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].

“…As it is a multi-pulse mechanism of the formation, the speed of the sample surface scanning and pulse repetition rate influence the properties of the resulting TLIPSS. Direct dependency of the orientation on the light polarization demonstrates flexibility of this surface structuring method allowing dynamic change of the TLIPSS direction during the fabrication process by rotating the linear polarization [ 34 ]. Additionally, the period of the structure depends on the irradiation wavelength being somewhat less than

Regulating Morphology and Composition of Laser-Induced Periodic Structures on Titanium Films with Femtosecond Laser Wavelength and Ambient Environment

Recently, highly uniform thermochemical laser-induced periodic surface structures (TLIPSS) have attracted significant research attention due to their practical applicability for upscalable fabrication of periodic surface morphologies important for surface functionalization, diffraction optics, sensors, etc. When processed by femtosecond (fs) laser pulses in oxygen-containing environments, TLIPSS are formed on the material surface as parallel protrusions upon local oxidation in the maxima of the periodic intensity pattern coming from interference of the incident and scattered waves. From an application point of view, it is important to control both the TLIPSS period and nanoscale morphology of the formed protrusions that can be expectedly achieved by scalable shrinkage of the laser-processing wavelength as well as by varying the ambient environment. However, so far, the fabrication of uniform TLIPSS was reported only for near-IR wavelength in air. In this work, TLIPSS formation on the surface of titanium (Ti) films was systematically studied using near-IR (1026 nm), visible (513 nm) and UV (256 nm) wavelengths revealing linear scalability of the protrusion period versus the fs-laser wavelength. By changing the ambient environment from air to vacuum (10−2 atm) and pressurized nitrogen gas (2.5 atm) we demonstrate tunability of the composition and morphology of the Ti TLIPSS protrusions. In particular, Raman spectroscopy revealed formation of TiN together with dominating TiO2 (rutile phase) in the TLIPSS protrusions produced in the nitrogen-rich atmosphere.

“…Such an intensity pattern results in periodic surface structures known as laser-induced periodic surface structures (LIPSSs) [9]. Laser-induced periodic structures have been demonstrated on metals [10][11][12], semiconductors [13], dielectric surfaces [14], and polymers [15] and have been used in various applications [16], including hydrogen sensors [17], plasmonics [18], colorizing metals [19], wettability [20], and tribology [21] applications.…”

Laser Nanostructuring for Diffraction Grating Based Surface Plasmon-Resonance Sensors

The surface plasmon resonance properties of highly regular laser-induced periodic surface structures (HR-LIPSSs) on Si, functionalized with Au nanoparticles (NPs), were investigated. In particular, the spectral dependencies of polarized light reflectance at various angles of incidence were measured and discussed. It is found that the deposition of Au NPs on such periodically textured substrates leads to significant enhancement of the plasmon resonance properties, compared to that measured on planar ones. This effect can be used to improve the efficiency of localized-plasmon-resonance-based sensors.
