Abstract

The invention relates to a multi-wavelength integrated infrared semiconductor laser light source, which structurally comprises a coding control module 1, an integrated driving power supply 2, an integrated laser emission unit 3, a rotational positioning transmitting objective lens group 4 and a stepped motor driving system 5. The laser light source has the four emission wavelengths of 0.865 mu m,0.9 mu m, 1.06 mu m and 1.55 mu m and frequency characteristics, and is mainly characterized in that: the high integration of a plurality of infrared wavelength laser light source transmission units is realized by adopting a novel laser diode (LD) / light-emitting diode (LED) machining process, so the configuration of different wavelength infrared semiconductor laser light sources is reduced, a laser transmitter has a smaller volume, a lighter weight and lower cost and is more convenient to operate, and the user requirements of practical work such as comprehensive photoelectric detection, photoelectric equipment acceptance and the like are met. The laser light source has high integration and automation degrees, high transmission efficiency, convenience of online detection, high universalityand high cost performance.
