... useful microfeatures connected to the burrs. Future work is needed to verify these potential advantages. In LPD, the plasma needed for deburring can also be produced by laser ablation of a sacrifice plate. LPD using a sacrifice plate has been experimentally studied, which can (under the investigated...

... drilling process has been studied, where nanosecond laser ablation is performed under an external magnetic field. The study shows that the magnetic field-assisted laser drilling process produces deeper drilling depth and generates more confined plasma plume and relative less residual, as compared...

...-based model has been applied to study the evolution of plasma produced by high-intensity nanosecond laser ablation in vacuum under external magnetic field. In the early stage (Stage I), the laser-induced plasma generation and its short-term evolution are described through one-dimensional (1D...

...Benxin Wu; Sha Tao; Shuting Lei High-aspect-ratio microholes have many important applications, but their drilling is very challenging. Femtosecond (fs) laser ablation provides a potential solution, but involves many complicated physical processes that have not been well understood, which have...

... hardness. Laser ablation can potentially provide a good solution for silicon carbide micromachining. However, previous studies of silicon carbide ablation by nanosecond laser pulses at infrared wavelengths are very limited on material removal mechanism, and the mechanism has not been well understood...
