Factors Affecting the Efficiency of the Micromachining Process
While
most of the unique characteristics associated with micromachining
with ultrafast lasers can be explained by the lack of thermal
diffusion, some important features, notably the extreme high
shot-to-shot repeatability, the ability to create sub-micron
features, and the capability to machine inside transparent
materials, requires a more detailed look at the physics behind
the interaction of light with matter.
How does
light interact with matter? The following links will help
us get a deeper understanding.
