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: The refractive index of an optical fiber can be locally modified through exposure to femtosecond laser pulses. This feature enables direct inscription of waveguides in the fiber cladding.
