Summary: | The utility model discloses a fuel gas detection TO laser assembly, which comprises a tube socket, a chip and a light-emitting ridge, and is characterized in that the chip is arranged on one side of the tube socket and is used for emitting laser; and the light-emitting ridge is arranged on the chip and is electrically connected with the chip. The advantages of simple packaging process without refrigeration and low cost are adopted, on the basis, two light-emitting ridges are manufactured on a chip, lasers with two peak wavelengths are output, the two laser beams are responsible for a low-temperature detection system and a high-temperature detection system respectively through a certain scanning range, the absorption peak of methane can be scanned within the full-temperature range through practice testing, and the detection accuracy is improved. Therefore, the problem that conventional packaging without refrigeration is affected by environment temperature is solved. Through chip structure optimization, the gra |
