An External Cavity Quantum Cascade Laser (ECqcL™) is a semiconductor laser source patented by Daylight Solutions, which integrates quantum cascade gain media into an external cavity having wavelength dependent feedback. ECqcLs™ are available as either precision fixed-wavelength sources, or as broadly tunable lasers. A tunable ECqcL™ can tune across the entire gain profile of the QC chip, allowing for tunability of 10% to 25% of the center wavelength.
