Frequency combs have revolutionized time and frequency metrology, making stops along the way to key developments in optical clocks, and, as it turns out, broadband spectroscopy. In a conversation that veers from interferometry to holography, and optoelectronics to solid-state lasing, Nathalie Picque from Max Planck Institute for Quantum Optics shares insights about her latest research. UCLA’s Aydogan Ozcan is back for the second part of a conversation about “Terahertz pulse shaping using diffractive surfaces.”
