A tunable diode laser-based sensor for remote sensing of methane (CH_{4) leakage at a wavelength of 1,65 um was developed. The 1.65 um distibuted feedback (DFB) diode laser has a narrow line width and wide tuning range. It was found that the sensor nac detect a 10 cm3 min -1 city-gas leak with a sensor output equivalent to the range-integrated concentration over 100 ppm m.}
