    • 7.2μm Low-Power Benchtop DFB-QCL Mid-Infrared Quantum Cascade Laser (TDLAS Integrated Control Module)

    The QCL7200 – 7.2μm Low-Power Benchtop DFB-QCL Mid-Infrared Quantum Cascade Laser is the first ultra-low-power QCL DFB laser developed by IdealPhotonics in the first half of 2018. With a tunable range exceeding 100nm and an output power greater than 40mW, it meets the industrial demands for gas sensing and testing applications. Our laser provides collimated output with stable power and exceptional temperature-wavelength stability, surpassing traditional high-power quantum cascade lasers by several orders of magnitude. This makes it an optimal testing light source for customers in mid-infrared applications.

    Product features：Low power consumption, high output power、 Narrow linewidth、 Compact structure、 Intelligent software control、 Built-in FPGA

    Part Number：--

    Application area：TDLAS N₂O high-precision trace analysis、 Mid-infrared test light source、 Mid-infrared device analysis

    Notes:

    1.Output power can be customized based on requirements.

    2.Peak operating wavelength can be specified by the user.

    3.Output isolation refers to the isolation level (e.g., against ASE light).

    4. Power stability measured under specified conditions (e.g., 25°C after warm-up).

    5.Power consumption refers to the total electrical power under operating conditions.
