Laser frequency comb

The peculiar physics of quantum cascade lasers has led to the discovery of new frequency comb phenomena beyond traditional ones such as harmonic states, characterized by mode skipping, time-dependent spatial hole burning, turbulent states, recently observed in ring cavities, just to mention a few. These new types of frequency combs open technological and fundamental perspectives, such as laser radio applications and deep connections with passive Kerr microresonators, which are the object of our review.
