Highly efficient Collimator - Beam Shaper converting Gaussian to Flattop profile for high power TEMoo fiber lasers
With these unique tools the long-standing wish to manipulate the shape of focused beams becomes a reality.
With nearly 100% efficiency the Focal-piShaper produces various profiles:
Flattop
"Inverse Gauss"
"Donut"
"Trident", etc.
Applications:
Microwelding
Drilling
Selective Laser Melting
