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 ...

Abstract: We have developed an external frequency doubling Nd:YAG laser with high beam quality, side-pumped by a high-temperature semiconductor laser. The beam quality was optimized using an unstable ...

James has been writing about technology for years but has loved it since the early 90s. While his main areas of expertise are maker tools -- 3D printers, vinyl cutters, paper printers, and laser ...
