The fabrication of specific surface features requires an adequate level of repeatability to be applied in industrial production environments. Although reference is frequently made to repeatability as a strength of many micro-machining techniques, few works in the literature have been dedicated to systematic and quantitative study of this parameter. The purpose of this work was therefore to quantitatively analyze the repeatability of textured surfaces with an original approach. Aluminum alloy substrates were textured with nanosecond laser pulses to produce micro-dimple arrays. Such features are widely employed to enhance wettability and tribological behavior, for which analysis was performed in terms of interfacial area and void volume. To give the work a more general character, two other parameters based on the definition of the Pearson's Correlation Coefficient were also tested and compared to find the most suitable parameter for assessing repeatability for a given application. Finally, a study of the point-to-point repeatability of single surface features was conducted to detect variations in process repeatability in different portions of the same processed area. For the specific laser texturing process considered, it was found that an increase in total energy dose led to improved process repeatability.

“…Laser induced breakdown spectroscopy measurements were performed with custom-made setup [20,21] based on a pulsed solid state Nd:YAG laser (1064 nm, 10 ns, 10 mJ/pulse, 5 Hz, M 2 =5) and the spectrometer equipped with gated detector. Laser plasma was generated in air by focusing laser beam normally at the sample surface with microscope objective (4x, focal length 15 mm).…”

The International Year of Light 2015 was a landmark for the laser and optics community pointing the way to a bright future for humanity and the environment. It is with great satisfaction that Laser Physics and Laser Physics Letters have published many notable articles that have contributed to the development of light-based technologies and breakthroughs in photonics. In recognition of their high quality, we present a selection of some of the most popular articles published by Laser Physics and Laser Physics Letters throughout 2015, all of which are believed to have the potential to make a high impact on future research directions. Those chosen are recognised for their high-interest with readers and importance in the field, providing a snapshot of the broad subject coverage and international make-up of both journals.Starting this year, we will be recognising and announcing annual highlights of a previous year for both journals. We hope that you find these highlights useful and look forward to publishing more cutting-edge work in the year ahead.Summary of the highlights articles: Physics of lasers• • Experimental investigation of the light shift effect in an optical-magnetic double resonance system-an experimental scheme for studying the light shift effect in an optical magnetic double resonance system by using 4 He atoms is demonstrated [3]. • Enhanced random lasing from a colloidal CdSe quantum dot-Rh6G system-randomlaser action in a system where optical amplification is provided by colloidal CdSe quantum dots triggered by the emission from Rhodamine 6 G is reported [4].• Ultra-short pulse generation in the hybridly mode-locked erbium-doped all-fiber ring laser with a distributed polarizer-ultra-short pulse generation in a dispersion-managed erbium-doped all-fiber ring laser hybridly mode-locked with boron nitride-doped singlewalled carbon nanotubes, in co-action with a nonlinear polarization evolution in the ring cavity with a distributed polarizer, is reported for the first time [5].• Analysis of pump excited state absorption and its impact on laser efficiency-a model to quantify the effect of excited state absorption at the pump wavelength on laser efficiency, threshold and heating is developed [6]. Fibre optics and fibre lasers• 80 fs passively mode-locked Er-doped fiber laser-an Er-doped laser that has an all-fiber design, including the dispersion compensation and external compression stages, forming a robust and compact device, is reported [7].• Bound-state fiber laser mode-locked by a graphene-nanotube saturable absorbermultiple bound states in a linear-cavity fiber laser mode-locked by a mixture of graphene and single-walled carbon nanotubes is experimentally observed [8].
