NIST researchers have developed a revolutionary technology for measuring laser power using radiation pressure. The Radiation Pressure Power Meter (RPPM) detects the force light exerts on a highly reflective mirror, allowing precise power measurements even at very high laser powers. This method eliminates the need for large water tanks and enables portable, on-site measurements.
The NIST team is currently developing next-generation instruments like the Beam Box and Smart Mirror to extend radiation pressure measurement capabilities to lower power levels and smaller beam sizes. These technologies will provide more precise measurements for a wide range of laser applications, from medical devices to industrial manufacturing.
The development of radiation pressure-based power measurement techniques is crucial for accurately calibrating lasers across various industries. NIST researchers have made significant contributions to this field through their innovative designs and extensive research, paving the way for more reliable and precise laser power measurements in the future.
