Hi,
I've found this formula on this webite to calculate the power of a laser and was posted by Arayan back in 2011
BP=power/(π(beam diameter-beam divergence*distance)^2)/2
Can anyone please tell me the units?
Power is in watts I assume and divergence in mRad but what about distance and diameter?
Also, is this dependent on the wavelength of the laser?
Thanks
