Flat Top Laser Beam Shaper

Such beam profiles are required for some laser applications.

Flat top laser beam shaper.

Top hat shapers are either refractive or diffractive optics. This is in contrast to gaussian beams for example where the intensity smoothly decays from its maximum on the beam axis to zero. 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. Conventional diffractive beam shaper requires accurate alignment and beam control.

Achromatic design provdes this transformation for a certain wavelength range. Adloptica works in field of multifocus and laser beam shaping optics finding numerous industrial and scientific applications. Applications of laser beam shapers. For example a flat top beam shaper creates a far field profile with a uniform intensity in its center.

Multi year developments are realized in family of pishaper systems 70 models. Basic principles of π shaper operation. Tophat beams are named for their resemblance to the shape of a top hat. 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.

Tophat beams are often used in industry for example for laser drilling of holes in printed circuit boards. Top hat beam shapers are extensively used in the laser industry mostly in material. Flat top laser beam shapers types of analytic top hat beam shapers. π shaper transforms gaussian or similar intensity distribution of source laser beam to a flat top one.

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. Galilean design thus there are no intermediate focusing of a beam. 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. The refractive adloptica πshaper flat top beam shapers create a collimated flat top beam and feature near 100 efficiency with no internal focusing allowing for high power input beams figure 4 and figure 5.

Tl dr q a summary. They are also used in very high power laser systems which use chains of optical amplifiers to produce an intense beam. Edmund optics offers laser beam shaping solutions to collimate laser beams transform beam profiles convert beam shapes and much more. 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.

Tem 00 or multimode with gaussian or similar intensity profile can be applied. Flat top beam shaper beam shaper is a diffractive optical element that modifies the intensity distribution of the beam.
