The workshop brought together leading international specialists and experts in the field to present the latest findings on a new generation of lasers that are more efficient, safer, and more powerful,<\/strong> aimed <\/strong>at implementation in upcoming extremely large telescope (ELT) projects.<\/p>\n\n\n\n In this context, Ronald Holzl\u00f6hner, Laser Engineer at ESO, explained that the use of artificial stars is crucial for the optimal performance of adaptive optics systems<\/strong>. \u201cYou need an artificial light source in the sky for AO systems to operate successfully. We project a laser along the telescope\u2019s line of sight to create a bright spot that is used as a reference signal to correct atmospheric turbulence,\u201d he noted.<\/p>\n\n\n\n The world\u2019s largest telescopes require increasingly stable, rigid, and high-intensity laser structures<\/strong>. \u201cThe specific challenge is that we need more lasers and higher-power lasers. For this, we distribute several laser projectors around the telescope, and now in the E-ELT we will have six and possibly even eight,\u201d Holzl\u00f6hner added.<\/p>\n\n\n\n The workshop\u2014held for the first time in Latin America\u2014concluded with a technical visit to the AURA facilities, where attendees entered the Gemini South and SOAR telescopes operated by NOIRLab.<\/p>\n\n\n\n Additionally, at the academic event, PhD candidate Vicente Westerhout presented the results of a research project carried out in collaboration with the Australian National University. In his talk Exploring tip-tilt retrieval using an event-based sensor<\/strong><\/em>, he presented advancements in tip-tilt measurement for LGS using low-power, high-speed event-based cameras<\/strong>.<\/p>\n\n\n\n With the goal of expanding the university\u2019s research capabilities, the Vicerrector\u00eda de Investigaci\u00f3n, Creaci\u00f3n e Innovaci\u00f3n PUCV<\/strong> is coordinating the donation process of an astronomical laser from Gemini South<\/a>. This instrument will be installed at the PUCV Space Observatory and will enable students from the School of Electrical Engineering and the Institute of Physics to study adaptive optics at a more advanced level.<\/p>\n\n\n\n Furthermore, Felipe Pedreros, Head of the Laser and Photonics Group at ESO<\/strong>, highlighted the growing contribution of Chilean scientists in this area. \u201cIn the last ten years, there has been remarkable progress in radio astronomy, optical systems, sensing, and adaptive optics. I believe there is a great opportunity for international contribution because there are many highly trained people; we are moving in the right direction,\u201d he emphasized.<\/p>\n\n\n\n![\"\"](\"https:\/\/qommtrue.cl\/optolab\/wp-content\/uploads\/2025\/11\/IMG_5161-1-1024x683.jpg\")
