Double-chirped mirrors expand the bandwidth of infrared frequency combs

A novel dispersion-compensation scheme based on double-chirped Bragg mirrors is implemented in a mid-infrared quantum cascade laser. As a result, stable and broadband frequency combs are generated, which are indispensable for high-precision applications in spectroscopy and metrology.
