By: O. J. Allegre, W. Perrie, K. Bauchert, G. Dearden, K. G. Watkins Laser Group, School of Engineering, University of Liverpool, UK Boulder Nonlinear Systems, Inc., Colorado The past decade has seen the development of ultra-short pulse lasers, with processes based on femtosecond and picosecond pulse durations becoming increasingly widespread. Thanks to the ultra-short timescale on […]

Texturing structures of Ti films by multiple femtosecond laser pulses
By: Yongguang Huang Femtosecond laser texturing has proved to be a particularly powerful method for creating a wide variety of surface structures on the metal films, such as a hollow microbump-nanojet sturcture and disk-column-nanodroplet structure on the gold films. The process of femtosecond laser texturing does not rely on material removal, but on hydrodynamic flow […]
