TL;DR: It is demonstrated that extremely high repetition rates, which make ablation cooling possible, reduce the laser pulse energies needed for ablation and increase the efficiency of the removal process by an order of magnitude over previously used laser parameters.

TL;DR: In this paper, a simple, rapid and inexpensive nanolithography technique is demonstrated that exploits nonlinear feedback mechanisms to tightly regulate the formation of nanostructures induced by femtosecond laser pulses.

TL;DR: In this paper, the authors provide a unified perspective of the unique opportunities created by operating at high repetition rates together with efforts into the development of enabling laser technology, including new results on further scaling up the capabilities of the laser systems.

TL;DR: The data indicate that picosecond-pulsed laser modification can be utilized effectively in low-cost laser surface engineering of medical implants, where different areas on the surface can be made cell-attachment friendly or hostile through the use of different patterns.

TL;DR: In this article, the authors demonstrate burstmode operation of a polarization-maintaining Yb-doped fiber amplifier capable of generating 60μJ pulses within bursts of 11 pulses with extremely uniform energy distribution facilitated by a novel feedback mechanism shaping the seed of the burstmode amplifier.
