Near and Medium Infrared Fiber Optic Lasers and Applications

The demand for efficient optical active devices operating in the near and medium infrared wavelength ranges is originated from different needs. This wavelength band is of strong interest in a number of applications as remote sensing, sensors, optical communication, medical and military technology. The paper is a review on the NIR and MID-IR fiber NIR, also with reference to the host materials and the dopants employed for their construction, and the corresponding applications. An example of MID-IR fiber optic laser design is mentioned.
