This product is a distributed feedback (DFB) semiconductor laser specifically designed for the detection of carbon monoxide (CO) and carbon dioxide (CO₂) gases. It offers two center wavelength options: 1570nm (corresponding to the CO absorption peak) and 1572nm (corresponding to the CO₂ absorption peak), perfectly matching the characteristic absorption of the target gas. It is an ideal light source for building high-sensitivity, low-cost gas sensing systems.

Precise wavelength locking: The center wavelength can be selected as 1570nm (CO) or 1572nm (CO₂), optimized for the detection of the corresponding gas, ensuring high selectivity measurement and effectively avoiding cross-interference from background gases.

Narrow linewidth output: The DFB structure enables narrow linewidth laser output, effectively improving spectral resolution and fully meeting the needs of high-precision detection technologies such as TDLAS.

Integrated temperature control: Built-in TEC thermoelectric cooler and high-precision thermistor enable precise control and bidirectional adjustment of the laser's operating temperature, ensuring wavelength lock and long-term reliability over a wide temperature range.

High power stability: It provides stable and powerful optical output to ensure signal strength and improve the detection limit.
