PRIME stands for Psuedo Random Intensity Mapping Element. It uses a unique free-form direct-write process to fabricate a highly non-uniform surface in fused silica. PRIME beamshapers are designed to transmit a well-defined and controlled divergence angle with potential transmission efficiencies of 99%. The target applications for this technology are high-power materials processing, such as welding, brazing, cladding, and metal polishing, and pump beam homogenization. The system allows for a dramatic increase in beam uniformity, high power handling, high laser damage threshold, and no focal plane shift, among many other benefits.
