Quantum Cascade Lasers (QCL)
Quantum Cascade Lasers (QCL)
DFB-CW Type QCL
Quantum Cascade Lasers, which emit single mode mid-IR laser beam under the room temperature by employing Single Phonon Resonance-Continuum Depopulation (SPC) and Distributed Feedback (DFB) structures.
By controlling the chip’s operating temperature through the Peltier element installed in the HHL package, it is possible to tune the emission wavelength without mode hopping while keeping longitudinal single mode operation.
DFB-CW Type QCL (Built-in lens)
The lens integrated package for DFB-CW type QCL is sealed and collimated housing. Internal lens provides collimated output beam radiation. TEC (peltier) and thermistor for temperature stabilization of QCL-laser chip are inside the housing.
The lens integrated package allows to use under good usability without beam alignment of invisible mid-infrared laser.
DFB-Pulsed Type QCL
Quantum Cascade Lasers, which emit single mode mid-IR laser beam under the room temperature by employting Single Phonon Resonance-Continuum Depopulation (SPC) and Distributed Feedback (DFB) structures.
By controlling the chip’s operating temperature through the Peltier element installed in the TO-8 package, it is possible to tune the emission wavelength without mode hopping while keeping longitudinal single mode operation.
Pulsed QCL Module
The Pulsed QCL Module is a compact module containing a TO-8 can packaged pulsed DFB quantum cascade laser, pulse driver and TEC temperature controller.
The module can be easily put to use and controlled remotely via Ethernet connection.
