Abstract

Using reflection, radiation pressure (RP) sensors provide a means for in-situ power measurement simply and accurately. The first realization of multi-kW RP power meters (RPPM) established a new paradigm of optical power measurement technology [1]. Our objective is to advance this technology and bring about smaller, faster, and more sensitive devices. Earliest testing of a miniature prototype silicon spring integrated with a capacitive bridge displacement sensor that promises to improve measurement sensitivity and speed is presented. We show a reduction in thermal strain of the device by adding a strain balancing metal coating and demonstrate the open loop response of the detector to laser pulses from 100 ms to 2 s duration.
