Or worse, you may get a product with unwanted bugs features, like some green lasers that ... a thorough exploration of a wide range of cheap (and not so cheap) lasers in the video below.

As well as being important for basic science, the work could have applications in laser fabrication and imaging. The light-shadow experiment began when physicists led by Raphael Akel Abrahao sent a ...

"This opens up exciting new possibilities for controlling and manipulating light in ways we never thought possible before." The team's experimental setup involved shining a green laser beam through a ...

During our tests, the Huepar proved to be a high-quality laser level, with a bright green beam and a helpful pulse mode. The 360-degree horizontal plane was also nice, particularly when we leveled ...

They shone a green laser beam through the cube while illuminating it perpendicularly with blue light. When the green laser passed through the ruby crystal, it created a region that absorbed more ...
