Ultrafast lasers are ideal tools to process transparent materials because they spatially confine the deposition of laser energy within the material’s bulk via nonlinear photoionization processes. Nonlinear propagation and filamentation were initially regarded as deleterious effects. But in the last decade, they turned out to be benefits to control energy deposition over long distances. These effects create very high aspect ratio structures which have found a number of important applications…
