    • 5.26um 20mW DFB-CW QCL Continuous Wave Quantum Cascade Laser

    QCL is a semiconductor laser emitting in the mid‑infrared range (4 μm to 10 μm). Due to its emission mechanism being completely different from conventional laser diodes, QCLs have attracted significant attention as an innovative solution for mid‑infrared applications such as trace gas analysis in environmental monitoring.

    Product features：Continuous wave output; DFB single-mode characteristics; precise temperature control; low-noise driving; industrial-grade package

    Part Number：MP-QCL-5260-DFB-20

    Application area：Gas Sensing | Medical Diagnostics | Defense and Security | Environmental Monitoring | Semiconductor Metrology
