Abstract
Electronic laser beam profiling is now a widely accepted method to measure the mode quality and spatial profile of a laser beam. For the most part, profiling has been limited to the unfocused or 'raw' beam, because the energy density or irradiance in the vicinity of focus is high enough to destroy almost any measurement device. Recent developments in measuring technology now enable users to make beam profiling measurements at and near the focus of many lasers. We discuss two new designs and show examples of how they function.
