A brief introduction into Raman spectroscopy and related applications. An overview over the physics, the requirements on the laser source and the detector properties necessary to detect a proper spectrum. ...
Lasers are the ultimate surgery tool in ophthalmology and retinal laser photocoagulation is the gold standard for the treatment of common eye deseases such as age-related macular degeneration (AMD) and diabetic retinopathy. ...
Packaging diode laser arrays. Why and how? Edge-emitting semiconductor laser arrays (or laser bars) are surely the best-known and still the most widespread architecture of high power diode lasers (HPDLs). Under an electron-pumping scheme, these structures are nowadays capable of generating up to 500 W of...
Abstract This article proposes a modelling method of laser diodes optical output power, especially for mid-high power diodes working in continuous wave (CW) or quasi continuous wave (QCW) modes, and focusing in the optical output power dependency on temperature and its model implementation in Pspice, targeting...
The CaliBend research and development project aims at strengthening the future and innovative capacity of small and medium-sized enterprises (SME) in the area of sheet metal processing. These are confronted with new technological customer requirements, e.g. use of high-strength steels and small bending radii. In...
Overview Unwanted body hair removal is a very common and widespread practice around the globe, rapidly growing in the last few years, addressing both men and women. Since the late 90’s, light-assisted hair removal (LHR) techniques have shown unsurpassed effectiveness compared to traditional methods, allowing an almost...
The ExoMars program has been established by the European Space Agency (ESA) to investigate Martian environment and to demonstrate new technologies that will be necessary in future missions. To meet the programme objectives, ExoMars has foreseen two space missions. First mission, already launched on 14...
The main goal of this little blog post is to give your mind and curiosity a vivid view on how laser wavelengths are getting absorbed by different colors. Once you know the answer to this question, you can apply it to different scenarios that you...
