This year at the AKL Conference was prominently marked by discussions on Artificial Intelligence (AI). The rapid advancements in AI, significantly propelled by platforms like OpenAI and ChatGPT, have captured the attention of key decision-makers in leading companies such as Trumpf and Coherent. The plenary talk particularly emphasized the potential applications, implications, and the urgent need f...
This post aims to provide comprehensive guidance on cleaning optical elements. While there is a wealth of information available online, particularly on suppliers' websites, I want to consolidate all the knowledge I've acquired over the years working with lasers, fiber optics, and other optical equipment, including some tips and tricks....
Continuing my series of post covering my talk from last Christmas about the use of lasers in space and astronomy. The topic today is adaptative optics. I'll explain the reason why we need it, and how it works in simple terms. Enjoy....
The first image from the James Webb Space Telescope (JWST) was uncover a few days ago [1]. This is truely an incredible image, showing the galactic cluster SMACS 0723, which is slowly becoming the de-facto target for newly deployed space telescopes as it was imaged by Hubble, Planck and Chandra before JWST. This image in particular took the JWST 12.5 hours of exposure to be able to see these objec...
I was at AKL 22 a couple of weeks ago: the international laser technology congress at Aachen, Germany. I was present for the interesting technology conference and the live presentations at Fraunhofer ILT....
I have always been interested with optics and vision. My path led me to a more technological approach of optics, aka photonics, but I still am fascinated by the process of vision. How the image is formed in the eye, how it is interpreted in the brain and so on. This led me to learn a few things that apparently are not so well known about our own eyes. One of these things is the subject of this pos...
Continuing the series on lasers. In the first part, I went fast over plenty of concepts and left others on the side because they were not necessary to get a global understanding of lasers. Here, I want to get a little deeper in some specific concepts. I want to talk more in details about the gain medium of a laser and why population inversion is a vital concept....
So I want to start a series of posts that will focus mostly on lasers, what they are, how they work, what are the most important elements, etc... It can still evolve....
Climate change is a mess. It's hotter in some places, colder in other, and in general, severe weather is intensifying with longer droughts, heavier rainfalls and stronger storms. This problem, caused mostly by our method of generation of energy relying on burning fuel and releasing carbon dioxide in the air has a few solutions, among them: the wind turbine to harvest wind energy and generate clean...

Welcome to my thoughts. I write here about what interests me, my current projects, mostly related to optics, lasers, space, programing and photography. Sometimes other things also. Don't hesitate to contact me!
