Room temperature mid-infrared fiber lasing beyond 5 µm in chalcogenide glass small-core step index fiber
(2021)
Journal Article
We report mid-infrared fiber lasing for the first time above 5 µm in a room temperature, Ce 3+ doped, chalcogenide glass, step index fiber using in-band pumping with a 4.15 µm quantum cascade laser. The lasing fiber is 64 mm long, with a calculated n... Read More about Room temperature mid-infrared fiber lasing beyond 5 µm in chalcogenide glass small-core step index fiber.
