Laser Material Processing
TL;DR: In this paper, the effect of reflectivity of the surface, when a pure, monochromatic laser (6) is used, is remedied by the simultaneous application of a relatively shorter wavelength beam (1).

Laser ablation and micromachining with ultrashort laser pulses
X. Liu,D. Du,Gerard Mourou +2 more
TL;DR: In this paper, the mechanisms of ultrashort-pulse laser ablation of materials are discussed, and the differences to that of long laser pulses are emphasized, and some femtosecond laser pulse micromachining results, including comparison with long pulses, are presented.

Laser‐induced breakdown by impact ionization in SiO2 with pulse widths from 7 ns to 150 fs
TL;DR: In this article, the results of laser-induced breakdown experiments in fused silica (SiO2) employing 150 fs −7 ns, 780 nm laser pulses are reported and the avalanche ionization mechanism is found to dominate over the entire pulse width range.

Quintic-phase-limited, spatially uniform expansion and recompression of ultrashort optical pulses.
TL;DR: The system allows one to eliminate spatial inhomogeneities and cubic and quartic phase errors that make existing designs unsuitable for use with pulses much shorter than 100 fs, and is experimentally demonstrate >10,000 times expansion and recompression of ∼25-fs optical pulses.

Multikilohertz Ti:Al 2 O 3 amplifier for high-power femtosecond pulses
TL;DR: This source was used to produce 1 W of femtosecond white light through spectral continuum generation and was amplified at repetition rates of as much as 7.2 kHz in a Ti:Al(2)O(3) regenerative amplifier pumped by a frequency-doubled Q-switched Nd:YLF laser.
