How to determine the Intensity or power of laser beam knowing only the beam divergence and beam diameter?
I have a 200mW laser pointer since it's China made I have to recalculate. The I have a beam divergence equation =2arctan(d'-d/2L) and beam diameter experimentally (measured manually) So from there how do I calculate for intensity or even the power of the laser? many thanks
