Quantitative and Qualitative Study of Gaussian Beam Visualization   Techniques
  We present a comparative overview of existing laser beam profiling methods. We compare the the knife-edge, scanning slit, and pin-hole methods. Data is presented in a comparative fashion. We also elaborate on the use of CCD profiling methods and present appropriate imagery. These methods allow for a quantitative determination of transverse laser beam-profiles using inexpensive and accessible methods. The profiling techniques presented are inexpensive and easily applicable to a variety of experiments.
