Lasers around 2 µm drive high-harmonic generation at high photon energies, broadband mid-infrared spectroscopy and efficient THz conversion, and open new routes in silicon processing and polymer welding. Their average powers and pulse energies still lag a decade behind 1 µm technology. We close that gap with holmium- and thulium-based oscillators and amplifiers, which regularly means measuring the properties of the optical materials involved for the first time.
The interactive graph on this webpage provides an overview of published results in the field of ultrashort lasers operating around 2 microns. It visualizes key performance metrics, offering insights into recent advancements. The underlying data is openly available on GitHub, and we encourage the community to contribute by adding new results and keeping the dataset up to date.
