Amplification of a Single-Frequency Interband Cascade Laser Around 3240 nm Using a Dysprosium-Doped Fluoride Fiber

Over the last few decades, incredible advances in mid-infrared (Mid-IR) sources and components have enabled the rapid adoption of these technologies in many applications. This region of the electromagnetic spectrum has great potential for growth, as it contains the strong fundamental resonances of most important gases [1]. In particular, new mid-infrared sources are increasingly used in remote sensing applications [2].
