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 the first laser and inkjet printers for PCs arrived in the mid-1980s, they could only print in monochrome, and their respective advantages were obvious. Today, the differences between laser and ...

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