quantum cascade laser

Quantum Cascade Lasers (QCL) are designed for the MIR spectral range from 4µm to 12µm. QCLs enable access to wavelengths which are important for molecule spectroscopy.

Wavelength Section Types:
Quantum Cascade Lasers are available as longitudinally single-mode as well as longitudinally multi-mode devices:
  • Fabry Perot Quantum Cascade Lasers (FP QCLs) operate longitudinally multi-mode and offer high output power.
  • Distributed Feedback Quantum Cascade Lasers (DFB QCLs) operate longitudinally single-mode with slightly reduced output power in comparison to the FP models.
Types of QCL

Pulsed Quantum Cascade Lasers, which will be operated in a short pulse mode with a typical pulse duration of 150ns.
​
CW Quantum Cascade Lasers, which will be operated in a continuous emission mode.
