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.

Distributed feedback (DFB) structured QCLs that emit a continuous wave (CW), single-mode mid-infrared laser beam at room temperature. The emission wavelength can be tuned by controlling the chip’s operating temperature.
The lens-integrated package for DFB-CW QCLs provides a collimated beam in a sealed housing. TEC (peltier) and thermistor for temperature stabilization of the QCL-laser chip are inside the housing.
Distributed feedback (DFB) structured QCLs that emit a pulsed, single-mode mid-infrared laser beam at room temperature. The emission wavelength can be tuned by controlling the chip’s operating temperature.
Compact module containing a TO-8 can packaged pulsed DFB quantum cascade laser, pulse driver, and TEC temperature controller. Easy to use and offers remote control via Ethernet connection.
