In our experience, the knowledge of beam shaping techniques, possibilities, and limitations is thus not well disseminated throughout the engineering community. Many of the primary users of beam shaping technology are not necessarily optical experts. A book on beam shaping would thus benefit a wide ...
Modern optical laser techniques based on Spatial Light Modulators (SLM) in holography, display imaging applications get essential benefits from using a laser beam with uniform instead of Gaussian intensity distribution: more predictable and reliable operation, higher efficiency of laser energy usage, more...
Laser Beam Shapin Fred M. Dickey Laser beam shaping, the control of the irradiance and phase profile of the output of a laser, is an enabling technology used in a number of industrial sectors. The author describes the three principal techniques used to accomplish laser beam shaping and the ...
The beam shaping technique mainly uses reflection and refraction techniques to cut and rearrange the slow axis beam to homogenize the beam quality in both axes. There are several beam shaping techniques proposed for the laser diode stacks to improve the symmetry of the beam quality in both axes,...
temporal regimes and microstructural scales. I think beam shaping is really the way to go because it can be applied to print a wide range of metals ubiquitously and be incorporated into commercial printing systems without posing significant integrability challenges as other alternate techniques tend to...
Beam shaping techniques are based on refractive [1], [2], [3], [4], diffractive [5], [6], [7], [8], [9], [10], [11], [12], [13] and even absorptive elements [14]. Usually, beam shaping using a Diffractive Optical Element (DOE) operates on 2-D mode, that is a ...
The study reveals that flexible beam shaping technology surpasses standard AM techniques, albeit with mechanical behavior differing from the original state, requiring further research. Additionally, freeform beam shaping has potential to revolutionize PBF-LB processes, enabling seamless integration with machin...
