Article Abstract
This paper presents an extensive analysis of the operating principles, theoretical background, advantages and limitations of laser-based lighting systems. In the first part of the paper we discuss the main advantages and issues of laser-based lighting, and present a comparison with conventional LED-lighting technology. In the second part of the paper, we present original experimental data on the stability and reliability of phosphor layers for laser lighting, based on high light-intensity and high-temperature degradation tests. In the third part of the paper (for the first time) we present a detailed comparison between three different solutions for laser lighting, based on (i) transmissive phosphor layers; (ii) a reflective/angled phosphor layer; and (iii) a parabolic reflector, by discussing the advantages and drawbacks of each approach. The results presented within this paper can be used as a guideline for the development of advanced lighting systems based on laser diodes.

Untethered microrobots hold significant promise in fields such as bionics, biomedicine, and micromechanics. However, replicating the diverse movements of natural microorganisms in artificial microrobots presents a considerable challenge. This paper introduces a laser-based approach that utilizes lattice metamaterials to enhance the deformability of hydrogel-based microrobots, resulting in untethered light-driven lattice soft microrobots (LSMR).

Hierarchical surface structuring is a critical aspect of advanced materials design, impacting fields ranging from optics to biomimetics. Among several laser-based methods for complex structuring of photo-responsive surfaces, the broadband vectorial interferometry proposed here offers unique performances. Such a method leverages a polychromatic laser source, an unconventional choice for holographic encoding, to achieve deterministic multiscale surface structuring through interference light patterning.

Introduction: Post-inflammatory hyperpigmentation is a common dermatologic complaint that affects different parts of the body. Axillary hyperpigmentation (AH) is a common dermatologic complaint, with no standard treatment. We aim to address the efficacy and safety of the studied treatment modalities for AH.

Water droplets, acting as natural bioreactors and optical whispering-gallery-mode (WGM) resonators, hold the potential for laser-assisted analysis. However, water/aqueous droplet lasers can only survive in air with a limited lifespan (<100 s) due to rapid evaporation, restricting their applications in bioreactions. To address this challenge, we introduce laser-emitting aqueous bioreactors (LEABs) in fluorocarbon oils.

We established a theoretical model that revealed the oscillation mechanism of the dual-wavelength SLM Q-switched laser operation. Fabry-Perot (F-P) etalons were used as auxiliary mode-selection elements, which not only enabled gain control for the two wavelengths, but also enhanced the side-mode suppression capability of the pre-laser Q-switching process.
