In this short post, I shall mostly discuss about using the power meter using a MATLAB class called, “ClassThorlabsPM100D.m” written by Dr. Farfurnik. (It should be available in the shared google drive)
Some primary information about the power-meter:
Type: PM100D
Serial Number: P0045229
Sensor serial number: 240208323
USB Visa address: ‘USB0::0x1313::0x8078::P0045229::0::INSTR’ (I retrieved this address from Keysight Connection Expert Software. When you connect the device via USB, the device is listed in the ‘My Instruments’ tab in the software. The visa address is available there)
Using it from the MATLAB class
pmd = ClassThorlabsPM100D.getInstance() %Creates the object
pmd.connect() %connects the instrument with MATLAB
pmd.SetWavelength(920) % sets the wavelength for the measurement
pmd.GetWavelength() %You can see what wavelength the power meter is currently operating at
pmd.GetPower() % Outputs the power the power meter is currently measuring
