WebReflective beam shapers utilizing MPLC are often configured as multi-pass cavities, in which incident laser beams are reflected many times between a reflective phase plate and a mirror to produce the desired output beam profile. These systems benefit from high mode selectivity and low insertion loss. WebBeam Shapers - PowerPhotonic Home 9 Product 9 Beam Shapers Beam Shapers PowerPhotonic designs and manufactures a very wide range of beam shapers. There are a huge range of options, some of which are listed below.
WebIn other words, the field mapping beam shapers πShaper transform the intensity distribution without violating the integrity of the beam and without increasing its divergence. In short, the main features of the refractive field mappers are: - refractive optical systems transforming Gaussian to flat-top (uniform) distribution; WebRefractive beam shapers enjoy widely extended use in many fields and for numerous applications, like the transformation, in laser optics, of Gaussian beams into other shapes more suited to the intended purpose (a top hat, for instance, provides a more homogeneously distributed intensity).
