    · With photodiode sensors the bandwidth should be set to “Low” setting; with thermal sensors the acceleration circuit should be shut off. · The detector noise is lowest with Si or InGaAs sensors. © 2017 Thorlabs...

  • Page 11: Power Measurement Of Pulsed Signals

    · The temperature should be stable over the time of the measurement. 4.3 Power Measurement of Pulsed Signals The PM100USB will read the average value of a pulsed signal if the following conditions apply: Thermal Sensor For a thermal sensor, pulse length, repetition rate and peak power are uncritical as long as the peak power is lower than the damage threshold of the sensor.

    The maximum ratings are given in the sensor specifications. The PM100USB can display the actual power or energy density for a known beam dia- meter. For high power or high energy beams a good efficiency can be reached by selecting a sensor with a detector size about 20% - 30% larger than the beam diameter.
