Quantum cascade lasers are semiconductor lasers that offer peak emission in the mid-IR range (4 μm to 10 μm). These devices are an excellent light source for mid-IR applications, such as molecular gas analysis and absorption spectroscopy. While DFB lasers achieve extremely narrow single-mode bands, our technology can also be customized for more tunable lasers. Hamamatsu’s quantum cascade lasers line lead the industry with meticulously manufactured performance at cost-effective prices.

It is a pulse quantum cascade laser capable of broad wavelength sweeping and has an external cavity configuration.
The lens-integrated package for DFB-CW QCLs provides a collimated beam in a sealed housing.
Single phonon resonance-continuum depopulation (SPC) and distributed feedback (DFB) structures realize stable single-mode emission at room temperature.
