Simple Scheme For Variable High Power Laser Beam Attenuation, Stephen E. Bialkowski
Simple Scheme For Variable High Power Laser Beam Attenuation, Stephen E. Bialkowski
Stephen E. Bialkowski
A venetian style infrared attenuator placed prior to a pinhole spatial filter results in variable high‐power laser attenuation. This attenuation scheme has a wide dynamic range, results in high‐quality Gaussian beams, does not introduce beam walk‐off error, and is independent of polarization.
