Measuring Laser Power Below the Noise Floor with a Lock-In Amplifier

Measuring optical signals in the femtowatt (10-15) to nanowatt (10-9) range can be very challenging. Signal levels this low are lost in typical detector noise levels and swamped by background light. The noise floor for photodiode detectors operated with a small bandwidth (~10 Hz) is on the order of 1 picowatt (10-12). Further narrowing of the bandwidth by filtering or averaging will only provide a small additional reduction in the noise level.

High Power Industrial Laser Measurement: Overcoming Obstacles with the Helios Sensor

Measuring high power laser beams in a production environment comes along with several hurdles.  Here are some of the common issues that need to be addressed:

  • Water cooling
  • How to minimize laser down-time
  • How to keep the sensor clean
  • What kind of industrial communication interfaces to use

Keep Cool: Avoiding Sensor Drift

In theory, there is no difference between theory and practice.

In practice, there usually is.

When a laser power sensor is rated for up to some maximum average power, that means 2 things:
