ASE-2000-500-SM-M 2000nm Band 500mW ASE Light Source SM Fiber Laser Module
The 2000nm band ASE broadband light source uses short-wavelength laser pumping thulium-doped fiber and single-mode fiber output. The spectrum covers 1780~2000nm. It has a wider coverage range and greater power than the standard 2μm broadband light source, and is suitable for applications such as laser biology and spectral measurement.
Note: 4~8 weeks lead time.
