Broadband Fabry-Perot Quantum Cascade Lasers (QCLs) and Interband Cascade Lasers (ICLs)
CW Output: 30 mW for ICLs, Up to 500 mW for QCLs
Center Wavelengths from 3.42 µm to 9.55 μm 
Compact Two-Tab C-Mount Package: 6.4 mm x 4.3 mm x 7.9 mm (L x W x H)
QCLs and IF3800CM2 are Electrically Isolated from C-Mount

The measured output spectrum and L-I-V curve of each serial-numbered device is available below and is also included on a data sheet with the laser. Each Fabry-Perot laser has an HR-coated back facet. As a custom option, our Fabry-Perot lasers can be ordered with an AR coating on the front facet; however, the custom item will operate as a gain chip and not as a CW laser. Though these QCLs and ICLs are specified for CW output, they are compatible with pulsed applications.


These lasers are mounted on a two-tab C-mount that provides high thermal conductivity and can be secured using a 2-56 or M2 screw with the counterbored Ø2.4 mm (Ø0.09") through hole. As measured from the bottom of the C-mount, the emission height of the QCLs is 7.15 mm, while that of the ICLs is 7.0 mm (IF3420CM1 and IFC3550CM1) or 7.28 mm (IF3800CM2); the outer dimensions of the C-mounts are the same. QCLs and IF3800CM2 are electrically isolated from their C-mounts, while the other two ICLs are not.

Drivers and Temperature Controllers

The typical operating voltages of our ICLs and QCLs are 2.5 - 3.1 V and 7 - 16 V, respectively. These lasers do not have built-in monitor photodiodes and must be operated in constant current mode.

The applications:

Used to absorption of carbon monoxide and carbon dioxide

Quantum cascade lasers (QCLs) are semiconductor lasers that emit in the mid- to far-infrared portion of the electromagnetic spectrum
