Abstract

A high power laser measuring device based on radiation pressure is built. The mass measurement repeatability and the laser power measurement repeatability were experimentally studied. The experimental results show that the measurement repeatability of the radiation pressure measuring device gradually decreased with the increase of the measured mass and the measured laser power, indicating that the radiation pressure method has more advantages in measuring high power lasers. In the laser power measurement repeatability experiment, the influence of eccentric load and airflow disturbance is avoided, so the laser power measurement repeatability is better than the measurement repeatability calculated according to the equivalent mass.
