This work describes a comparison between nanonewton force references derived from an electrostatic force balance and photon pressure force from calibrated laser optical power in the 1 watt range. The NIST Electrostatic Force Balance (EFB) is used to measure photon pressure force in the 10 nanonewton range from the reflection of a laser from a III-V semiconductor high-reflectivity Distributed Bragg Reflector (DBR) mirror. This work establishes a link between mass, force and laser power within the International System of Units (SI).
