Quantum Cascade Lasers

Frequency Comb 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 Frequency Comb Spectroscopy.

In the mid-infrared range, Quantum Cascade Lasers with specifically engineered optical dispersion have been shown to emit broad and powerful optical frequency combs. As for ultrashort-pulse lasers, the mode spacing of QCL combs is given by cavity length. However, in the case of QCLs, the periodic modulation in the time-domain is of the FM, not AM, type and the output power is constant.

S-3 Pulser

The new S-3 High Power Pulse Generator is designed to drive devices requiring short or long pulses of high current with a non-linear response, including optical devices such as high power quantum cascade lasers, infrared laser diodes, LEDs or electronic devices such as Gunn diodes or high speeds transistors and rectifiers.

The S-3 is a good replacement for the obsolete Keysight/Agilent 8114A or the AV-107 from Avtech and provides additional features.
