Flat Top Laser Beam Shaper

Flat top beam shapers used to convert gaussian beams into flat top beams with a uniform intensity distribution are available optimized for laser wavelengths associated with nd yag fiber and co 2 lasers.

Flat top laser beam shaper.

Their optical design makes holography microscopy and system integration suitable especially over great distances. They are also used in very high power laser systems which use chains of optical amplifiers to produce an intense beam. Tophat beams are often used in industry for example for laser drilling of holes in printed circuit boards. A top hat beam shape r also known as flat top beam shaper is the high end option applicable for laser systems that use single mode low m 2 laser beams typically m 2 1 5.

Adloptica works in field of multifocus and laser beam shaping optics finding numerous industrial and scientific applications. This is in contrast to gaussian beams for example where the intensity smoothly decays from its maximum on the beam axis to zero. Flat top laser beam shapers types of analytic top hat beam shapers. Such beam profiles are required for some laser applications.

Conventional diffractive beam shaper requires accurate alignment and beam control. A flat top beam or top hat beam is a light beam often a transformed laser beam having an intensity profile which is flat over most of the covered area. Top hat beam shapers are extensively used in the laser industry mostly in material. Applications of laser beam shapers.

Flat top beam shaper beam shaper is a diffractive optical element that modifies the intensity distribution of the beam. Beam shaping lens is a single optical element for gaussian beam spot profile conversion to top hat beam spot with equal energy distribution within spot size. Edmund optics offers laser beam shaping solutions to collimate laser beams transform beam profiles convert beam shapes and much more. Galilean design thus there are no intermediate focusing of a beam.

Tophat beams are named for their resemblance to the shape of a top hat. Achromatic design provdes this transformation for a certain wavelength range. A flat top laser beam shaper is a diffractive optical element doe that transforms the gaussian beam into a flat top beam with uniform intensity inside a well defined shape with pre designed angular dimensions and a. Almost 100 efficiency spectrum from uv to ir power from mw to kw cw or pulse lasers achromatic design variety of flat top spot sizes low sensitivity to misalignment.

For example a flat top beam shaper creates a far field profile with a uniform intensity in its center. Basic principles of π shaper operation. We offer two types of beam shaping lenses diffractive fbs series lenses which are made of uvfs and refractive gth series lenses which are made of schott glass lf5. Multi year developments are realized in family of pishaper systems 70 models.

Top hat shapers are either refractive or diffractive optics. Tem 00 or multimode with gaussian or similar intensity profile can be applied.
