Traditional methods for accurate measurement of high-power lasers involve total absorption of the laser light [1]. Our method, however, measures photon pressure exerted on a mirror without obstruction of the laser beam. The technique enables in situ

In this article, we document a design process for a feedback controller for a nonlinear electrostatic transducer that exhibits a strong unloaded resonance. This is being used for precision optical power measurement by means of a photon force measurement
