Shijia Photon’s Gas Sensing SeriesSemiconductor Lasers are engineered with cutting-edge Distributed Feedback (DFB) technology, ensuring a pure single longitudinal mode light emission. Integrated with Thermoelectric Cooling (TEC) systems, optical isolators, and backside detectors, these lasers are encapsulated in customizable packages, specifically designed for hermetic sealing. Targeting the near-infrared spectrum, they offer a versatile range of wavelengths tailored to customer specifications.
With operational capabilities spanning from -40°C to 85°C, these lasers maintain exceptional stability in both optical wavelength and power output. Their robust performance makes them ideal for applications in optical fiber sensing systems and Tunable Diode Laser Absorption Spectroscopy (TDLAS) for advanced gas analysis across various industries.
