Single Mode Laser Beamshapers
Single Mode Laser Beamshapers

Description
PowerPhotonic’s single mode field mappers use a unique freeform direct-write process to fabricate customized single mode beamshaping surfaces in to a fused silica substrate.
These single mode beamshapers are carefully designed to transform a single mode beam into a variety of image shapes at the focus of a lens, providing the highest performance in shape and efficiency without adding additional speckle or diffraction artifacts.
PowerPhotonic’s fabrication technology can generate field mappers to produce a wide selection of shapes and intensity distributions including square, round, annular and more. These field mappers are offered in a 1 optic or 2 optic solution, allowing for optimal tradeoffs between cost and performance.
