Newport (Irvine, CA) has introduced a new refractive beam shaper that converts Gaussian laser beam input to produce a collimated, flat-top beam that can propagate without change in power and intensity ...

Laser beam interactions with plasma are at the forefront of contemporary high-energy density physics, offering transformative potential in areas ranging from inertial confinement fusion to advanced ...

Laser powder bed fusion (LBPF), a 3D printing technique commonly used to make metal parts, creates large thermal gradients between areas hit by the laser and areas not being struck. This creates pools ...

Fraunhofer ILT says custom beam profiles improve component quality, cut material losses. LCoS-SLMs can be used to generate almost any beam profile in the LPBF process. Click for info. A new approach ...

Engineers have succeeded in fabricating a nickel single crystal with only a very few crystalline defects by irradiating nickel powder with a large-radius, flat-top laser beam (i.e., a laser beam whose ...

A beam profiler is an essential tool for any laser user. Carlos Roundy describes the options available and how to pick the right profiler for your application. Every laser user knows that they need a ...

Schematic diagram of the beam homogenization method based on polarization-encoded metasurface. QWP quarter-wave plate, PD photoelectric detection. The inset in the upper right corner illustrates the ...

NIMS and Osaka University Graduate School of Engineering have succeeded in fabricating a nickel single crystal with only a very few crystalline defects by irradiating nickel powder with a large-radius ...
