High-powered fiber lasers are making endothermic cutting—using nitrogen, air, and gas mixing—a dominant method, but as Andujo ...

Knowledge of a laser beam's shape and output-power distribution is critical for optimizing laser performance. Neil Savage summarizes the latest beam-profiling products on the market. People using ...

[Jesse]’s modification doesn’t affect the laser beam itself; it is an improvement ... not better. 3D-printed nozzle to promote laminar air flow on the left, stock nozzle on the right.

A powerful laser beam fired from Earth targets a large heat ... As the heated propellant expands, it’s ultimately exhausted out of a nozzle in much the same way as in a traditional rocket.

Near-infrared laser with a wavelength of 1080 nanometres can cause blindness at a power of just five microwatts. The beam intensity that enters these soldiers’ eyes is 200 million times that ...
