1512nm High-Power SM DFB Laser (10mW, TO39 Package, NH3 Detection)
With optimized optical characteristics, the 1512nm single-mode DFB laser is an ideal choice for high-demand sensor system applications. The innovative chip design suppresses high-order longitudinal and transverse modes while ensuring linear polarization stability. The laser offers high output power, narrow linewidth, and excellent consistency, making it highly favored by domestic research clients. Currently, we have 1512nm DFB lasers in stock for TDLAS oxygen detection, 795nm VCSELs for Rubidium atomic clock experiments, and 852nm VCSELs for Cesium atomic cooling.
Product features:Ultra-High Output Power、 Narrow Linewidth、 Internal TEC and Thermistor、 2nm TEC Adjustability
Application area:TDLAS Oxygen Analysis and Detection、 Optical Coherence Experiment
