Room-temperature fiber laser at 3.92 μm
WebFiber lasers based on erbium-doped fluoride fibers (or other doped mid-infrared fibers) can emit at wavelengths e.g. around 2.8–2.9 μm. Similarly, holmium-doped fiber lasers have been developed which emit around 3 μm [4, 9] and at 3.9 μm [3, 25], in addition to the more common region of 2–2.2 μm. WebJan 5, 2009 · All tests were conducted under the laboratory environment at room temperature (at 23°±3°C and 50%±5% relative humidity). Ten specimens were tested at 300, 400, 600, 1000, and 1500 μm span length and 20 specimens were tested at 200 μm span length. Figure 1 Open in figure viewer PowerPoint
