摘　　要：A 1.65μm three-section distributed Bragg reflector （DBR） laser for CH4 gas sensors is reported. The DBR laser has a wide tunable range covering the R3 and R4 methane absorption line manifolds. The wavelength tunability properties, temperature stability and laser linewidth are characterized and analyzed. Several advantages were demonstrated compared with traditional DFB lasers in harmonic detection.A 1.65μm three-section distributed Bragg reflector （DBR） laser for CH4 gas sensors is reported.
