Advances in Ultrafast Laser Microprocessing
2003
NIHON GAZO GAKKAISHI (Journal of the Imaging Society of Japan)
We review recent advances in ultrafast laser technology as applied to the fi eld of ultra-fi ne materials processing. Ultrafast lasers are a class of lasers that produce pulse widths of from picoseconds to femtoseconds. The most important characteristics of ultrafast laser-matter interaction include precise ablation threshold and absence of heat diff usion into the material during laser irradiation, both of which are due to the short temporal duration of the laser pulse. As the laser pulse
