Overview of PD300-1W photodiode laser measurement sensor:

The PD300-1W is a photodiode laser measurement sensor measuring to 1W. It has a 10x10mm aperture with swivel mount and a removable filter. Without filter, its spectral range is 350 - 1100nm and its power measuring range is 500pW - 30mW. With filter the spectral range is 430nm - 1100nm and the power range is 200μW - 1W. It has the exclusive Ophir automatic background subtraction feature. The sensor comes with a 1.5 meter cable for connecting to a meter or PC interface.

Problem summary:

Can the PD300 series sensors be used to measure the average power of the pulsed laser？

Generally, yes, but it should be noted that:

The pulse rate should be greater than about 30Hz, otherwise the reading is unstable. At a higher pulse frequency, the sensor will respond as if the beam were CW.

The average power of the pulsed beam may be within the range of the sensor specification, but the energy of the pulse itself is high enough to cause instantaneous saturation of the sensor. It is important to ensure that the pulse energy is also within the sensor specification.

The beam diameter shall not be less than about 1mm.

The average power and power density limits in the specification shall not be exceeded.
