Abstract
Embodiments of the present invention include a backscatter reductant anamorphic beam sampler. The beam sampler can be implemented to measure a power of a reference beam generated by an electromagnetic radiation source in proportion to a power of a working beam. The beam sampler can provide astigmatic correction to a divergence of the working beam along one axis orthogonal to a direction of propagation. The beam sampler can further be implemented to prevent backscatter reentrant radiation from impinging upon a photodetector of the beam sampler resulting in a reduction of error and instability in an assay of the working beam.
