Tobias Donner, Senior Scientist and lecturer in the Quantum Optics Group at the Institute for Quantum Electronics, has received a SERI-financed ERC Consolidator Grant. He plans to use the funding to explore the fundamental principles behind the interaction between quantum many-body systems and light.

Various applications of pulsed laser sources rely on the ability to produce a series of pulse pairs with a stepwise increasing delay between them. Implementing such optical delay scanning with high precision is demanding, in particular for long delays. Addressing this challenge, ETH physicists have developed a versatile ‘dual-comb’ laser that combines a wide scanning range with high power, low noise, stable operation, and ease of use — thereby offering bright prospects for practical uses.
