TKSA laser shaft-alignment tools are for aligning the shafts of rotating machinery. They use a Class 2, 670 to 675-nm diode laser to measure shaft alignments between brackets 2.7 in. to 3.3 ft apart.

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 ...
