Photomechanical laser power measurements with magnetically suspended rotors

Sažetak

Magnetically suspended rotors with virtually no frictional losses could be useful for making high accuracy measurements of laser power. Two different approaches to this problem have been studied. The first involves measurement of the acceleration or deceleration of a spinning rotor due to the application of radiation pressure at its periphery. In the second, either the angle of deflection or the time of swing of a magnetically suspended torsion pendulum is measured as a function of the laser power. Preliminary experimental arrangements for both methods have been devised and are discussed here.
