This product is a distributed feedback (DFB) semiconductor laser specifically designed for methane (CH4) gas detection. Its center wavelength is precisely locked at 1653.7 nm, perfectly corresponding to the characteristic absorption peak of methane molecules, making it an ideal light source for building highly sensitive gas sensing systems.

Precise wavelength locking: With a center wavelength of 1653.7nm, it is optimized for CH4 detection to ensure highly selective measurement.

Narrow linewidth output: By adopting a DFB structure, narrow linewidth laser output is achieved, which effectively improves spectral resolution and meets the requirements of high-precision detection technologies such as TDLAS.

Integrated temperature control: The built-in heating temperature control mechanism integrates a low-power heating chip and a high-precision temperature sensor to achieve precise and stable control of the laser's operating temperature, ensuring wavelength reliability during long-term operation.

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