We celebrate the International Day of Photonics. Photonics means LEDs, an optical fiber, photovoltaics, lasers. When it comes to lasers. 👩🔬👨🔬 It takes 3 steps (3 laboratories to be precise) to produce device lasers which we are talking about in this movie. Devices (based on lasers), which we fabricate at Infrared Photonics Research Group , find usage in many fields of life: medicine, military, environmental protection, to name a few. 🎬 Watch the following movie to learn more about the process and the amazing field of science that we call photonics!
