Currently, laser powers of around 300 to 400 watts are common in many LPBF processes. However, the standard Gaussian laser beam they use has significant disadvantages, says the ILT: the high ...

Due to the coherence between the Gaussian beams and the symmetry of the circular ... substrate by the Singapore Advanced Micro Foundry (AMF) standard 130 nm 8-inch CMOS process.” ...

the focused Gaussian-Bessel beam has its energy spot stretched along the axis of the beam, allowing deeper structures to be defined at one moment. The standard way to convert a Gaussian beam into a ...

EKSMA OPTICS introduces Gauss-to-Top Hat beam shaping lens that redistributes energy of Gaussian beam to a Top Hat beam profile. If a collimated Gaussian beam is used the Top Hat beam shaping lens ...

An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications. Bessel beams look quite ...
