It is sometimes said that science is about truth, while engineering is about compromise. With one laser project in his lab in the University of Colorado's Department of Electrical, Computer and Energy ...

The development of laser frequency combs has revolutionized optical communication, photonic sensing, precision spectroscopy, and astronomical observation. Stable frequency combs could be achieved via ...

Mode-locked lasers are imperative for the generation and application of coherent optical frequency combs. Low noise is necessary for many applications. However, the current super low noise MLLs are ...

New high-performance ultrafast lasers are being made on nanophotonic chips. The new work centers on miniaturizing mode-lock lasers — a unique laser that emits a train of ultrashort, coherent light ...

Nonlinearity-driven NHSE in a topological mode-locked laser. a, Schematic representation of the NH-SSH domain wall implemented in our mode-locked laser’s synthetic lattice. b, Heat map of our ...

Using two mode-locked femtosecond lasers and a single photon counting detector, scientists have recorded broad spectra with close to one hundred thousand colors in almost complete darkness. Our eyes ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...
