Looking into laser light, "safely": real-time visualisation of mode hopping

This poster captures our journey in connecting, adapting and evolving how we teach essential laser characteristics to physics students. By integrating modern spectrometers, we’ve transformed the learning experience, helping students visualise the real-world complexities of laser applications in industry and research. Focusing on the challenging concept of Mode Hopping, this poster dives into our strategies to make this critical aspect more accessible and comprehensible.
