1695-2140nm Fiber DFB laser
Design Tools
1695-2140nm Fiber DFB laser Precilasers' narrow linewidth thulium-doped fiber DFB laser is realized by writing fiber gratings on thulium-doped fiber, which can achieve the full range of 1695-2140nm. It is widely used in quantum computing, for example, 1762nm can be used in quantum computing systems based on Ba+.
