Narrow-linewidth DFB laser systems optimized for gas detection, spectroscopy, and optical sensing.
GD Series
Description
The GD series is a line of CW distributed feedback (DFB) lasers with TEM00 mode that are specifically designed for gas detection applications. The laser series features TEM00 mode, narrow linewidth up to 3MHz, no jump mode output in operating current range, compact design, high power and wavelength stability, and FDA-compliant system with driver. The laser is widely used in optical fiber gas detection system, optical sensing, fiber communications, measurement, communication, spectrum analysis, and many other applications.
The GD series DFB lasers are specially designed for gas detection of methane CH4 (1650.9nm, 1653.7nm), Hydrogen sulfide H2S (1578nm, 1590nm), Ammonia NH3 (1512nm), water H2O (1368nm, 1392nm), Carbon monoxide CO (1567nm), Carbon dioxide CO2 (1580nm), Acetylene C2H2 (1532.68nm), Hydrogen fluoride HF (1268.7nm, 1273nm, 1305nm, 1312nm), Ethylene C2H4 (1620nm, 1625nm, 1627nm), etc.
