Frequency Combs Lasers

Frequency Combs Lasers

Frequency Comb Quantum Cascade Lasers are devices emitting light on a wide spectrum consisting of equidistant peaks in frequency space. The distance between these peaks being fixed, typically given by the pulse repetition rate of a train of ultrashort pulses, they can be used as rulers in the frequency domain for The wide and flat gain spectrum of Broad Gain Lasers make them suitable for operation as Frequency Combs. As the operating range where comb operation can occur is very sensitive to the fine structure of the heterostructure, each QCL-Comb is tested and qualified.
