenuator, and noise signal shows by adjust oscilloscope. Laser system output power stability can be judged according to noise signal.
 

Testing Instrument: Silicon Photodetector
