You can hear sound, of course, but what if you could see it with a laser? That’s what [Goosetopherson] thought about, and thus a new project that you can see in the video below was born. The ...

During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...

Now researchers in Japan have reported the world’s first continuous-wave UV-B semiconductor laser diode operating at room temperature on a low-cost sapphire substrate. This breakthrough by researchers ...

Use code FORBESVETTED50 to take an extra $50 off the Omnilux Contour Face, our pick for the best silicone mask. Red light therapy has long been used to reduce inflammation and improve skin texture, ...

Considering a laser hair removal service? I get it, and I've actually tried them. My review? They're painful, expensive, and take a lot of sessions to see results. Soon, I'm running right back to ...
