The PowerPhotonic Variable Beam Shaper is an advanced refractive optical element engineered to transform a single mode Gaussian beam into one of three different output profiles. The output profiles are (i) a Gaussian spot; (ii) a flat top circular spot; (iii) a ring shaped spot. The different output profiles are generated simply and only by varying the input beam diameter. Furthermore, the tuning of the output profile is continuous as the input beam diameter is varied between its minimum and maximum limits.

The Variable Beam Shaper enables users to achieve dynamic beam shaping in their application. This is particularly relevant to industrial laser processes such as laser welding and laser additive manufacturing.

Dynamic beam shaping allows a new level of process enhancements and benefits to be realised. Existing techniques for dynamic beam shaping involve complex and expensive laser systems, or at the very least, complex and expensive laser processing heads.

The Variable Beam Shaper is made from fused silica and inherits the high power handling capabilities (pulsed and CW) of other PowerPhotonic optics.
