Quantum Cascade Laser Renaissance
Parametric effects and ultrafast gain dynamics in QCLs lead to single mode instability, multimode
operation and to a new regime, the “harmonic” state, which are opening up new frontiers in frequency combs and RF Photonics

Perfomance Scaling of Ultrafast Lasers via Coherent Combination
Coherent combination of ultrashort laser pulses emitted from spatially-separated amplifiers is a promising power-scaling technique for ultrafast laser systems concerning peak power and average power. In this presentation, the status and prospects of coherently combined fiber-CPA systems will be discussed.
