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 ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of light and cause tiny distortions in space-time. Albert Einstein predicted ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

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 ...

Scientists have developed an ingenious method to create and control ultra-confined light waves, a significant step towards realizing tiny optical circuits. This method works in two steps, like giving ...

Abstract: As the resolution of laser grating encoders advances from the micrometer to the submicrometer level, subdivision error has become a bottleneck in achieving ...

Abstract: This paper focus on the idea of automatic lightning system and peculiar way of implementation with embedded tool systems. The proposed method is used to measure and control the intensity of ...
