2000nm DFB Laser are those DFB Lasers with 2000 nano meter wavelength, including 1970nm - 2050nm Lasers.
These 2000nm DFB laser diode modules are cost effective, highly coherent laser source. The DFB laser diode chip is packaged in an industry standard hermetically sealed 14 pin butterfly package with TEC and PD Built in. And we also customize any other packages .
What does highly coherent laser mean?
Laser radiation is highly coherent, which means the waves of light emitted have a constant relative phase. The waves of light in a laser beam are thought of as in phase with one another at every point. The degree of coherence is proportional to the range of wavelengths in the light beam, or the beam's monochromaticity.
