Flat wide laser beam lens
WebApr 27, 2024 · This SLAC flat lens has a thickness of 1 µm, a numerical aperture of 0.45, a focal length of 1 mm, a full field of view (FOV) of 32° that enables aberration‐compensated imaging along the focal ... WebThe most simple and direct way to transform a Gaussian beam into a uniform intensity distribution is to pass the beam through an aperture which blocks all but the central, and most uniform portion of the beam (Figure 1). There are two disadvantages to this approach. First, a very large fraction of the laser power is discarded, as much as 75%.

WebNov 1, 2024 · A Flat Top Laser beam is a beam whose intensity profile is uniform inside a certain beam shape, with a sharp drop off at the edges. Unlike the Gaussian beam profile of most laser beams, where the width of the Gaussian spot (above a process threshold) is directly proportional to the energy, a flat Top laser beam profile is characterized by ... Webforms a Gaussian beam of a CO 2 laser to a flattop beam at the focal position. The second element (#2) placed at the focal position collimates the flattop beam by flattening the wavefront (correcting aberrations). Thus, the collimated flat-top beam can propagate a long distance with small intensity variations as shown in Fig. 4.
