External-Cavity Widely Tunable Quantum Cascade Lasers BG-10-12
External-cavity quantum cascade lasers both narrow the laser linewidth and extend the wavelength tuning range, making them well suited to high-resolution gas-molecule spectroscopy. Spectra-line supplies external-cavity quantum cascade lasers manufactured by ALPES. External-cavity assemblies allow flexible replacement of FP and broadband gain chips for highly flexible configurations, offering clear advantages and potential for TDLAS gas detection.
