Abstract

We describe an oblique incidence optical transmittance difference technique for determining the pointing stability of a laser. In this technique, we follow the angular drift a monochromatic laser beam by measuring the relative changes in transmittance through a parallel fused quartz window for s- and p- polarized components of the beam in response to the drift. This method is shown in the present experiment to have the sensitivity to detect angular changes in the range of 1.7 μradians. To demonstrate the technique we measured the angular drifts of two commercially available lasers.
