Abstract
  • Intensity beam profiles of a 633 nm laser off a super-polished glass surface were captured using surface polarization reflection. Profile capture can be difficult due to the relative intensities of molecular reflection versus macro reflection. Surface polarization reflection uses parallel polarized light incident at Brewster’s angle to extinguish macro reflection. A jet of weakly interacting gas is focused on the super-polished glass, the profile is captured, and the control intensity profile is subtracted to deduce the effects of Van der Waals interactions on surface polarization reflection. The optical arrangement uses a 25 micron spatial filter, a crystal polarizer, and a 375 x 242 pixel SBIG CCD camera. Thermal stabilization of the laser diode as well as data acquisition and processing will be discussed.
