    • 2004nm 3mW DFB Laser Diode for CO2 Sensing

    2004nm DFB laser diode module is a cost-effective, high-coherence laser source. The DFB laser diode chip is packaged in the industry-standard 14-pin butterfly package with hermetic sealing. A Thermoelectric Cooler (TEC) and a built-in Photodiode (PD) are integrated inside the module. It features excellent Side Mode Suppression Ratio (SMSR) and high optical output power.

    Product features：Narrow linewidth: < 2 MHz；Excellent wavelength control and stability；Industry-standard 14-pin butterfly package；Mode-hop-free tuning；Ultra-high reliability；Customizable wavelength available on request

    Part Number：MP-DFB-2004-3-A81-14BF-SA

    Application area：Tunable Diode Laser Absorption Spectroscopy (TDLAS) | Carbon Dioxide (CO₂) Monitoring
