TL;DR: In this paper, the optical properties of silicate glasses under high-power, 850-nm femtosecond laser irradiation have been studied and it is believed that these processes result from linear and two-photon absorption of the short-wavelength component of the supercontinuum causing ionization of the glass matrix.

TL;DR: In this article, spherical silicon nanoparticles were prepared by laser ablation of a single crystal Si wafer immersed in 95% ethanol with a pulse duration shorter than the time of electron−phonon relaxation (from 35 to 900 fs).

TL;DR: In this article, the formation of antireflective periodical microrelief on the surface of CVD diamond films was performed by a laser ablation technique by using either a tightly focused beam of a Nd:YAP laser (λ=1078nm) or a projection optical scheme with a KrF excimer laser(λ= 248 nm), and the minimal period of the produced one and two-dimensional surface gratings, consisting of parallel microgrooves or microcraters, was 3 μm.

TL;DR: Ablation tests of AlN, Si3N4, SiC, Al2O3 ceramics, steel and aluminum have been carried out in vacuum, air and argon atmospheres using UV (270 nm), visible (539 nm) and IR (1078 nm) picosecond (100÷150 ps) and nanosecond(6÷9 ns) laser pulses as mentioned in this paper.

TL;DR: In this article, the authors studied the ablative formation of deep channels in steel by femtosecond and picosecond laser pulses and found that a significant screening of the incident energy inside deep channels was found to occur due to the air breakdown at ablated microparticles.
