The Tunable Continuous Wave Mode Hop Free (CW-MHF) External Cavity Quantum Cascade Laser (ECqcL™) was developed for high-resolution spectroscopy. This high-end system provides “continuous tunability,” also known as Mode Hop Free tuning, over a typical range of 60 cm-1. The combination of a narrow linewidth and excellent wavelength control allows for highly resolved spectral features using broad survey scans. Wavelength modulation over smaller ranges is also a standard feature of the CW-MHF system.
